Are you sick of the dreaded Transit dogbone mount failing on your Ford Transit V362/V363 (2013–2023)? You’re not alone. At Polybush, we’ve been listening to Transit owners, van converters, tradespeople and fleet mechanics who keep seeing the same issue crop up again and again — the lower torque mount (often called the dogbone mount) simply doesn’t last when left in standard rubber form. That’s exactly why we developed the 40DQ Lower Torque Mount Insert.
40DQ – Ford Transit Mk8 Lower Torque Mount
This isn’t just another “replacement part” — it’s a genuine performance and durability upgrade for a known weak point on these vans.
What This Fits (OEM Part Numbers)
Our 40DQ Lower Torque Mount Insert is engineered to be installed into the original mount housings for the following OEM part numbers:
Let’s break it down in simple terms: the lower torque mount (dogbone) is there to control engine and transmission movement under load — especially on acceleration, deceleration and gear changes. In a Transit carrying heavy payloads or towing regularly, that mount sees a lot of abuse.
The trouble is, the factory uses rubber in these mounts. While rubber is quiet and cheap, it has some critical weaknesses:
Rubber Weaknesses
Age hardening: Rubber hardens over time, especially when exposed to heat and engine bay oils.
Creep & distortion: Under constant torque loads, it stretches and deforms.
Water/oil contamination: Oil and road grime degrade rubber faster than you expect.
Loose feel: As it deteriorates, the engine moves more — leading to clunks, vibrations and stress elsewhere.
Search forums like TransitCenter or social groups on Facebook, and you’ll find countless owners complaining “dogbone mount snapped again”, “engine shifting under acceleration”, or “harsh vibration when pulling loads”. This is exactly the failure mode that cheap-as-chips rubber replacements can’t fix — because they’re the same material Ford originally used.
Maintains torque control without letting the engine flop about
Reduces harsh vibration without making it uncomfortable
Greatly extends life compared with OEM rubber
This isn’t “rock hard” street racer stiffness — it’s engineered to strike the right balance for a working van.

Put simply: polyurethane does the job rubber was supposed to do — but better and for longer. It doesn’t sag or deform under load, it’s far more resistant to oil and heat, and it won’t turn into a brittle lump after a few years on the road.
So while rubber is comfortable when new, it’s a known failure point on high-stress parts like the Transit dogbone mount. Polyurethane keeps its shape, keeps your engine centred and keeps the van feeling tighter over more miles.
What This Means for You
Whether you’re a fleet manager tired of repeat failures, a van lifer prepping your Transit for a round-Europe tour, or a tradesperson relying on your van every day, the 40DQ Lower Torque Mount Insert is an upgrade that makes practical sense:
Less downtime
Reduced vibration/noise
Improved drivetrain control
Longer service life
No need for expensive aftermarket “heavy duty” rubber parts
Final Word
The Transit dogbone mount might be easy to overlook — until it fails. And when it does, you feel every gear change and hard acceleration. Our 40DQ insert isn’t about making your van feel “racey” — it’s about giving you confidence that the mount won’t be the next thing to let you down.
If you’re after a reliable, durable, engineered solution rather than a stop-gap rubber replacement, this is it.
When Aston Martin Works Ltd get in touch, you know the brief won’t be about volume – it’ll be about getting things right.
That was exactly the case when Aston Martin Works contacted us to discuss custom-manufactured suspension bushes for one of the rarest cars ever to leave Newport Pagnell: the Lagonda Rapide.
Supporting One of the Rarest Aston Martins Ever Built
Only 55 Lagonda Rapides were ever made, and it’s believed that just 49 remain on the road today. This isn’t a car you experiment on, and it certainly isn’t one where “near enough” will do. Aston Martin weren’t looking for quantity. They were looking for quality, accuracy, and longevity – which is precisely why they came to Polybush.
Aston Martin Lagonda Rapide – With Polybush Suspension Bushes
As a long-standing British manufacturer of polyurethane suspension bushes, we’ve been synonymous with polyurethane for over four decades. In fact, we believed in it so strongly that we trademarked the Polybush name over 40 years ago. It’s not just what we do – it’s what we’re known for.
Recreating OEM Performance – Properly
The goal from Aston Martin Works was clear: Produce bushes for the Lagonda Rapide that were as close to OEM specification as possible, while benefiting from the inherent advantages of modern polyurethane.
To achieve that, Aston Martin supplied us with original factory bushes and detailed dimensions. Working closely with their Chief Parts Advisor, our design engineer, Greg, meticulously benchmarked each original bush.
This process isn’t guesswork. Every critical dimension, void, bond and compliance characteristic was measured and analysed. The result was the ability to faithfully replicate the original behaviour of the suspension – not just how it fits, but how it feels on the road.
For a car like the Lagonda Rapide, that matters. Owners expect not only performance and stability, but also the comfort and refinement befitting an Aston Martin.
Diagram of Polybush made suspension bushes for the Aston Martin Lagonda Rapide (1961-1964)
Engineering a Low-Volume, High-End Solution
The project involved the development of:
A double-bonded suspension bush
A bespoke radius arm bush
Both were engineered specifically for this application and produced as a low-volume, high-end product, exclusively for Aston Martin Works Ltd. Once fitted, the feedback spoke for itself:
“Thank you for sending the bushes. I’m very pleased to report our technician has fitted them with no issues and the car is back on its wheels and mobile.”
That’s always what you want to hear – especially when dealing with something this rare.
Exclusive Supply, Shared Exposure
Given the uniqueness of the Lagonda Rapide and the bespoke nature of the bushes, we agreed that these parts would be:
Exclusively produced for Aston Martin Works Ltd
Unavailable for direct purchase from Polybush
Instead, Aston Martin Works are listed as the official supplier of these components. It’s a sensible arrangement that protects the integrity of the vehicle, while increasing exposure for both companies – and it ensures customers get the right part, from the right source. You can purchase these parts directly HERE
Custom Polyurethane Bushes for Low-Volume Vehicles
Projects like this perfectly demonstrate what Polybush does best.
Our development team can design and manufacture custom polyurethane bushes for:
Low-volume production vehicles
Classic and heritage models
Specialist and performance applications
Whether the priority is comfort, longevity, precision, or outright performance, polyurethane allows us to engineer those characteristics into the bush from the outset – rather than compromising with a one-size-fits-all solution.
Polyurethane vs Rubber: Why It Matters
Traditional rubber bushes have their place, but they also have limitations:
Rubber degrades with age, oil, heat and ozone
Compliance changes over time
Dimensional accuracy can be inconsistent
By contrast, polyurethane suspension bushes offer:
Far greater resistance to wear and environmental damage
Consistent performance over time
The ability to fine-tune stiffness and compliance for the application
Improved steering precision and suspension control
Crucially for cars like the Lagonda Rapide, polyurethane can be engineered to deliver comfort as well as control – it’s not just about stiffness.
Hand-Cast, Made in the UK – Why That Still Matters
All Polybush products are hand-cast in the UK, allowing us total control over materials, quality, and consistency. For specialist projects, this approach is invaluable.
It means:
Tighter tolerances
Better bonding
Proper quality control at every stage
The flexibility to manufacture genuinely bespoke components
It’s also why manufacturers like Aston Martin Works trust us with rare, irreplaceable vehicles.
A Partnership Built on Quality
Working with Aston Martin Works Ltd on the Lagonda Rapide has been a genuine privilege. It’s a perfect example of how traditional British engineering, modern materials, and careful development can come together to preserve some of the finest cars ever made.

That’s where our new Polybush 1BD Caster Correction Bushes come in. Specifically designed to suit vehicles fitted with Radius Arm NTC2694, these polyurethane bushes are engineered to correct the caster angle for vehicles with 2–3″ lift kits. If your Landy is running standard ride height, we’ve still got you covered – that’s what our Polybush 1B bush is for.
What is Caster, and Why Does It Matter?
Caster is the angle between your steering axis and vertical, viewed from the side of the vehicle. In simple terms, it’s what helps your wheels return to centre after a turn and keeps your steering stable at speed.
Caster Explanation
When you lift a solid axle Land Rover, the fixed geometry of the radius arms shifts, effectively rotating the axle and reducing positive caster. And that reduced caster leads to:
Wandering on the road – poor straight-line tracking
Increased tyre wear – as the tyres scrub across the tarmac
Vague steering – you constantly correct the wheel
Speed wobbles – especially on uneven roads or at motorway speeds
Correcting the caster restores your handling, improves tyre life and puts you back in control – exactly what the 1BD Caster Correction Bush is designed to do.
1BD – Caster Corrected Bushes for 2-3″ Lift
Can They Be Fitted Easily?
Absolutely, they can! On purchase, we provide easy-to-read fitting instructions for all products that have to be fitted in a certain way.
You can also find them here – 1BD Fitting Instructions & on the vehicle page.
Though we always recommend a press, in the majority of cases, you can install our bushes by hand, or with simple hand tools. But due to the 1BD’s outer metal shell, you’ll need to make a tool with a threaded bar and some sockets. We created a video showing this HERE – Or, use a press/vice.
Why Polyurethane? Why Polybush?
Traditional rubber bushes can’t always cope with the demands of a lifted Land Rover – they flex more, degrade faster under load, and can allow the geometry to shift subtly under braking or cornering.
Polybush bushes, on the other hand, are:
Durable – they resist oil, fuel, weather and UV, lasting far longer than rubber
Consistent – they hold their shape under load, giving more predictable handling
Responsive – more positive road feel without harshness
No squeaks, no maintenance – thanks to our unique Polyurethane blend and precise fitment
In short, they’re built to handle everything from green lanes to gravel tracks to long hauls on the M6, towing plant machinery – and they do it with comfort and control.
How Will It Feel on the Vehicle?
Fit a set of 1BD bushes and you’ll notice the difference straight away:
Steering feels more direct and centred – the vehicle stops “drifting” around its lane
High-speed stability improves – less correction needed at motorway speeds
Better off-road control – especially when descending or crawling, as the geometry keeps the steering more predictable
Improved tyre wear and alignment – no more fighting uneven wear caused by incorrect angles
It’s the kind of improvement you feel as much as you see – and when you’re miles from home, that reassurance matters.
Built for the Road. Proven Off It.
At Polybush, we design every bush with real-world use in mind. Our 1BD bushes aren’t just good on paper – they’re proven in everything from fully-kitted overland rigs to daily-driven Defenders that hit farm tracks Sunday and the motorway Monday.
So if you’ve given your Land Rover a bit more altitude, don’t forget to sort the attitude – get your caster back to where it should be with Polybush 1BD Caster Correction Bushes.
If you’ve got questions about fitting, compatibility, or how these work with your suspension setup, give us a shout – we’re always happy to help fellow Landy fans get their trucks handling right.
Solving the Mitsubishi Outlander PHEV’s Most Common Mounting Problem – Polybush 17AW
The Outlander PHEV’s Balance of Efficiency and Engineering
Since its launch in 2012, the Mitsubishi Outlander Mk3 PHEV (GF, GG, ZJ, ZK, ZL) has been a game-changer in the plug-in hybrid market. It offers electric efficiency combined with petrol reliability, making it one of the most popular hybrid SUVs in the UK and Europe.
However, beneath the smooth, silent running of its electric powertrain lies a known weak spot – the rear motor mount, front bracket bush. Owners and technicians alike have found that this particular bush wears prematurely, creating unwanted noise, vibration, and harshness (NVH) that detracts from the refined feel of the vehicle.
17AW Fitted To The OEM Mitsubishi Outlander Motor Mount Housing.
The Problem: OEM Rear Motor Mount Front Bracket Bush Failure
At the heart of this issue is the Rear Motor Mount Front Bracket Bush, found in the rear motor mount assembly (OEM part numbers 3517A090 and 3517A053). This bush plays a vital role: it supports the rear electric drive motor and isolates vibrations from the chassis, ensuring smooth power delivery between electric and petrol modes.
Symptoms of Bush Wear or Failure:
Noticeable vibration through the cabin, especially under acceleration
A “clunk” or jolt when transitioning between drive and regeneration modes
Increased drivetrain movement and harshness when engaging drive or reverse
Reduced comfort and refinement
Hybrid systems generate high torque at low RPM, which puts significant stress on these bushes. Over time, the original rubber compound softens, splits, or even separates from its metal sleeve. Unfortunately, replacement of the full OEM mount is costly – and using the same rubber component means the issue will likely reoccur.
Instead of replacing the entire OEM mount, the Polybush 17AW allows technicians and owners to replace only the worn bush within the existing bracket. This makes it a cost-effective, long-term upgrade that maintains the vehicle’s comfort while greatly improving durability.
Key Features of the Polybush 17AW:
Direct-fit design – Installs into the original mount housing (OEM 3517A090 / 3517A053)
OEM comfort, Polybush longevity – Retains ride quality while improving bush life
Resistant to wear and deformation – Polyurethane resists oil, heat, and road contaminants
Reduces drivetrain movement – Improves response and stability during acceleration
Manufactured and tested in the UK – Ensuring consistent quality and precision
Polybush 17AW, Replacing OE Reference: 3517A053, Part of 3517A090,
Retaining Comfort Without Compromise
One of the biggest advantages of Polybush’s approach is that it doesn’t trade comfort for performance. The 17AWbush has been carefully tuned to maintain the Outlander’s factory refinement, ensuring that vibrations remain isolated while providing firmer support for the hybrid drivetrain.
This means drivers enjoy:
Improved throttle response
Reduced cabin vibration
Greater drivetrain longevity
A more consistent hybrid driving experience
Why the OEM Bush Fails – and How Polybush Fixes It
Rubber bushes like the OEM 3517A090 / 3517A053 are prone to fatigue from repeated load cycles, especially in hybrid vehicles where torque delivery is instantaneous. The soft compound eventually degrades, allowing excess engine and motor movement that stresses surrounding components.
Polybush polyurethane, however, is chemically resistant and mechanically stable. It doesn’t compress or perish like rubber, and its precision moulding ensures proper alignment and load distribution. As a result, Polybush 17AW eliminates the play that leads to premature wear and failure – without increasing NVH.
Simple Installation, Big Improvement
Replacing the bush is straightforward for workshops and experienced DIY enthusiasts. The existing mount is removed, the worn OEM bush pressed out, and the Polybush 17AW pressed in using standard tools. The result is a refreshed, strengthened mount that restores the feel and performance of the Outlander PHEV.

Polaris Rangers are built for work — trusted by farmers, groundskeepers, estate managers and off-road enthusiasts alike.
But even the toughest UTVs (Utility Task Vehicles) have a weak link: their suspension bushes.
From brand-new Ranger 1000 Crew models to well-used Ranger 800s, owners across the UK & US (and beyond) have reported premature bush wear.
The issue is simple — the factory-fitted hard, non-flexible Nylon-like bushes can’t withstand the constant punishment of off-road use, mud, chemicals, and load stress.
That’s where Polybush comes in. Manufactured in the UK and proven in the field, Polybush’s polyurethane suspension bushes transform the way your Polaris handles, lasts, and performs — turning early failures into long-term reliability.
Why OEM Polaris Bushes Fail
Rubber is soft, cheap, and comfortable — but on working vehicles, it’s also vulnerable. Constant flexing and exposure to contaminants like oil, fuel, and cleaning chemicals cause rubber to perish, crack and split. That’s why your Polaris doesn’t have rubber bushes; it has hard plastic bushes. But when you add in heavy loads, side stresses, and daily use, it’s no surprise many Polaris Rangers develop knocking noises, vague steering, or uneven tyre wear within months.
Tyre Wear Caused By Failing Bushes
Common failure symptoms include:
Excessive movement in wishbones (Control Arms & A-Arms)
Uneven tyre wear or steering pull
Suspension clunks or squeaks
Poor stability under load
Once this happens, alignment suffers, tyres wear faster, and your Ranger loses that planted, confident feel it had when new.
The Polybush Solution
Polybush’s precision-engineered polyurethane bushes directly replace Polaris OEM rubber components, eliminating the weaknesses of rubber while preserving comfort and flexibility.
Unlike rubber and Nylon, polyurethane resists oil, fuel, UV, and high-pressure washing — meaning your suspension geometry remains correct and consistent for the life of the vehicle.

Polybush bushes are available for every major Polaris Ranger model from 2010 onwards. Below is a breakdown of common factory issues and how Polybush solves them.
OEM rubber bushes in the control arms (A-Arms) often deform quickly, leading to vague steering and noise. Polybush 53A and 53E replace these with durable polyurethane, maintaining correct alignment even under heavy loads.
The most common complaint is excessive play in the lower wishbone (A-Arm) bushes and rear hub mounts. Our kits 228 and 229 replace OEM 5452233 and 5139966 bushes, restoring precision and stability.
The 800’s heavy-duty chassis puts real strain on the anti-roll bar and rear upright bushes. Our 53F and 53H bushes prevent deflection and extend lifespan dramatically.
Diesel torque and extra vibration destroy OEM rubber bushes in short order. Polybush polyurethane eliminates premature wear and isolates vibration without sacrificing comfort.
A powerful workhorse with a known weak point — the lower control arm (A-Arm) and rear hub bushes. Polybush kits 234 and 237 provide long-term stability, with polyurethane that won’t compress or crack.
Owners often report poor alignment and a harsh knocking under load. Our complete replacement kits include 53A–53M to ensure every control arm (A-Arm) and shock pivot is properly supported.
The electric XP Kinetic’s instant torque and quiet running make bushing quality vital. Our polyurethane bushes maintain geometry without introducing noise or vibration, ensuring smooth, silent performance.
For electric and estate-use Rangers, silent operation is essential. Polybush 53L and 53M provide durable, noise-free shock absorber mounts that last for years without deterioration.

That’s a huge range of cars that all suffer from the same weak point – rubber bushes.
Why Rubber Bushes Fail
If you’ve owned one of these cars for a while, you’ll know the story. Rubber bushes crack, split and deteriorate long before the rest of the suspension wears out. Heat, road salt, oils and just plain age all conspire to break them down. Once they go soft or start splitting, the handling falls apart – vague steering, uneven tyre wear, clunks and knocks, and in many cases, an expensive bill just to put it right.
“Every time the wishbone bushes go, it’s a nightmare – bumper off, arms out, and you know you’ll be back under there in 18 months doing it all again.”
That’s exactly why we’ve developed polyurethane replacements. Polybush bushes don’t degrade like rubber, meaning once you fit them, that job is done. No more repeat failures, no more premature MOT advisories, and your car drives like it should.
The New Polybush Range
We’ve launched four key bushes that tackle the main weak points in these cars:
The front bush in rubber – Walks out, causing caster changes, causing vague steering especially at speed. Our polyurethane version resists flex and oil contamination, keeping your geometry stable and your steering sharp.

🔧 24U – Front Wishbone Rear Bush
OE References include: 50709579, 50710620, 51860383, FS51-3078-BA (and many more).
This is the one that causes the biggest headaches. The OEM rubber rear bush is notorious for failing, and replacing it as with the front bush is a proper chore – the front bumper has to come off just to access the bolts. That’s why it makes sense to fit Polybush once, and never have to go through the same pain again.
These bushes support the entire rear axle, so when the rubber fails, you’ll hear knocks and feel instability at speed. Swap to Polybush and the rear end tightens up beautifully – stable, predictable, and long-lasting.
🔧 24V – Rear Shock Absorber Upper Bush (M12)
OE References include: 50709731, 51857841, 9S51-18125-AA (and many more).
Electric versions of the Fiat 500 carry extra weight from the battery pack, putting added strain on the suspension components. The standard rubber bushes often struggle under this increased load, wearing out far sooner than expected.
Our 24V polyurethane bush is engineered to handle the extra mass and torque of the EV drivetrain. It maintains its shape and performance under pressure, giving your shocks the firm, consistent support they need for a smoother, more controlled ride.

🔧 24Y – Rear Shock Absorber Upper Bush (M10)
OE References include: Part of 51857841, 51864833 (and many more).
If you own one of these cars, you’ve probably replaced these more than once already. The OEM rubber fails for fun – it just can’t cope with the repeated loading. That’s where polyurethane really shines. Our 24Y bush shrugs off the punishment, giving your shocks the proper support they need for a consistent ride and handling.

Why Polybush is the Best Choice
Fit once, forget it – no need to replace every MOT cycle.
Resistant to oil, fuel, salt and heat – unlike rubber, Polybush won’t break down.
Improved handling and ride quality – sharper steering, better stability, and a more solid feel.
Cost-effective – especially when you factor in the labour involved in removing bumpers or subframes just to change failed OEM parts.
“Swapping rubber for Polybush is the smartest move – you do it once, and it transforms the way the car feels.”

These cars are fantastic fun, whether it’s a cheeky Fiat 500 nipping through traffic, a tough little Panda taking on back roads, or an Abarth 595 delivering a grin every time you prod the throttle. But they all share the same Achilles’ heel – rubber bushes that simply don’t last.
With Polybush polyurethane suspension bushes, you’ll only need to do the job once. The car will handle better, last longer, and finally live up to the way it should have left the factory.

Polybush Now Manufacturing Polaris Ranger Bushes – The Ultimate Upgrade
Polybush is now manufacturing a full range of polyurethane suspension bushes for Polaris Ranger models, including the Ranger 1000, XP 1000, 902D and the XP Kinetic. If you own one, or even a fleet of these machines, you’ll already know how capable they are – but also how frustrating it can be when the OE bushings give up long before they should.
The standard Polaris bushings are made from a hard plastic. On paper, that sounds tough, but in practice it’s anything but. Hard plastic doesn’t flex, it wears quickly, it knocks, and once it’s gone, your suspension geometry, ride quality and even handling suffer. For a workhorse like the Ranger, that’s unacceptable.
That’s where Polybush steps in.

Why Polyurethane is the Perfect Material
We’ve been making polyurethane bushes in the UK for decades – everything from commercial vehicles and classic cars to high-performance 4x4s. Polyurethane is quite simply the best material for the job:
Durability – It shrugs off abuse, whether it’s heavy towing, off-road punishment or day-in-day-out farm work.
Flexibility – Unlike plastic, polyurethane can absorb and release energy, resulting in reduced wear and a longer service life.
Precision Fit – Our bushes are engineered to exact tolerances, ensuring a snug, knock-free fit.
Performance – Better ride quality, sharper handling and improved suspension life.
And crucially, every single Polybush is manufactured right here in the UK to world-class standards.

Frequently Asked Questions – Polybush for Polaris Ranger
Are Polybushes difficult to fit on a Polaris Ranger?
Not at all. Polybushes are designed as a direct replacement for the OEM bushes. If you’re handy with spanners and already comfortable with removing wishbones or suspension arms, you’ll find the process straightforward. Most customers fit them at home with basic tools, or you can get your local workshop to do it.
Do Polybush bushes need greasing?
No. One of the big advantages of Polybush is that it needs no grease! Unlike some aftermarket bushes that squeak or need regular greasing, Polybushes are made from a specially formulated polyurethane that doesn’t require extra lubrication. Fit them once and forget about them.
How long do Polybushes last compared to OEM plastic bushes?
Polybushes last many times longer than the original Polaris plastic bushes. OEM bushings can wear out frustratingly quickly, especially if your Ranger works hard or lives in mud, dust, and water. Polybushes are designed to cope with exactly those conditions, meaning you’ll be changing them far less often.
Will Polybush make my Polaris Ranger ride harder?
No – quite the opposite. Because Polybushes flex where needed, they actually absorb harshness better than the rigid OEM plastic bushes. You’ll notice a more controlled, quieter and smoother ride, without the knocks and play that develop when plastic bushes wear out.
Are these bushes made in the UK?
Yes – every single Polybush is manufactured in our UK factory. We design, tool, and mould them in-house to guarantee consistent quality. No outsourcing, no cutting corners – just proven British engineering.
Do you sell complete kits as well as individual bushes?
Yes. You can buy individual bushes for specific repairs, or full kits if you’d like to refresh the entire suspension. Many owners opt for a complete kit, ensuring everything is upgraded at once, which ensures perfect alignment and a longer service life.
The Polaris Ranger is one of the most capable side-by-sides on the market – but it’s let down by weak OEM bushings. With Polybush, you get a fit-and-forget Polaris Ranger suspension upgrade that transforms durability, ride quality, and handling.
Whether you run a working Ranger 902D, a family-hauling 1000 CREW, a performance XP 1000, or the all-electric XP Kinetic, Polybush polyurethane bushes give you the confidence your suspension will stay strong, quiet, and reliable for years.
New Release: Polybush 49C Engine Stabiliser Bush for the 2.2L Matra Murena
At Polybush, we’re proud to support classic and rare vehicles with expertly engineered polyurethane components — and our latest release is one that’ll be of particular interest to Matra enthusiasts.
We’re pleased to announce the launch of our 49C Polyurethane Engine Stabiliser Bush, now available specifically for the 2.2L Matra Murena. Originally developed as a shock bush for the Isuzu D-Max Mk2, the 49C has proven to be an ideal fit for this unique French sports car after careful testing and feedback from respected specialists, including Roy Gillard of the Matra Club (www.matraclub.org.uk), one of the world’s leading experts on the marque.
Why a New Engine Stabiliser Bush for the Matra Murena?
The 2.2L version of the Matra Murena is a rare beast — a mid-engined, rear-wheel-drive, lightweight sports car that offers bags of character and a surprisingly capable chassis. However, like many classics, ageing rubber components in the drivetrain mountings can significantly dull its performance.
The original rubber stabiliser bush on these cars is prone to degradation over time, leading to excessive engine movement under load. This movement not only affects refinement but also reduces throttle response and can contribute to wear on the drivetrain. That’s where the Polybush 49C comes in.
Polyurethane vs Rubber: What’s the Benefit?
Unlike natural rubber, polyurethane doesn’t perish, crack or degrade with age or exposure to oil, salt, and heat. That’s a huge advantage for a classic like the Murena, which may not be driven daily — but deserves to feel sharp and responsive every time the key’s turned.
Here’s what you can expect from the Polyurethane 49C Bush:
🔧 Sharper Throttle Response
By better controlling engine movement under load, the 49C reduces drivetrain slop. That means more immediate throttle response, smoother gear changes, and a more connected driving feel. It’s especially noticeable when accelerating hard or shifting quickly — two things the Murena 2.2L loves to do.
🔇 OEM-Level NVH
We’ve carefully tuned the durometer (hardness) of the 49C bush to retain OEM-like NVH characteristics.
What is NVH? NVH stands for Noise, Vibration and Harshness — the trio of comfort-related sensations you feel (or don’t feel) from the engine and chassis. Too hard a bush, and you’ll get unwanted vibration in the cabin. Too soft, and performance suffers.
With Polybush, you get the best of both worlds — performance gains without compromising comfort.
🛠 Durability and Fit
Our bushes are designed to be a direct replacement, with no modification needed. The 49C offers a perfect fit for the stabiliser mounting on the 2.2L Murena and will last significantly longer than rubber, saving time and money in the long run.
Expert Input from the Matra Club
In developing this application, we worked closely with Roy Gillard of the Matra Club, whose knowledge of Matra vehicles is second to none. Roy confirmed the need for a quality replacement in this area of the drivetrain and provided detailed insights into the specific fitment for the 2.2L variant.
“There’s been a need for a modern, durable replacement for the stabiliser bush on the 2.2 Murena for some time. The Polybush 49C is a welcome solution that not only fits correctly but enhances the driving experience without adding noise or harshness.” – Roy Gillard, Matra Club
Only for the 2.2L Murena
It’s worth noting that this bush is only suitable for the 2.2L version of the Matra Murena. If you’re unsure of your model or fitment, feel free to get in touch with us — we’re always happy to help.
Available Now from Polybush
If you want to tighten up the feel of your 2.2L Matra Murena, reduce engine movement, and gain a little more precision from your classic, the Polybush 49C Engine Stabiliser Bush is available now.
Like all Polybush products, it’s manufactured in the UK, built to last, and backed by our expert team of enthusiasts and engineers.

At Polybush, we’re excited to announce our latest product release — high-performance polyurethane suspension bushes for the Land Rover Defender L663, covering the 90, 110 and 130 models from 2020 onwards.
Whether taking on tough terrain or simply navigating the school run, your Defender deserves a suspension setup built to last. That’s where Polybush steps in.

Our polyurethane alternative is designed to retain comfort while delivering enhanced performance and longevity. The result? Sharper handling, reduced bush deflection and dependable suspension geometry — whether you’re on the road or exploring off the beaten path.
Key Benefits of Our Defender L663 Bushes:

If you’re running a TX5(TXE) taxi, either as a sole operator or managing a fleet, chances are you’ve encountered this problem — The rear bush on the front wishbone fails, repeatedly.
It’s the kind of fault that takes vehicles off the road and costs you money in lost time and costly OEM parts. The culprit? The Front Wishbone Rear Rubber Bush (OEM part number 1C0001063AA) housed within suspension arm assemblies 1C0001011AE / 1C0001012AF.
This is the most common point of suspension failure on the TX5 (TXE), and unfortunately, it’s not going away.
The Problem With the Original Bush
LEVC are great during the first five years — they’ll replace worn rubber bushes under warranty. But after that? You’re on your own. And replacing those bushes means shelling out for a new arms, which don’t come cheap.
Rubber, for all its initial comfort, simply can’t cope with the day-in, day-out punishment that a working taxi endures:
Constant start-stop driving
Heavy loads
Speed bumps, potholes, and uneven roads
Exposure to oil, diesel, road salt, and city grime
This combination leads to early deterioration, splitting, and deformation of the rubber bush — often long before the rest of the arm is worn out.
The LEVC TX5 Wishbone Bush Solution: Polybush 55A
Enter the Polybush 55A, specifically engineered as a direct replacement for the TX5’s front wishbone rear bush. Designed and manufactured here in the UK, it’s built from high-performance polyurethane, a material that wipes the floor with rubber when it comes to longevity and durability.
No more LEVC TX5 Front Wishbone Bush Failures With Polybush 55A – Replacing 1C0001063AA, Part of 1C0001011AE, 1C0001012AF
Why polyurethane is the ideal choice for your TX5 (TXE):
4–5 Times the Lifespan of Rubber
Polybush bushes outlast OE rubber bushings by four to five times, meaning less downtime, fewer replacements, and no more prematurely worn-out bushes taking your taxi off the road.
Resistant to Oils, Fuels, and Contaminants
Taxi chassis see everything from spilt diesel to de-icer and road salt — all of which degrade rubber. Polyurethane shrugs them off, continuing to perform mile after mile.
Keeps Comfort, Improves Control
The 55A has been specifically tuned to offer excellent vibration isolation, preserving the ride comfort your passengers expect, while also improving the precision and control that drivers love. You’re not trading comfort for durability — you’re getting both.
Fast, Simple Fit
The 55A fits directly into the original housing. You can press it in without replacing the full wishbone arm, saving time and serious cash. Need some fitting instructions – CLICK HERE

More uptime
Lower maintenance costs
Consistent ride quality for customers
Happier drivers, fewer complaints
It’s the kind of fix that just makes sense.

By fitting Polybush 55A, you’re investing in a fix that prevents failure, not just delays it.
