After fitting our Polybush Comfort Grade Kit 38 to this particular car, we wanted to see how it behaved when the owner pushed it properly — not just the usual B-road jaunt, but a genuine track session with some spirited driving.
If you want to see the original installation and explanation of Comfort Grade, you’ll find that video here: https://youtu.be/azyvqagMbOU
Driver Feedback: Comfort Bushes Under Pressure
The owner’s verdict was glowing. He already expected the Comfort Grade bushes to improve road manners — that’s their wheelhouse — but what took him by surprise was how composed they remained once the pace went up.
Even in faster corners, the BGT felt predictable and settled. Turn-in improved thanks to more stable geometry, the back end stayed planted, and mid-corner bumps didn’t knock the car offline. In his words: “It feels like the MG I know, just… sorted.”
And that’s exactly what Comfort Grade is meant to do: keep the classic feel, but tidy up the slack that ageing rubber introduces.
Why Polybush Outperforms Rubber — On Road and Track
Rubber is fantastic when fresh, but it breaks down quickly with heat, oil, age and use. Once it softens or cracks, your suspension geometry starts wandering, which is why old classics can feel vague or unstable.
MG BGT – Comfort Grade Bushes
Our polyurethane bushes maintain their shape and resilience for years — often decades — delivering:
consistent handling
sharper steering feel
improved ride quality
vastly better long-term durability
And, importantly, every Polybush product is British-made, engineered and manufactured right here in the UK. These cars were built for British roads, so the parts should be as well.
Different owners want different behaviours from their MG, so we offer three tailored grades:
Comfort Grade (Blue)
The setup used in our track test. Perfect for everyday road use, long tours and maintaining that classic MG suppleness.
Better control, without making the car feel modern or harsh – See Our Blog
Dynamic Grade (Orange)
A brilliant option if you want a bit more sharpness and response. It’s ideal for fast road driving — a livelier, more eager feel, but still perfectly civilised.
Think of it as giving the car a bit more “pep in its step”, without compromising comfort – See Our Blog
Performance Grade (Red)
For drivers who really lean on the car. Perfect for track days, competition, or anyone wanting maximum precision.
It’s the most focused, most durable option for high-stress use.
Track-Day Takeaway: The MG BGT Still Has Plenty Left to Give
The biggest win from the day was how natural the upgrade felt. The owner climbed out of the car smiling, because the BGT didn’t feel drastically changed — it just felt like its best self.
That’s the philosophy behind Polybush: Enhance the classic, don’t overwrite it.
Whether you choose Comfort, Dynamic or Performance, everything we make is:
British-made
Engineered for British cars
Designed to last
Tested on real roads and real circuits
For anyone restoring, upgrading, or simply enjoying their MG BGT, Polybush will help it feel tighter, more controlled and far more confidence-inspiring — without stripping away the charm that makes these cars so loved.
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.

Abarth 500e (332) (2023-On)
Abarth 500e Convertible (332) (2023-On)
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.
Fiat 500 Arm OEM 51857021 Failure – Web
🔧 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.
Polybush Fiat 500 & 500E Suspension Bushes
🔧 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.
Fiat 500 OEM 50709731 – Failure
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.”
Polybush 24U Fitted To A Fiat 500
Polybush 24T & 24U Fitted To A Fiat 500 Front Wishbone
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.

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.
🛒 Order yours today or get in touch to discuss your vehicle – we’re here to keep classics like the Murena driving as they should.
27AL: The Only Way to Solve the MX‑5 MK4 Rear Hub Bush (Knuckle) Problem 🛠️
You’re not alone if you’ve ever heard a clunk from the rear of your MX‑5 MK4 or RF when passing over potholes or uneven surfaces. A well‑known Achilles’ heel of the MK4 is the rear hub‑carrier bushes (which are spherical bearings) – Mazda doesn’t sell them individually. Your only OEM fix?Fitting a complete hub assembly on both sides at over £400 each (plus £160/hour labour), totalling around £1,600 all inmx5life.com+9forum.mx5oc.co.uk+9forum.mx5oc.co.uk+9.
“Mazda don’t sell them as a standalone part…you have to replace the entire hub carrier”
— from MX‑5 Owners Club
Owners frequently report hearing a distinctive knock or rumble from the rear suspension—that’s the failing spherical bearing inside the hub.
Sealed Spherical Bearings These contain a spherical bearing with rubber seals. Over time, those seals degrade, allowing water, grit, and grime in. The result? Premature wear, excessive play, and that dreaded rear clunkforum.mx5oc.co.uk.
Design The spherical design, although space-efficient, fails to resist contaminants in the long term, as evidenced by the hub issues that appear even at low mileages (20–40k miles).
The original Mazda bush fails when water gets inside the bushing.

Frequently Asked
Q: Will it make the ride overly stiff? A: Not at all. 27AL is engineered with the ideal (hardness) durometer. As one forum member noticed: “Ride quality and comfort continue to be excellent too, so there’s no compromise…”bofiracing.com+7mx5parts.co.uk+7mx5parts.co.uk+7.

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
Perfect for Fleets and Daily Workhorses
Taxi fleets can’t afford vehicles sitting in the garage. Whether you’ve got two cabs or twenty, fitting Polybush 55A means:
More uptime
Lower maintenance costs
Consistent ride quality for customers
Happier drivers, fewer complaints
It’s the kind of fix that just makes sense.

We were thrilled to welcome Fraser and the team from LR Centre—one of our local Land Rover distributors—to Polybush recently, giving them an exclusive, behind-the-scenes look at how our legendary polyurethane suspension bushes are made from start to finish. If you’ve ever wondered what goes on in a British workshop that invented both the Polybush product and the Polybush brand, read on!
From Mould to Finished Bush: A Speedy Tour
Mould Making in the Machining Department Fraser got to see our in-house machinists crafting the precision steel moulds that give each bush its shape. Accuracy here is vital: a fraction of a millimetre can make the difference between a perfect fit and premature wear.
Casting: Bringing Polyurethane to Life Next, our casting team pours and cures high-grade polyurethane into those moulds. This is where we introduce our secret formulations to control hardness, rebound and durability.
Trimming and Quality Control Finally, the trimming department cleans up each bush to remove any flash or excess material, ensuring smooth installation. We won’t bore you with every snip and buff, but rest assured every bush passes rigorous checks before it leaves our UK factory.
Polyurethane vs Rubber: Myth-Busting
Whenever you shop for suspension bushes, you’ll encounter two camps: rubber or polyurethane. Here’s why we consistently recommend polyurethane:
Longevity: Unlike rubber, which can perish, crack or swell with age and heat, polyurethane retains its properties for years, even under extreme off-road or performance use.
Precision Feel: Rubber can feel vague or mushy. Polyurethane delivers a more predictable response, so you know exactly how your Land Rover (or any car) will behave.
Customisation: Think polyurethane is always rock-hard? Think again.
Hardness Is Not One-Size-Fits-All
One of the biggest myths is that all poly bushes are “concrete hard.” At Polybush, we offer a spectrum of grades for Classic & Land Rover:
Grade
Shore Hardness
Ideal For
Performance
85 ShA
High-speed or towing.
Dynamic
75 ShA
Every day, driving with a firmer feel
Comfort
65 ShA
Street-friendly, close to rubber softness
“Feel” is all about understanding what you want from your vehicle—whether that’s razor-sharp steering or a supple ride over country lanes. Our job is to match the right bush to your driving style.
Defining Your Land Rover Persona
There are many types of Land Rover owner, so it’s crucial to:
Choose the Right Material Do you crave the compliance of rubber for classic cruising, or the precision of polyurethane for modern performance?
Know Your Usage
Weekend Explorer: Comfort grade for trails and tarmac.
Daily Driver: Dynamic grade for a drive that’s not only comfortable, but direct and controlled at speed.
Remapped / Towing: Performance grade built to withstand heavy use, for those craving speed or towing.
Defining your “Driver Persona” guarantees you pick the ideal bush—and that’s a promise few competitors make.
Why Polybush Stands Out
100 % UK Made: From raw steel to finished product, every step happens under one roof in Britain.
Pioneers of Polybush: We didn’t just adopt polyurethane; we invented the product and the brand nearly 40 years ago.
Unrivalled Quality: Our commitment to quality control and in-house design means you get a bush that outperforms every time.
Whether you’re fitting a Defender, Discovery or Dream-Car, Polybush remains the go-to choice in the Land Rover market.
Beyond Land Rovers
Polybush isn’t exclusive to classic and modern Land Rovers. Our bushes fit a vast array of vehicles:
If it’s got suspension, we’ve almost certainly got a polyurethane bush to improve its ride and handling. Non-Standard or even custom-made?
