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.

🔧 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.”

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.

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.
Enter 27AL from Polybush
Polybush 27AL is a bespoke polyurethane replacement kit that resolves the issue at its root.
These aren’t one‑off cases—thousands of MK4 owners (and even Mazda dealers) now depend on 27AL to resolve rear‑end noise, grip issues, and misalignment without breaking the bank.

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.
55A Polybush for LEVC TX5 – Replacing OE Reference: 1C0001063AA
Don’t Let A Bush Cost You £1000s
When a failed bush means your TX5 (TXE) is off the road, you’re not just looking at the cost of parts and labour — you’re losing income. One vehicle out of service can cost a fleet hundreds per day.
By fitting Polybush 55A, you’re investing in a fix that prevents failure, not just delays it.

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?
Head to our “Can’t Find What You’re Looking For” page.
At Polybush, we understand that reliable vehicle performance is essential, especially when your fleet’s efficiency is on the line. That’s why we’re proud to introduce the 39X Rear Axle Bush, the ultimate Polyurethane rear axle bush replacement that outperforms standard rubber bushes by up to 4-5 times in durability.
Why the 39X Rear Axle Bush is a Game-Changer for Rear Axle Bush Replacement
Many fleet operators and van owners have faced the frustrating reality of frequent rear axle bush failures. We were first approached by a local council facing constant issues with standard rubber bushes in their vans. Later, we partnered with Royal Mail to solve their recurring axle bush problems.
The Problem with Rubber Suspension Bushes
Degradation Over Time: Rubber tends to crack and wear out quickly under heavy loads and extreme temperatures.
Chemical and Oil Absorption: Exposure to oils, fuels, and road contaminants accelerates rubber degradation.
Bonding Failures: The bonding agents in traditional rubber bushes can weaken, causing the centre sleeve to de-bond from the outer casing, resulting in unwanted axle movement and unstable handling.
Why Polyurethane is Superior
Our Polyurethane 39X Rear Axle Bush offers a robust solution to these issues:
Exceptional Longevity: Polyurethane resists heat, UV, chemicals, and weather-related degradation, ensuring your vehicle’s rear axle bush lasts significantly longer.
Stable and Secure: Engineered to prevent de-bonding, our bush keeps the centre sleeve firmly in place, eliminating free movement that can lead to rear steering issues.
Consistent Performance: Unlike rubber, which can soften or harden with age, our Polyurethane bushes maintain their performance over time, ensuring reliable vehicle handling and road safety.

You’re in the right place if you’re considering Polybush upgrades for your Land RoverDiscovery 3 or 4. In this blog we’ll delve into what we can do for your vehicle, how it compares with traditional rubber bushes, and why our Dynamic range has been specifically used to maintain that original ride comfort you love.
What Are Polybushes and Why Upgrade?
Polybushes are advanced suspension components made from polyurethane. They replace the conventional rubber bushes found in most vehicles. Unlike rubber, polyurethane offers enhanced durability, resistance to oil and weathering, and a more consistent performance over time. For your Discovery 3 or 4, this means improved handling and longevity without compromising on ride quality.
The Full Suspension Bush Kit For Discovery 3 & 4
Keeping the Original Comfort
A common concern when upgrading from rubber to polyurethane is the fear of a harsher ride. However, our dynamic range of Polybushes are engineered to maintain the original comfort that you expect from your Land Rover. The design ensures that while your vehicle benefits from the increased rigidity and durability of polyurethane, it still absorbs the bumps and vibrations like the original rubber bushes. This means you can enjoy the robust performance required for both off-road adventures and long-distance journeys, without sacrificing the smooth ride that’s crucial for daily driving.
Polyurethane vs Rubber
When it comes to comparing polyurethane with rubber, several key things stand out:
Durability: Polyurethane bushes are significantly more resistant to wear and tear. This translates into a longer lifespan even under challenging conditions, such as towing heavy loads.
Performance: With polyurethane, you gain improved handling characteristics. The bushes provide a more stable and predictable suspension geometry, which is especially beneficial for vehicles like the Discovery that often face varying driving conditions.
Maintenance: Rubber bushes can crack and degrade over time, especially when exposed to harsh conditions. Polyurethane bushes are less susceptible to these issues, offering a more cost-effective solution over the long term.
What It Does for Your Vehicle
Discovery 4 which has covered 70,000 miles with Polybush Fitted
Upgrading to Polybush will noticeably improve your Discovery’s handling and suspension performance. The tighter suspension geometry reduces unwanted movement, leading to better steering response and overall vehicle stability. This is particularly advantageous for drivers who frequently tow or load their vehicles under heavy conditions. Despite these improvements, the comfort level remains intact, thanks to our meticulously engineered designs, ensuring that your drive remains as smooth and enjoyable as ever.
A Happy Owner’s Experience
It’s always great to hear real-world feedback from fellow Discovery enthusiasts. One satisfied owner shared:
“I have had my Discovery series 4 for 15 years. After 30,000 miles or so I had a very nasty crash on the continent. When it finally got back to the UK, the repairer pointed out that the bushes were quite badly worn. We attributed this to the fact that the car spends at least 40% of the time towing a trailer loaded with the competition car. At the repairer’s suggestion, they took the opportunity of replacing all the bushes with Polybush. This year, the car completed one hundred thousand miles so I decided it was time for a thorough check-over. Naturally, there were a few things that needed doing but the garage doing the work told me the Polybush’s were still absolutely fine even after 70,000 miles more of hard work! I thought you might be glad to hear this”
This testimonial highlights not only the longevity of the Polybush product but also their real-world performance in challenging conditions.
Final Thoughts
Upgrading to Polybush on your Discovery 3 or 4 is an excellent choice if you want enhanced durability and improved handling, without compromising the ride comfort you value. Our dynamic range ensures that your vehicle’s suspension remains true to its original design, keeping your journeys smooth whether you’re navigating city streets or tackling rugged terrain.

Hi there, fellow MX-5 enthusiast, Ellis here – Proud owner of a Turbo Mk1 and lifelong MX-5 fanatic.
If you’re anything like me, you love the raw driving feel of the Mazda MX-5 (Especially the earlier models) The perfect balance of nimbleness, top-down thrills, and grin-inducing cornering keeps us coming back for more.
But let’s be honest—after a few years (or decades in my Mk1’s case), certain parts start to let the side down; The humble door bushing can be improved significantly, with extremely low effort & cost.
Ellis’ Turbo Mk1 – Circa 249HP
Let me explain why swapping out the rubber bushings for Polybush’s 27AS polyurethane door bushings is one of the easiest—and most satisfying—upgrades you can make to your MX-5.
What Do Door The Bushings Actually Do?
You know that satisfying thunk when you close a solid car door? That’s partly thanks to door bushings. Those little guys make sure your doors align properly, helping to keep everything rigid and rattle-free. On an MX-5—where chassis stiffness plays a big role in handling—well-aligned doors aren’t just about avoiding squeaks; they’re about keeping that legendary road feel intact.
27AS Installed On Ellis’ Mk1 Mx5
Why Your OEM Rubber Bushings Let You Down
The factory rubber bushings? They’re fine—when new. But Mazda designed them for comfort and cost-effectiveness, not long-term performance. So what that means is: Ageing Woes: Rubber doesn’t age gracefully. Sun, rain, heat—you name it—rubber gets hard, cracks, and eventually just gives up. (This is the same for tyres, suspension bushes etc.) Door Misalignment: As the rubber ages and deforms, your doors start shifting more than they should. There’ll be annoying little rattles, vibrations, and that frustrating “loose door” feel. Potential Knock-On Damage: Misalignment can wear out door latches and hinges. Ignore it for too long, and you could be facing repairs that’ll hit your wallet harder than you’d like.
Why Polybush 27AS Polyurethane Bushings Are The Way Forward
Here’s where Polybush comes in—and let me tell you, after fitting these (and other parts) to my Mk1, the difference was night and day! I think you’ll love them because: Durability That Lasts: Polyurethane laughs in the face of heat, moisture, and UV. These bushings will outlive your car’s engine and we all know they go FOREVER! Rock-Solid Rigidity: Polybush bushings aren’t just stiffer, they’re made to fit the door cup properly, which means less door movement and a more solid feel when you shut the door.
Bonus: it helps preserve that all-important chassis stiffness, and increases audio quality. Bye-Bye, Rattles: With proper door alignment restored, say farewell to those cabin noises that make you crank up the radio. Fit-and-Forget: These are designed to last the lifetime of your MX-5, saving you money, increasing performance and making it a nicer car to drive.
27AS and the Original Mk1 Mx5 Door Bushes – Via MX5Parts
Why Go for Polybush’s 27AS?
The 27AS bushings are fit for all MX-5 generations—Mk1 through Mk4. No faffing about with modifications; they’re a direct swap for the OEM parts. Installation’s straightforward too—if you can handle a screwdriver and an Allen key, you’ll be done in less than 5 minutes. And once they’re in? A satisfying clunk appears, your doors feel secure, the whole car feels just that bit tighter and the audio quality improves.
Where Can You Buy A Set?
Easy—head over to MX5 Parts. They’re our trusted MX5 distributor, they stock everything an MX-5 nut like me (and probably you) could ever need.
Final Thoughts from Ellis
Look, I get it—door bushings aren’t the flashiest upgrade. They’re not shiny wheels or a new exhaust, or in my case, a hybrid turbo! But trust me, the difference in how your car feels is massive for such a small mod. With the Polybush 27AS bushings, my Mk1 feels more solid than it has in years. No rattles, no vibrations—just me, the road, and that pure MX-5 joy.
So why let something as simple as worn bushings detract from your driving experience? Make the swap, and fall in love with your MX-5 all over again.
See you on the twisties!

Tired of endless suspension issues or your Juke, Leaf or X-trail? We’ve got the solution! We’re excited to announce the release of a new range of Polyurethane suspension bushes for several popular vehicles, addressing a long-standing issue that has plagued owners and garages alike.
If you own one of the following, you’re in luck, click to see more:
12AN – Replacing The Main Failure Bush on Juke, NV200 & X-Trail Etc.
One of these vehicles’ most notorious weak points is the Front Wishbone Rear Bush, fitting arms with the OEM codes 54750 BA60A 54570 BB00A, 54570 EN002 , 54501 1KK0A
The original rubber bush is prone to tearing, debonding and premature failure, leaving vehicle owners with no option but to replace the entire wishbone – only to face the same problem again shortly after.
This is where our 12AN Polyurethane Bush steps in. Designed as a direct replacement for the troublesome OEM part, it eliminates the common failure points while maintaining factory comfort and improving handling!
Why Choose Our 12AN?
Void-Free Design: Unlike the original rubber bush, our 12AN is free from voids, so it cannot tear or deform under load.
Factory Comfort: The bush is engineered to retain the comfort levels of the original, ensuring no harshness is added to your drive.
Enhanced Handling: By sharpening the responsiveness of the suspension, the 12AN allows your car to drive as well as it was always meant to.
Longevity: Made from our high-performance Polyurethane, it offers a fit-and-forget solution that outlasts rubber by 4-5 times over.Rerplc
An Accompanying Part: The 12AM Bush
12AM – Adjacent to 12AN, Replacing this bush will significantly reduce additional maintenance.
To complement the 12AN, we’ve also developed the 12AM Front Wishbone Front Bush. By replacing both bushes when removing the wishbone, you’ll complete an upgrade that eliminates the rubber’s weak points and ensures long-term reliability.
Why Rubber Falls Short
Rubber has long been the material of choice for suspension bushes in mass-produced vehicles due to its low cost and ease of manufacturing. But, it comes with significant drawbacks:
Degradation: Rubber deteriorates over time due to exposure to heat, UV light, and contaminants such as oil and salt.
Tearing: The voids designed into rubber bushes for comfort also make them prone to tearing under stress.
Short Lifespan: Frequent replacements are often necessary, which leads to increased maintenance costs and downtime.
The Polyurethane Advantage
Our Polyurethane bushes are purpose-built to overcome these issues. Here’s why they’re the superior choice:
Durability: Polyurethane is highly resistant to wear, UV degradation, and chemical exposure, giving it a lifespan measured in decades rather than years.
Performance: Its firmer yet flexible composition improves suspension geometry and vehicle handling without compromising ride comfort.
Cost-Effective: While the initial investment may be higher, the long service life of Polyurethane bushes means significant savings over time.
Fit and Forget
The 12AM & 12AN fitted to the Juke wishbone. A fit-and-forget solution.
At Polybush, we aim to provide suspension solutions that enhance the driving experience. With our 12AN and 12AM bushes, you can stop the endless cycle of replacing subpar components and enjoy a worry-free drive for years to come.
