Polybush Now Manufacturing Polaris Ranger Bushes

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.

Polybush Launches 49C Engine Stabiliser Bush for 2.2L Matra Murena – Performance Without Compromise

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.

49C_01 Web Polybush

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

Matra Murena - Engine Mount for 2.2L Vehicles 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.

Air Suspension Bushes for Citroën Relay, Fiat Ducato & Peugeot Boxer (2006-Onwards): Camper, Ambulance & Fleet Solutions

What suspension for my Ducato, Relay and Boxer

If you own or manage a Citroën Relay, Fiat Ducato, or Peugeot Boxer from 2006 onwards—especially one converted into a campervan, used as an ambulance, or operating as part of a fleet delivery service—you may already know that your air suspension setup differs from standard van models.

The good news? Polybush has you covered.

Worn Tyres asset - Web
Worn Bushes Will Also Cause Tyre Wear – Further increasing costs.

Whether you’re trying to eliminate annoying knocks and poor handling from worn bushes or save on costly full component replacements, our polyurethane air suspension bushes are the perfect solution.

Why Air Suspension Bushes Vary in Campers, Ambulances, and Delivery Vans

These vehicles often come equipped with factory or aftermarket air suspension systems to enhance ride comfort and handling under varying loads. However, this means they don’t use the same bush sizes or configurations as standard steel-sprung vans.

Because of this, many Citroën Relay, Fiat Ducato, and Peugeot Boxer owners struggle to find the right replacement bushes—especially if their vehicle was professionally converted for medical, leisure or commercial use.

Find the Right Bush – Use Our PDF Measurement Guide

4BN_01 Web Polybush

To help you identify the exact Polybush part you need, we’ve created a clear PDF guide with dimensions and images of each air suspension bush we offer for these platforms. All you need to do is:

  1. Measure your existing bushes or mounting points

  2. Compare the dimensions with our guide

  3. Get in touch with us for advice or to place your order

📥 [Download the Citroën Relay / Ducato / Boxer Air Suspension Bush Guide Here] 

Still unsure? Just drop us a photo and your measurements—we’re always happy to help.

Why Choose Polybush Over Rubber?

Whether you run a single campervan or a fleet of front-line ambulances, rubber just doesn’t last in high-load, high-use scenarios. Here’s why Polybush is the smarter choice:

  • Longer Lifespan – Polyurethane is resistant to wear, oils, UV, road salt, and varying conditions.

  • No Perishing or Cracking – Unlike rubber, Polybush doesn’t degrade .

  • Improved Stability – Tighter tolerances give better ride control and reduced body roll.

  • Cost-Efficient – Replace just the failed bushes rather than complete arms or air bag mounts.

Case Study: How We Helped an Ambulance Fleet Save Thousands

Ducato Ambulance - With Polybush Fitted

One of the UK’s regional ambulance services contacted us after struggling to source replacements for the failed air suspension bushes on their Fiat Ducato-based ambulances. The main dealer advised them to replace the entire mounting assembly, at a significant cost per vehicle.

After working with their maintenance team and reviewing measurements from our guide, we supplied only the specific polyurethane bushes that had worn—saving them from scrapping perfectly serviceable components.

Result? Thousands of pounds saved, less vehicle downtime, and longer-lasting performance.

Perfect for Campers, Ambulances and Fleet Delivery Vehicles

If your vehicle falls into one of the following categories, this applies to you:

  • ✅ Motorhome or Camper Conversion with air suspension

  • ✅ Ambulance or Patient Transport Service using Relay, Ducato or Boxer chassis

  • ✅ Delivery Fleet Vans with air-ride suspension kits fitted

  • ✅ Any modified suspension layout not using standard steel springs

Don’t gamble on generic parts or complete assemblies. With Polybush, you get precision-fit polyurethane bushes that are made in the UK and built to outperform rubber.

Solving MK4 MX5 Hub Bush Failure

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 in mx5life.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.

OE References: N243-26-11X, N243-26-11XA, N243-26-11XB, N243-26-12X, N243-26-12XA, N243-26-12XB, N243-34-300, N243-34-350

Rear Hub Diagram MX5 MK4 ND 27AL / Kit 210
We sell all MX5 MK4 (ND) Hub bushes separately

Why OEM Fails (But 27AL Doesn’t)

  1. 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 clunk forum.mx5oc.co.uk.

  2. No Spare Bush Supply
    Mazda doesn’t offer the spherical bushes separately, forcing you down the costly full‑hub route mx5life.com+2bofiracing.com+2mx5nutz.com+2mx5parts.co.uk+3forum.mx5oc.co.uk+3ebay.com+3.

  3. 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.

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.

Savvy Savings

  • Parts & labour DIY total ≈ £389 versus £1,600+ dealer job—a ~75% saving.

  • Even if you pay a trusted independent workshop £200 for fitting, your total budget is under £600 all in.

  • Alignment stays sharp, tyre wear is reduced, and your MX‑5’s handling remains crisp, not squirrely.

Alignment & Handling Even Better

Polyurethane bushes, especially 27AL, create a far tighter suspension geometry than worn spherical bearings. What do drivers notice?

  • No bounce or “clunk” coming out of corners or bumping over speed humps.

  • Sticky grip under acceleration and braking—less squat and roll.

  • Control maintained miles into misaligned OEM replacements.

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.

Q: Does it squeak like some polyurethane bushes?
A: No. Polybush’s comfort/blue kit is designed not to squeak—and installs handily with dish soap, as Michelin‑tested backers confirm.

Q: Is it DIYable?
A: Absolutely—it’s a weekend job for a mechanically‑minded owner. But a hydraulic press speeds things up.

Final Word

If you own an MX‑5 MK4 or RF, the rear hub bush/spherical bearing is a ticking time bomb. Mazda’s only fix is an expensive hub swap—but with Polybush’s 27AL it, you can:

  • Save around £1,000+ on parts and labour

  • Eliminate rear clunks and restore solid control

  • Keep alignment tighter for longer

  • Get top-tier, corrosion-resistant, long-lasting performance

We provide full fitting instructions, videos and expert backing. Thousands of happy customers— and even Mazda garages—have already chosen 27AL.

Don’t wait for the knock. Act now, fit 27AL, and enjoy your MX‑5 like it’s fresh out of the showroom.

L663 Vehicle Launch_ Parts List
,

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.

Say Goodbye to Premature Bush Failure

One of the most common points of failure on the modern Defender L663 is the front lower front arm bush, part of OE reference LR034219. Designed to replace a long list of OEM part numbers — LR034220, LR072468, LR072469, LR072470, LR072471, LR073463, LR073465, LR109038, LR109039, LR113306, LR113307, LR113702, LR113703, LR126101, LR126102 — our polyurethane Front Lower Front Arm Bush (Polybush Code: 1DU) is engineered to outperform the original rubber in every scenario.

L663 Vehicle Launch_ Main Failure Bush

Why Upgrade to Polybush on Your Defender?

Key Benefits of Our Defender L663 Bushes:

  • Direct replacement for LR113306 – fits without modification

  • Longer lasting than OEM rubber – no more premature wear

  • Improved handling and ride quality – perfect for daily driving and off-road

Stop the Downtime: Fit Polybush 55A to Your LEVC TX5 (TXE) and Keep Your Taxi Earning

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.

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.

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.

Don’t Let A Bush Cost You £1000s

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

Keep Your Taxi Earning. Fit Polybush.

The TX5 is a fantastic vehicle — modern, green, and built for the city. But like all vehicles, it’s only as strong as its weakest component. With Polybush 55A, you take that weak point and turn it into a strength.

Behind the Scenes at Polybush: LR Centre Visits Our UK Facility

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

  1. 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.

  2. 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.

  3. 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:

Material Difference - LR Live Video

GradeShore HardnessIdeal For
Performance85 ShAHigh-speed or towing.
Dynamic75 ShAEvery day, driving with a firmer feel
Comfort65 ShAStreet-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:

  1. Choose the Right Material
    Do you crave the compliance of rubber for classic cruising, or the precision of polyurethane for modern performance?

  2. 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.

Polybush 40BR Ford Fiesta Rear Axle Bush
,

How 40BR Solves Failing Rear Axle Bushes – Fiesta Mk7 ETC.

If you own a Mazda 2 (DE, DH) (2007-2015), Ford B-Max (JK) (2012-On), Ecosport (CBW) (2014-On), or a Fiesta Mk7 (CB1, CCN) – be it Non ST (2008-2017) or ST (2013-2017), you’ll know the frustration when your rear beam or rear axle bushes start to fail.

The OEM part numbers 1535296, 1751679, 1805815, 1805866, 1871475, 8V51-5K653-AA, AY11-5K653-AA are notorious for not living up to expectations, leaving many drivers dealing with constant repairs and a noticeably compromised ride.

The Dreaded Symptoms of Failing Rear Axle Bushes

Imagine driving your Fiesta, only to notice an unsettling looseness during the cornering. When the original rubber bushes fail, you typically experience symptoms such as excessive vibration, imprecise handling, and a general loss of feedback. The harsh reality is that your rubber bushes undergo stress daily – the plastic shell develops cracks, the rubber debonds from the tube, and the housing deteriorates. More than a mere inconvenience, a failing bush can lead to additional wear on other components, meaning more money is spent on repairs in the long run.

Why Polybush 40BR is the Best Choice

Now, imagine the transformation with the installation of the Polybush 40BR. Manufactured from premium polyurethane, this bush is engineered to withstand deflection and resist the natural wear and tear that plagues standard rubber. Here’s what you can expect:

  • Enhanced Driving Precision: With the voids removed from the original bush design, the 40BR offers a firmer connection between your chassis and axle. This means more precise handling through corners, improved grip, and overall better control of your Fiesta.

  • Retained Comfort: Despite its stiffer build, the design ensures that you still experience the original ride comfort of your car. Whether you’re just popping to the shops or pushing your Fiesta on the track, the upgrade benefits all driving styles.

  • Improved Tyre Life and Braking: By reducing unwanted deflection, your tyres experience less wear, and your braking system performs more reliably, making every journey feel secure and enjoyable.

One of its standout benefits is that there is no need to remove the axle from your Fiesta. A straightforward, hassle-free installation means you’re back on the road in no time, enjoying the improved handling and ride quality that your car deserves.

Simple, hassle-free installation that gets you back on the road quickly.

A Final Word

For those who value comfort, reliability, and longevity, switching to polyurethane is a no-brainer. With failing rear axle bushes causing all sorts of headaches on models like the Mazda 2, Ford B-Max, Ecosport, and Fiesta Mk7, why settle for a temporary fix with rubber? Instead, opt for a solution that lasts. As we like to say, “Fit it once, fit Polybush.”

So, if you’re ready to put an end to the recurring failures and the mounting repair bills, give the 40BR a try. It’s a godsend for both garages and vehicle owners alike—a true upgrade for your ride that combines expert engineering with the simplicity of a perfect fit.

39X - Product Release -_01 - Web

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.

Discovery 3 & 4 Polybush Upgrade: Performance, Durability & Comfort

You’re in the right place if you’re considering Polybush upgrades for your Land Rover Discovery 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.

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

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.
