So, why choose polyurethane over traditional rubber?
Durability: Polyurethane is renowned for its superior durability compared to rubber. It withstands harsh conditions, resists abrasion, and maintains its shape and performance over time. Say goodbye to premature wear and tear – these bushes are built to last.
Enhanced Stability: One of the key advantages of polyurethane is its ability to provide enhanced stability and control. By reducing flex and movement in the suspension system, these bushes contribute to a smoother, more responsive ride. You’ll notice improved handling and cornering, giving you greater confidence behind the wheel.
Reduced Noise and Vibration: Are you tired of the annoying squeaks and rattles that often accompany worn-out rubber bushes? Polybush offers excellent damping properties, effectively dampening noise and vibration. Enjoy a quieter, more comfortable ride, free from distractions.
Customizable Performance: Unlike rubber, polyurethane can be formulated to meet specific performance requirements. Our 40DE & 40DG bushes are designed to deliver optimal performance for Ford and Volvo vehicles, ensuring a perfect fit and seamless integration with your suspension system.
Installing Polybush 40DE & 40DG rear trailing arm bushes is more than just a maintenance task – it’s a longevity upgrade. Whether you’re tackling twisty backroads or cruising on the motorway, these bushes will enhance the performance, comfort, and longevity of your vehicle.
Whether you drive an Audi A3, VW Golf, SEAT Leon, or Škoda Octavia, you deserve a car that feels as tight, comfortable, and precise as the day it left the factory. Unfortunately, the front wishbone rear bush is one of the most common weak points in modern VW Group vehicles — and when it fails, you’ll feel it.
Perfect for daily drivers, family cars, and taxis, the 44EX – Front Wishbone Rear Bush restores confidence and handling while retaining the refinement you expect.
Why the Front Wishbone Rear Bush Fails
If your car’s started to feel vague on turn-in, clunky over bumps, or unstable under braking, there’s a good chance the culprit is the front wishbone rear bush.
OEM and aftermarket rubber bushes (VAG part numbers 1K0-407-183-P & 5Q0-407-183) tend to degrade quickly, softening and cracking under everyday conditions. Heat, oil, salt, and age all take their toll — causing premature failure.
The Polybush 44EX – Front Wishbone Rear Bush replaces the factory rubber bush with our specially formulated polyurethane compound, delivering the ideal blend of control, comfort, and durability.

Unlike harder performance bush kits, the 44EX – Front Wishbone Rear Bush is designed for real-world driving — it’s the perfect upgrade for commuters, families, and anyone who simply wants their car to handle properly again.
Key Benefits
Exceptional Longevity
Polyurethane doesn’t perish, crack, or absorb oil like rubber does. Polybush bushes last up to five times longer than OEM rubber alternatives, saving you time and money in the long run.
Comfort and Control Combined
We developed the 44EX – Front Wishbone Rear Bush specifically to maintain comfort. You’ll enjoy sharper handling and reduced body roll, without harshness or vibration inside the cabin.
Improved Handling & Steering Feel
A more consistent suspension setup gives you a more connected feel through the steering wheel. Expect more confidence during cornering, overtaking, and motorway cruising.
Safer, More Predictable Performance
Because the 44EX – Front Wishbone Rear Bush holds geometry better than rubber, you’ll benefit from improved braking stability, consistent wheel alignment, and better tyre wear.
Rubber bushes are fine when new — but they simply don’t last. Polyurethane provides a lasting, stable platform that protects your tyres, alignment, and confidence behind the wheel.
