We’ve selected the material that offers the best balance of performance and comfort for your vehicle’s needs.
Our Comfort grade bushes are designed to enhance ride quality and minimise road noise, making them ideal for everyday driving. They are softer, providing maximum suspension articulation and a cushioned feel that absorbs bumps and vibrations effectively. This softer composition ensures a smoother, quieter driving experience, especially in Classic cars or Land Rovers. Comfort bushes maintain a balance between originality and ease of driving, catering to those who value a relaxed Factory-Fresh drive.
The Dynamic grade bushes offer a middle ground between Comfort and Performance. They are slightly firmer than the Comfort bushes, which improves handling and cornering response without sacrificing too much ride comfort. These bushes are ideal for drivers who enjoy a more engaging driving experience while still needing a level of comfort for daily use, whilst also being suitable for spirited driving & light track use.
Performance grade bushes are the stiffest of the three, designed for enthusiasts who demand the utmost in handling and control. They offer minimal deflection, enhancing vehicle response and stability during aggressive driving. These bushes are perfect for high-performance or track vehicles where precision and handling are critical. While they might sacrifice some ride comfort, they deliver superior driving dynamics and control, ideal for those who push their vehicle to its limits – Including Towing!
These rods are produced in 90 Shore A which allows them to be machined on a lathe.

Specifications
With the Discovery 3 and 4 (2004 to 2016) Land Rover switched to independent suspension and air springs, so the failure points moved from radius arms to the many control arm and subframe bushes that this heavier, more sophisticated setup relies on. As those bushes perish the Disco develops a clonk over speed bumps, uneven tyre wear, and steering that no longer feels planted, and an MOT tester will often flag play at the front lower arms first. It is a common issue on cars that tow or carry weight.
Polybush offers polyurethane replacements for the bushes that wear on the Discovery 3 and 4 chassis, giving a firmer, longer-lasting alternative to the original rubber that softens with age and heat. Fitting poly tightens up the steering, cuts the knocks, and restores the composed ride these vehicles are meant to have, without the price of complete new arms.
