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
Seat Leon Mk 4 rear axle bushes fit the KL1 and KL8 cars built from 2019 with a torsion beam rear end, which is what most of the smaller engined hatchbacks and a good number of Sportstourers left the factory with. One large bush per side locates the entire axle, so it is a quick job with a noticeable result.
On an estate in particular that bush leads a hard life. A Sportstourer carrying a full boot loads the rear axle far more than the hatchback does, and the mount has to hold toe and camber steady while absorbing everything the road sends up. Even on a relatively young car, owners chasing a knock over expansion joints or a rear end that feels slightly unsettled on a loaded motorway run usually find the answer here rather than in the dampers.
The front is the familiar arrangement of wishbone front and rear bushes with anti roll bar bushes in 21.7mm, 23mm and 24mm, plus a rear track arm lower outer bush. Compare the multi-link Mk 4, the Mk 3 rear axle, or the Seat range.
