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
The TR4A brought a major change: Triumph fitted an independent rear suspension in place of the old live axle, and the car rode and handled far better for it. That sophistication depends on healthy bushes, and on a 1965 to 1967 TR4A the rubber has aged badly, so the improvement has quietly slipped away.
At the rear, the trailing arm bushes and the differential and axle mounting cups and cones do the work of keeping the wheels located; worn, they let the back squirm under power and braking. The radius arm bushes add to the movement, while up front the top and bottom wishbone bushes, the anti-roll bar and drop link bushes and the steering rack mounts blur the steering.
Our polyurethane suspension bushes restore the TR4A’s tidy, independent-rear handling and last far longer than rubber against oil and salt. The fuel-injected six that followed is the TR5/TR250, while the earlier live-axle car is the TR4, or browse the full Triumph range.
