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 Michelotti-styled TR4 modernised the range with a wider body and rack-and-pinion steering, but under the skin the early cars kept the familiar separate chassis and a leaf-sprung live rear axle. On a 1961 to 1965 TR4 the rubber suspension bushes have long since perished, leaving vague steering and a loose, dated feel.
Up front the top wishbone bushes wear and take the edge off the new rack-and-pinion steering, while the conical shock bushes harden. The live rear axle relies on its spring and shackle bushes to stay put; as they collapse the axle tramps and the ride suffers. Tired steering rack mounts round off the imprecision.
Fitting polyurethane suspension bushes to a Triumph TR4 sharpens the steering and settles the rear, and they shrug off oil and salt far better than rubber. The independent-rear car that followed is the TR4A, while the earlier TR3 shares this layout, or see the full Triumph range.
