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
Ford KA suspension is about as simple as it gets, and that is exactly why worn bushes are so obvious in one. The RB built from 1996 to 2008 sits on Fiesta Mk4 mechanicals in a very light body, and a light car has no mass to disguise slack. Every bit of movement in a perished bush arrives directly at the steering wheel.
The front wishbone uses two different bush diameters, 46mm at the front position and 53mm at the rear, so check which you need rather than ordering a pair. The rear bush resists the wheel being pushed backwards under braking and is almost always the one knocking; the front bush is the one that quietly ruins steering feel around the straight ahead. A 16mm anti roll bar bush controls roll. At the back, a 63mm beam bush locates the entire torsion beam axle, and a worn pair let the rear gain toe under load.
These are inexpensive parts with an immediate effect. See the later KA RU8, the Puma that shares this running gear, or the Ford range.
