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
Upgrade your Ford Fiesta Mk7 ST (CB1, CCN) (2013–2017) with Polybush front and rear suspension bushes, engineered to tackle the most common handling weakness on these cars – the rear axle bush (40BR).
Even on the Fiesta ST, the factory rubber rear axle bush is a known failure point. Under hard driving, fast road use or track work, the original bush allows excessive axle movement, dulling turn-in, upsetting stability under braking and accelerating rear tyre wear. Once worn, it quickly undermines the sharp chassis the ST is known for.
This Polybush rear axle bush is a direct replacement for the original Ford part and replaces the following OEM / OE references: AY11-5K653-AA, 8V51-5K653-AA, 1535296, 1751679, 1805815, 1805866, 1871475.
Manufactured from high-performance polyurethane, Polybush suspension bushes significantly reduce axle deflection while retaining compliance for road use. The result is tighter rear-end control, improved feedback and more confidence when pushing on, without introducing harshness or noise.
Designed to fit using the original mounting points, these bushes are suitable for DIY installation or professional fitting. Whether you’re refreshing tired suspension or sharpening the handling of your Fiesta ST, Polybush provides a durable, performance-led upgrade that keeps the rear axle exactly where it should be.
