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
With its silent powertrain and open-top driving, the Fiat 500e Convertible is one of the most relaxing city cars on the road — until the factory rear shock bushes (OEM 52140471, 52181828) begin to fail. When they do, expect rattles, clunks and a noticeably rougher ride.
Polybush’s 27V rear shock bush solves the problem permanently. Its polyurethane construction resists the wear and deformation that destroy rubber bushes, keeping your suspension tight and predictable. Once installed, it’s a genuine fit and forget solution — perfect for drivers who just want to enjoy every sunny mile.
Why choose Polybush over rubber?
Standard rubber bushes crack and deform over time, ruining the ride.
Polybush 27V maintains suspension alignment and comfort far longer than OEM parts.
Resistant to oil, fuel, water and road salt — ideal for year-round use.
Keeps the 500e Convertible feeling composed, quiet and fun to drive.
