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 Iveco Daily MK4 (2006–2011) with torsion bar front suspension is widely used in minibus fleets, community transport vehicles and commercial passenger services. While designed for heavy-duty applications, the standard rubber suspension bushes often wear prematurely under constant load.
Fleet operators commonly encounter front wishbone bush wear, anti-roll bar bush deterioration and suspension geometry movement, which can lead to steering instability and uneven tyre wear.
Polybush polyurethane suspension bushes offer a stronger and longer-lasting replacement for the factory rubber components. Designed for demanding fleet environments, Polybush bushes provide improved durability, better suspension control and reduced maintenance downtime.
Upgrading to Polybush bushes for the Iveco Daily MK4 torsion bar suspension helps fleet operators maintain reliable suspension performance on vehicles used for school transport, shuttle services and heavy-duty commercial work.
