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 MK5 (2011–2014) remains a popular vehicle for minibus operators, school transport services, council fleets and specialist passenger transport providers. Designed for durability, these vehicles frequently operate in demanding environments with high mileage, heavy loads and stop-start urban routes.
Over time, the original rubber suspension bushes can wear prematurely, particularly on vehicles used for school runs, shuttle buses and community transport. Worn bushes can cause excessive suspension movement, increased vibration, knocking noises and uneven tyre wear, all of which impact vehicle comfort and maintenance costs.
Polybush polyurethane suspension bushes are engineered as a direct replacement for the factory rubber components. Designed to offer superior durability and improved suspension control, Polybush bushes help maintain consistent handling and reduce the frequency of suspension repairs.
For fleet operators and council workshops, upgrading to Polybush suspension bushes for the Iveco Daily MK5 provides a reliable solution designed to cope with the demands of modern passenger transport fleets.
