At Polybush, we understand that reliable vehicle performance is essential, especially when your fleet’s efficiency is on the line. That’s why we’re proud to introduce the 39X Rear Axle Bush, the ultimate Polyurethane rear axle bush replacement that outperforms standard rubber bushes by up to 4-5 times in durability.

Why the 39X Rear Axle Bush is a Game-Changer for Rear Axle Bush Replacement

Many fleet operators and van owners have faced the frustrating reality of frequent rear axle bush failures. We were first approached by a local council facing constant issues with standard rubber bushes in their vans. Later, we partnered with Royal Mail to solve their recurring axle bush problems.

The Problem with Rubber Suspension Bushes

  • Degradation Over Time: Rubber tends to crack and wear out quickly under heavy loads and extreme temperatures.

  • Chemical and Oil Absorption: Exposure to oils, fuels, and road contaminants accelerates rubber degradation.

  • Bonding Failures: The bonding agents in traditional rubber bushes can weaken, causing the centre sleeve to de-bond from the outer casing, resulting in unwanted axle movement and unstable handling.

Why Polyurethane is Superior

Our Polyurethane 39X Rear Axle Bush offers a robust solution to these issues:

  • Exceptional Longevity: Polyurethane resists heat, UV, chemicals, and weather-related degradation, ensuring your vehicle’s rear axle bush lasts significantly longer.

  • Stable and Secure: Engineered to prevent de-bonding, our bush keeps the centre sleeve firmly in place, eliminating free movement that can lead to rear steering issues.

  • Consistent Performance: Unlike rubber, which can soften or harden with age, our Polyurethane bushes maintain their performance over time, ensuring reliable vehicle handling and road safety.
