Differential Bushing Set

The ECS Tuning Complete Performance Polyurethane Differential Bushing Set - 95A is designed for BMW E60 models, specifically fitting the 525i with M54 2.5L and N52 3.0L engines. This kit replaces the original soft factory rubber differential bushings, which are intended to absorb vibrations and provide comfort during normal driving. By upgrading to these stiffer polyurethane bushings, you can expect a more direct feel and improved performance characteristics for your vehicle's differential. The material used is 95A durometer polyurethane, a high-performance compound that balances durability with the necessary flex for differential movement.
