Differential 90SH polyurethane bushings for BMW E8x, E9x not M models
Upgrade the rear suspension of your BMW by replacing the factory rubber differential carrier bushings with high-quality polyurethane units. These bushings significantly reduce unwanted flex and movement in the rear subframe area, resulting in improved stability, more consistent suspension geometry, and a more connected driving feel in both performance street and motorsport applications.
Engineered for durability, these bushings withstand heavy load cycles far better than standard rubber, reducing premature wear on surrounding components while maintaining precise alignment over time.
While these bushings provide enhanced stability and control, they may increase NVH slightly compared to factory rubber components. For best results, ensure surrounding differential and suspension mounts are in good condition prior to installation.
