Product Details
Material and Durability: Powerflex bushings are made from high-quality polyurethane, which lasts longer than the factory rubber bushings. This material resists wear from heat, oil, and harsh driving conditions, providing better long-term reliability.
Improved Stability: By reducing flex and movement in the rear differential, these bushings enhance power transfer and help maintain consistent alignment during acceleration and cornering. This translates to better handling and more predictable driving behavior.
Performance Versions: Powerflex offers different versions:
- Road Series: A balance between performance and comfort, designed for street use, with minimal increase in noise, vibration, and harshness (NVH).
- Black Series: A motorsport-oriented version made from stiffer polyurethane (95A durometer), offering maximum performance and control for track use, though it may slightly increase NVH.
Easy Installation: These bushings are direct replacements for the OEM rubber bushings, making installation straightforward. They help eliminate the common issue of worn-out factory bushings, which can lead to rear-end instability, clunking noises, and poor handling.
Enhanced Driving Feel: Upgrading to polyurethane diff bushings tightens up the rear-end feel of your BMW, giving you a more connected and responsive experience behind the wheel, especially during aggressive driving or hard launches.
Applications:
- BMW Z3
- BMW E30 3 Series
- BMW 318Ti (E36 Compact)
For those looking to restore or enhance their BMW’s rear-end stability while upgrading longevity, Powerflex bushings are a solid choice, whether for road or track use.
