BMW Rear Diff Rear Bushing - Powerflex Race PFR5-4626BLK

Upgrade your BMW's drivetrain with the Powerflex Race Black Series Rear Differential Rear Bushing (PFR5-4626BLK). Engineered for track, race, and aggressive street use, this high-performance polyurethane bushing drastically reduces unwanted differential movement, ensuring more direct power transfer to the wheels.

The OEM rubber bushing is prone to wear, causing "diff clunk," sloppy shifts, and diminished throttle response. Powerflex's Black Series material is a much firmer compound than their standard street bushings, virtually eliminating deflection under hard acceleration and braking. This results in a tighter, more responsive feel, enhancing the overall driving experience.

This single bushing replaces the rear-center-rearward differential mount on a wide range of E46 3-Series models (323i, 328i, 323Ci, 328Ci, 325i, 325Ci, 325xi, 330i, 330Ci, 330xi), as well as E85/E86 Z4 and E83 X3 models. Invest in superior durability and uncompromised performance for your BMW.
