Overview

The Powerflex PFR5-426 is a rear differential mount bushing made from polyurethane.

Show original supplier description
The Powerflex PFR5-426 is a polyurethane rear differential mount bushing engineered for street sport applications. A properly functioning differential mount is crucial for transferring power smoothly to the wheels while absorbing and dampening the torque and vibrations generated by the differential. Signs of a worn differential mount include noticeable clunking or banging noises during acceleration, deceleration, or gear changes, as well as excessive vibrations felt in the rear of the vehicle or cabin. Powerflex utilizes advanced polyurethane manufacturing techniques to produce high-performance automotive components. This bushing is compatible with a wide range of BMW models, including various E81, E82, E87, E88, E90, E91, E92, E93, F20, F21, F22, F30, F31, F32, F33, F34, and E84 X1 series vehicles. Specific fitment details include models from 2004 through 2020, covering a variety of engine types and drivetrain configurations (RWD and AWD).
