BMW M3 E46 Powerflex Rear Differential Front Mounting Bush

This Powerflex bush fits without modification as a direct replacement for the original bush fitted to the front mount of the rear differential on the BMW M3 E46. Manufactured from high-performance polyurethane, it reduces excessive differential movement during acceleration and gear changes, improving torque transfer to the wheels and reducing drivetrain thud, while retaining a level of comfort suitable for road use.
