BMW E39 Rear Differential Bushings Sedan – Polyurethane

Description

High-performance polyurethane rear differential bushings designed to replace OEM rubber mounts for improved drivetrain stability, reduced driveline movement, and more direct power transfer on the BMW E39 chassis.

These bushings significantly reduce differential movement under acceleration, braking, and load changes, helping to minimize wheel hop, driveline lash, and unwanted rear-end play. The result is improved throttle response, better traction, and a more connected driving feel—especially noticeable during spirited street driving or track use.

Available in two hardness options:

• 70 Sh (street / daily) – Balanced upgrade providing improved control while maintaining acceptable comfort and reduced noise and vibration for daily driving.

• 90 Sh (track / drift) – Maximum stiffness for minimal differential deflection under high torque loads, ideal for aggressive driving, track use, or motorsport applications.
