Secondary Differential Bushing - BMW F80 / F82 / F83 / F87 - M4 / M3 / M2

$152.00

The Revshift polyurethane secondary differential bushing adds a second mounting point to the rear side of the differential on the BMW F80 / F82 / F83 / F87 - M4 / M3 / M2. This bushing must be used with a dual mount differential bracket. The oem differential bracket is not compatible. The goal of this secondary bushing is to reduce the movement of the differential under load. These bushings are a two piece design which securely holds the differential in place preventing it from sliding or twisting.

    • Improves handing
    • Will not wear out like oem bushings
    • Properly dampens the differential
    • Prevents differential from moving / twisting
    • Revshift bushing lube included

    Lifetime warranty
