Description
The Revshift polyurethane secondary differential bushing adds a second mounting point to the rear side of the differential on the BMW G80 / G82 / G83 / G87 – M4 / M3 / M2. This bushing must be used with a dual mount differential bracket. The oem differential will not mount to the secondary location without an aftermarket bracket. 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
