Question about this product?

We're happy to help.

The MMX Performance Rear Differential Raised Poly Bush is a two-position differential mounting bush engineered for the BMW G87 M2, G80 / G81 M3, and G82 / G83 M4. Developed as a direct replacement for the factory rear differential mounting bush, the MMX design can be installed at either the factory differential height or in a +10mm raised position, allowing the same component to support both standard-height and lowered G8X applications.

At the OEM-height position, the polyurethane bush creates a more controlled connection between the rear differential and chassis, reducing unwanted differential movement under acceleration and changing drivetrain loads. For lowered vehicles, positioning the center section at +10mm raises the rear differential mounting point to help restore driveshaft geometry altered by the reduced ride height. This reduces operating angle, heat buildup, and premature wear on the axle shafts and CV joints.

The raised bush is designed as part of the complete MMX Performance G8X differential mounting system. It can be paired with the MMX Front Differential Lift Mount / Cradle (MMR55-1604) for a 3-point configuration, or used with a second rear bush and the MMX Dual Differential Mount (MMR55-1606) to create a full 4-point differential mounting system.
