MMX Aluminum Insert for OEM Rear Diff Bushing (Dual Mount) - BMW G8X

The MMX Performance Rear Differential OEM Bushing Aluminum Insert (MMR55-1619) completes the MMX insert system for the BMW G87 M2, G80 M3 Sedan, G81 M3 Touring, G82 M4 Coupe and G83 M4 Convertible running the MMX Dual Differential Mount, including applicable rear-wheel-drive and xDrive models. The MMX Dual Differential Mount (MMR55-1606) adds a second rear mounting point to the differential, which will require a second OEM rubber bushing as well as one of these individual inserts to fit that second bushing, matching the support provided by the MMX Rear Differential OEM Bushing Aluminum Insert Kit - Single Rear Mount (MMR55-1618) across both rear mounts. CNC-machined from 6061-T6 billet aluminum, the insert fills the voids in the factory rubber bushing to limit differential movement while the OEM bushing stays in place.

Fits: BMW S58: M3 (G80/G81), M4 (G82/G83), M2 (G87). Confirm your exact car with us before ordering.
