Powerflex Rear Diff Rear Mounting Bush BMW 4 Series G22 G23 G82 G83 M4 20+PFR5-4026 is a replacement bush that features a built-in support washer, providing further stability of the diff under acceleration. PFR5-4026 can also be used in conjunction with our PFR5-4030 dual-mount rear differential bracket to mount two bushes into the factory positions. Made using our signature Black 95A durometer polyurethane and Black anodised 2011-T6 aluminium, to reduce drivetrain deflection and the potential for wheel-hop during hard launches. PFR5-4026 bushes can be fitted with our PFR5-4030 dual-mount rear differential.
