Powerflex Rear Diff Rear Mounting Bush - BMW F8x M2/M3/M4

Powerflex Rear Diff Rear Mounting Bush

Upgrade the factory rubber diff mount with the Powerflex PFR5-4026 Rear Diff Rear Mounting Bush. This replacement bush features a built-in support washer for added stability of the differential under acceleration, reducing drivetrain deflection and the potential for wheel-hop during hard launches.

Made from Powerflex's signature Purple 80A durometer polyurethane with a Black anodised 2011-T6 aluminium housing, this bush is a direct, exact-fit replacement for the aged OE rubber mount. It can also be paired with our PFR5-4030 Dual-Mount Rear Differential Bracket to run two bushes across both factory mounting positions, for maximum differential control and a lasting fast-road or track setup.

Fitment: BMW F8x M2/M3/M4 (F80 M3, F82/F83 M4, F87 M2)
