Powerflex BMW F8X M2 M3 M4 Dual-Mount Rear Differential Bracket Kit With Bushes

Upgrade the rear drivetrain stability of your BMW F8X M2, M3 or M4 with the Powerflex Dual-Mount Rear Differential Bracket Kit with Bushes (PFR5-4030). Engineered to eliminate the weakness of the factory single rear differential mounting point, this premium kit adds a second mounting location to significantly reduce differential movement under hard acceleration and aggressive driving.

Manufactured from high-strength CNC-machined 6082 aluminium with a durable satin black anodised finish, the dual-mount bracket is designed to withstand high torque loads while maintaining precise differential alignment. Combined with Powerflex polyurethane bushes, the kit delivers improved drivetrain control, sharper throttle response, reduced wheel hop, and a more consistent feel during on/off throttle transitions. These improvements make it an ideal upgrade for fast road, track day, and high-performance tuned vehicles.

Benefits

By utilising the unused second mounting point in the factory subframe, the Powerflex Dual-Mount Rear Differential Bracket distributes drivetrain loads more evenly, reducing stress on the differential bushes and helping to prevent premature wear. The result is a more planted rear end, improved power delivery to the road, and increased driver confidence during spirited driving or motorsport use.
