Powerflex Differential Dual-Mount Bushing & Bracket Set

Adding a second mounting point to the rear differential significantly improves differential support, chassis rigidity, and torque transfer while helping reduce stress and premature wear on the factory differential bushings. BMW originally included a provision for a second rear differential mounting point but ultimately left it unused from the factory. This Powerflex aluminum differential bracket is available as a complete kit with Powerflex performance bushings, converting the differential to a true dual-ear mounting system.

Powerflex Street (Purple) — Designed for street-driven BMW F8X applications, the Street bushing uses a full-urethane construction with a stainless-steel insert and offers performance improvements while maintaining NVH characteristics close to the OEM differential mount. Comfortable for everyday driving and includes a lifetime warranty.

Powerflex Track (Black) — Designed for dual-purpose street and track BMW builds, the Track bushing uses a significantly harder polyurethane compound for increased differential control and rigidity under aggressive driving conditions. The semi-rigid design helps minimize differential movement and improve power transfer while introducing more NVH than the Street compound.
