Powerflex BMW E81 E82 E9x Black Series Rear Upper Lateral Arm To Chassis Bush
Upgrade your BMW suspension with the Powerflex Black Series Rear Upper Lateral Arm to Chassis Bush. Engineered for track, race and rally, this high-performance polyurethane bush uses a 95 Shore compound to maximise control of rear suspension geometry, reduce deflection under load and deliver sharper turn-in, improved stability and consistent alignment on road and track.
Perfect replacement for tired factory rubber bushes, these Powerflex Black Series bushes offer precise handling, better traction and long-lasting durability. We have fitted these on our own builds and for many Nforcd customers, and the feedback is consistent: tighter rear-end control, more confidence in fast direction changes and a genuine step up in performance.
