Powerflex Black Series Rear Anti-Roll Bar Bush 13mm for BMW F20 F21 F22 F23 F30 F31 F32 F33 F36 xDrive. The ultimate motorsport-grade polyurethane bush for sharper handling, stability and control. If you are searching for BMW rear anti roll bar bushes, rear ARB bushes, rear sway bar bushes, stabiliser bar bushes, BMW polyurethane bushes or performance poly bushes for F-series xDrive models, this Black Series upgrade delivers precise chassis control and repeatable performance on road, track, race and rally.
Engineered from a 95 Shore A polyurethane compound, the Powerflex Black Series minimises deflection and keeps the rear anti-roll bar working exactly as intended. Expect crisper turn-in, flatter cornering and more confidence under load.
