Powerflex Black Series Front Radius Arm to Chassis Bush PFF5-701BLK for BMW E60 E61 E63 E64 5 & 6 Series (2003-2010), inc M5 M6 Tension Strut/Thrust Arm/Front Lower Control Arm Rear Polyurethane, OEM 31126765992

Powerflex Black Series PFF5-701BLK Caster Arm Rear Mount Bushes for BMW E60 E61 E63 E64

Transform the front end feel of your BMW 5 Series and 6 Series with the Powerflex Black Series PFF5-701BLK. These high-durometer urethane bushes replace the soft, fluid filled factory mounts on the forward lower arms, keeping geometry locked in under braking and cornering. Expect crisper turn in, better stability at speed and a more connected steering response on road and track.

Engineered for serious performance, the Black Series 95 Shore A compound controls arm movement far better than the OE hydro bush it replaces, reducing wobble and tramlining while helping to cure brake shimmy commonly found on ageing E60 and E63 chassis.
