Powerflex Front Radius Arm to Chassis Bush for BMW F20 F22 F30 F32 xDrive – PFF5-4101
Upgrade your BMW xDrive handling with the Powerflex Front Radius Arm to Chassis Bush. Engineered polyurethane bushes replace the soft, ageing rubber to deliver sharper steering, better braking stability and consistent geometry under load. This part features an offset bore machined into the sleeve to precisely match the offset of the original bush, retaining correct caster while dramatically reducing unwanted arm movement.
Ideal as a performance upgrade or OE replacement, these Powerflex bushes are a proven, durable solution for BMW F20, F21, F22, F23, F30, F31, F32, F33, F34 and F36 xDrive models including M135iX, M140iX, M235iX, M240iX, 335iX and 440iX. We’ve fitted these on our own cars and for many customers, with excellent feedback on steering response, precision and overall front-end confidence.
