PFF5-4601 bush fits both E46 & Z4 models, covering both 60 and 66mm size options. The E46/z4  front control arm bushes are known point of periodic failure, especially with lowered or hard used examples. Powerflex developed this polyurethane replacement, available in either standard Powerflex material or harder ‘Black Series’ material, intended for track use. This minimises lower arm deflection, delivering more consistent geometry while offering compliance for road and track comfort.

66mm housing fitted to E46s after approx. Feb 2001 and all Z4. For E46 before approx. Feb 2001, you will require the 60mm version. If your car was built around Feb 2001, please measure prior to ordering.

Part number 1 on diagram. One pair required per vehicle. Covered under Powerflex’s lifetime warranty. Please select material when ordering.
