The E36 and E46 chassis’ share very similar layouts and both have the same inherent problems – one of these is poor rear trailing arm bushing life especially on lowered and/or hard-used examples. Powerflex developed this polyurethane replacement – this minimises trailing arm deflection, delivering more consistent geometry while offering compliance for road and track comfort.

Part number 3 on diagram. Priced per pair – one pair required per vehicle. Covered under Powerflex’s lifetime warranty. Please note that this part is only available in the Black Series material but can be packaged as either Road Series or Black Series.
