Powerflex Rear Upper Arm Inner Bushes (E36/E46 inc M3)
The E36 and E46’s rear end features a number of bushes which are easy to over look when it comes to upgrades. One of those is the upper and lower control arm bushes – Powerflex developed this polyurethane replacement which minimises control arm deflection, delivering more consistent geometry without disrupting compliance for road use.
Part number 17 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.
