Powerflex PFR5-412 Polyurethane Rear Upper Control Arm to Hub/Knuckle Bushings/Bushes (Pair) for BMW

BMW E9x xDrive Rear Wheel Carrier Bush Kit | Powerflex PFR5-412

Restore precision to the back end of your 3 Series 4WD with the Powerflex PFR5-412 rear upper arm to wheel hub carrier bush kit. These high-grade urethane inserts replace tired factory rubber and lock in alignment under load, helping your BMW track straight, corner flatter and put power down cleanly. Ideal for anyone searching for rear wishbone bushes, rear camber link bushes, upper link to knuckle bushes or rear hub carrier bush replacements for the E90, E91, E92 and E93 xDrive platform.

We run these on our own builds and customer cars. Feedback is consistently positive: firmer rear axle control, cleaner turn-in, more confidence in fast direction changes and noticeably improved tyre wear after alignment. If your OEM bushes are cracking, squeaking or causing instability, this is the durable performance fix that lasts.

• Stiffer urethane construction minimises deflection at the upper link to wheel carrier joint for repeatable geometry
• Sharper handling feel with reduced rear-end float on both road and track
• Better camber and toe control for more even tyre contact and longer tyre life
