Powerflex BMW E60 E61 E63 E64 Black Series Rear Upper Arm Inner Bush
Upgrade your BMW rear suspension with the Powerflex Black Series Rear Upper Arm Inner Bush, part number PFR5-712BLK. Designed for track, race and rally use, these 95 Shore polyurethane bushes deliver maximum control of chassis geometry for sharper handling, improved stability and consistent alignment. If you are chasing precision, durability and performance on your BMW 5 Series E60 E61 E61 xDrive or BMW 6 Series E63 E64, this is the proven rear upper arm inner bush upgrade you want.
Powerflex Black Series bushes replace the soft factory rubber bushings that flex under load, helping to reduce unwanted movement in the rear suspension. The result is tighter rear end control, more predictable cornering, better traction and confidence on fast road, track day and motorsport builds. We use Powerflex bushes on our own cars and our customers consistently report a noticeable transformation in feel, response and long term reliability.
