Powerflex Rear Anti-Roll Bar Bushes 15mm (Pair) for BMW 1 Series F20 F21 xDrive AWD PFR5-1913-15 Polyurethane ARB/Sway Bar Bush Kit OE 33556853476

Powerflex Polyurethane Rear Stabiliser Bar Bushes 15 mm for BMW 1 Series F20 F21 xDrive AWD (Pair) — PFR5-1913-15

Dial in tighter, more predictable handling on your xDrive 1 Series with these high-performance polyurethane rear stabiliser bar mounts. By replacing tired factory rubber, this upgrade delivers a more planted back end, faster response to steering inputs and improved confidence on fast road and everyday driving. If you want a simple bolt-on that genuinely sharpens the chassis without spoiling ride quality, this is the one.

We run these bushes in-house and fit them for customers at MJ Modifications. The feedback is consistent: reduced body roll, cleaner turn-in and better grip when changing direction. It is a proven suspension upgrade for the F20 and F21 xDrive platform.
