Powerflex Black Series 30mm Rear Anti Roll Bar Bush for BMW F20 F21 F22 F23 F30 F31 F32 F33 F36 xDrive (Pair) | PFF5-1903-30BLK | Replaces 33356792196

Powerflex Black Series 30 mm Rear ARB Mount Bushings for BMW F-Series xDrive

Dial in rear-end grip and cornering confidence with these uprated 30 mm rear ARB mount bushes in the Powerflex Black Series compound. Built for serious performance, this motorsport-grade polyurethane dramatically reduces bar movement, keeps geometry stable under load and gives your BMW sharper response on fast road and track days. A straight swap for the factory rubber item that softens and wears, these hard-compound bushes help the car feel planted and predictable.

Part number: PFF5-1903-30BLK

OE reference: 33356792196

Size: 30 mm rear bar. Please measure your rear anti-roll bar diameter before ordering.

Why this upgrade

• Maximises rear roll control for crisper turn-in and flatter cornering
• Reduces deflection compared with OE rubber for consistent alignment and traction
• Polyurethane performance compound designed for hard use and repeatable results
• Direct replacement for the rear bar mounting bush, no fabrication required
• Ideal for fast road, track day, sprint and race builds

At MJ Modifications we have fitted these on our own cars and many customer vehicles, and the feedback is the same every time: noticeably tighter rear axle control, better stability on quick direction changes and improved confidence when pushing on.
