Polyurethane Rear Upper Arm Outer Bushing Kit for BMW E46 E36 Z1 Z4 inc M3 and Z4M

Dial in razor-sharp rear axle control with this Powerflex Black Series rear upper arm outer bushing kit. Built in a 95 Shore A motorsport-grade compound, these poly bushes keep rear suspension geometry in check under load, cutting flex from tired factory rubber and giving you crisper turn-in, improved stability and repeatable handling lap after lap.

Perfect for fast road, track days, drift, time attack and club motorsport. We run these on our own builds and customers consistently report a tighter rear end, clearer feedback and greater confidence when pushing on.

Key benefits

• Ultra-stiff Black Series polyurethane for maximum control of camber and toe at the outer upper link
• Minimises unwanted movement compared to OEM rubber for more precise alignment retention
• Enhances rear-end grip, predictability and consistency under braking and cornering
• Direct swap for the factory outer bushing at the upper wishbone to hub carrier joint
• Durable, track-proven construction designed to perform in heat, load and abrasion
• Replaces BMW OE reference 33321092247
