Powerflex PFR5-4617 Polyurethane Rear Upper Control Arm Inner Bush Kit for BMW E46 3 Series M3 (2 Bushes) OEM 33321092247

PFR5-4617 Polyurethane Rear Upper Arm Inner Bushing Set for BMW M3 E46

Give your E46 M3 the rear-end composure it deserves with this uprated polyurethane bushing set for the upper rear wishbone inner mounting point. Part number PFR5-4617 replaces tired factory rubber at the inner joint of the rear upper suspension arm, tightening up rear axle geometry for sharper turn-in, predictable grip and repeatable alignment under load.

If you are chasing a precise rear end on fast road or track, these poly bushes stabilise camber and toe, reduce unwanted flex and help the tyres maintain a stronger contact patch. The result is crisper responses, improved traction out of bends and greater confidence when braking hard or changing direction.

Key advantages

• Uprated polyurethane resists deformation, oil and heat far better than ageing rubber
• Helps control camber and toe movement for stable alignment and consistent handling
• Improves braking stability, cornering accuracy and rear-end traction
• Durable, long-life solution that can reduce tyre wear and maintenance costs
• Backed by the Powerflex Lifetime Warranty for peace of mind
