Powerflex PFR5-712 Polyurethane Rear Upper Control Arm Inner Bush Pair for BMW E60 5 Series and E60 M5

Give your BMW E60 rear end the precision it deserves with this Powerflex polyurethane bush kit for the inner pivot of the rear upper arm. Designed as a direct replacement for the factory rubber items, these uprated bushes sharpen chassis response, keep your geometry consistent under load and help the car put power down cleanly. Ideal for fast-road use and spirited driving where stability and confidence are key.

We run these ourselves and customer feedback has been outstanding. Expect a tighter, more planted feel at the back of the car with improved cornering confidence and far better control during hard acceleration and braking.

Key advantages

• Locks in rear axle geometry for crisper steering reactions and predictable balance
• Reduces unwanted arm movement for a more connected, confidence-inspiring drive
• Helps minimise irregular tyre wear by maintaining camber and toe more consistently
• High-grade polyurethane resists oil, heat and ageing far better than standard rubber
• Engineered firmness that improves control while keeping refinement in check
• Backed by Powerflex Lifetime Warranty for long-term peace of mind

What is included

Sold as a pair. You receive 2 x inner bushes for the rear upper link.
