Powerflex PFR5-716 Rear Outer Lower Integral/Control Arm Link Poly Bushes (Pair) for BMW E60 E61 5 Series, E63 E64 6 Series & X5 E53 – Polyurethane Polybush/Bushing Kit – Replaces OEM 33326770749 – Road Series

Powerflex PFR5-716 Rear Outer Integral Link Lower Arm Poly Bush Pair

Part number: PFR5-716

Refresh the rear end of your BMW with this genuine Powerflex Road Series upgrade. Designed for the rear outer bush on the lower integral link, this polyurethane pair replaces tired factory rubber, firming up the back axle for crisper response, improved stability and more consistent tyre contact. Ideal for daily use and fast-road driving, it is a direct-fit enhancement that keeps geometry in check under load and reduces unwanted movement in the rear link arm.

Why enthusiasts choose this upgrade

• Noticeably tighter rear-end control and more predictable handling
• Reduces bush compliance to help maintain alignment during cornering and braking
• Polyurethane construction for long-term durability versus ageing OE rubber
• Improves feel without sacrificing road manners
• Simple replacement for the standard bushing on the rear outer position of the lower integral link
