Powerflex Black Series Polyurethane Rear Outer Integral Link Lower Bush / Rear Lower Control Arm Outer Bush for BMW 5 Series E60 E61, 6

Powerflex PFR5-716BLK Rear Hub Outer Arm Bushing Upgrade for BMW E60 E61 E63 E64 and X5 E53

Unlock tighter rear-end control and rock-solid stability with the Black Series by Powerflex. Part number PFR5-716BLK replaces the outer joint on the lower rear arm at the wheel carrier, delivering a precise, motorsport-grade feel on fast road, track day and competition builds. The 95A durometer poly bush dramatically reduces flex compared with ageing rubber, keeping alignment true under hard acceleration, heavy braking and high-speed cornering.

We run these bushes on customer cars and the feedback is consistently excellent: crisper turn-in, better traction on exit and a calmer, more predictable rear axle. If you are chasing consistent geometry and long-term durability, this is the proven upgrade.

Key benefits

• Stiffer rear axle location for sharper response and predictable handling
• Maintains toe and camber under load for confident road and circuit driving
• High-resilience polyurethane resists oil, salt and heat far better than rubber
• Direct-fit replacement for the factory bushing with performance-focused compliance
• Track-proven compound for repeatable performance lap after lap
