Powerflex PFR5-725 Rear Differential Front Mount Bush Kit (Polyurethane) for BMW 5 Series E60 E61 & 6 Series E63 E64 xDrive - Final Drive Front Bushing Set - Replaces OEM 33176767525

Powerflex PFR5-725 Rear Final Drive Front Bush Set for BMW E60 E61 E63 E64

Transform the rear end of your BMW with the Powerflex PFR5-725 urethane front bushes for the rear final drive casing. This upgrade replaces soft factory rubber with tough polyurethane to control movement under load, cut axle tramp, and deliver cleaner power down on corner exit. A simple, proven improvement for 5 Series E60 E61 and 6 Series E63 E64 owners wanting sharper handling, better stability and a more connected feel without unwanted harshness.

We fit these on customer cars and the results speak for themselves. Tighter rear axle behaviour, reduced knock from worn mounts, improved traction in both wet and dry conditions and more confidence under acceleration and braking. Ideal as a performance upgrade or as a long-lasting replacement when the original mountings are perished or starting to clunk.

Why choose this kit

• Firmer support for the rear drive unit to limit fore and aft movement
• More consistent pinion angle for smoother drivetrain response
• Helps reduce wheel hop and axle tramp for improved grip
• Maintains rear geometry under load for predictable handling
• Oil, road salt and weather resistant polyurethane for durability
• Cost effective over time compared with repeatedly replacing rubber parts
