BMW E60 E61 E63 E64 Rear Final Drive Mount Poly Bush PFR5-726BLK

Looking to tighten up the rear end of your BMW 5 Series or 6 Series for serious performance driving? This uprated rear final drive mounting bush in the Black Series compound delivers the control and precision enthusiasts want from a polyurethane upgrade. Built for hard use with a 95 Shore A material, it keeps the differential securely located under load for crisper responses, cleaner power delivery and predictable handling on fast road, track day and competition builds.

Replace the ageing factory rubber insert and eliminate the sloppy movement that robs you of traction and consistency. We have fitted this exact bush to our own cars and customer vehicles, and the feedback is the same every time: noticeably firmer drivetrain control, improved stability on corner exit and better confidence when pushing on. If you are chasing lap times or want a more connected feel, this is a proven upgrade.

• High-durometer polyurethane for maximum location of the rear final drive
• Reduces axle tramp and wheel hop under hard acceleration
• Sharper throttle pickup and more direct shift feel
• Motorsport-focused compound for durability and consistent performance
• Direct-fit replacement for the original rear drive unit mount
