Powerflex Black Series Rear Differential Mount Bush (Polyurethane 95A) for BMW M3 F80 S

Rear final drive mount upgrade for BMW M3 F80 — Part No. PFR5-4026BLK

Lock down your back axle for harder launches, cleaner gear changes and consistent traction. This premium polyurethane differential carrier bush is engineered to keep the rear unit located under load, cutting unwanted movement and helping to minimise wheel hop on fast road and circuit use.

• High-stability design with an integrated support washer to keep the final drive secure under acceleration
• Black 95A Shore polyurethane for maximum control and durability
• Black anodised 2011-T6 aluminium hardware for strength and long service life
• Reduces driveline deflection to improve traction, throttle response and repeatability
• Can be paired with the optional dual-mount rear differential bracket PFR5-4030 to run two bushes in the factory locations

We use this component in-house on customer builds and the feedback is exactly what keen drivers want: a tighter rear end feel, sharper launches and more confidence on power. If you are chasing improved hook-up, reduced axle tramp and a more connected drivetrain, this is the right upgrade.
