Powerflex PFR5-426 Rear Final Drive Rear Mount Bushing for BMW 1 Series E81 E82 E87 E88

Give the back end of your BMW 1 Series the control it deserves. The Powerflex PFR5-426 polyurethane rear final drive rear mount bushing replaces the fatigued OE rubber at the rear-most differential support, tightening up the drivetrain and rear axle for a more planted, confidence-inspiring drive on road and fast B-roads.

By swapping out the soft, ageing rubber for a durable PU bushing, you reduce unwanted differential movement that can make the car feel loose under throttle, braking or mid-corner. Expect cleaner traction, steadier cornering and more predictable behaviour, all while maintaining excellent NVH manners for daily use.

  • Direct fit for BMW 1 Series E81, E82, E87, E88 at the rear position of the final drive assembly
  • Polyurethane construction for consistent support and long service life
  • Helps maintain alignment and tyre contact for improved grip and stability
  • Resists oil, road grime and weathering far better than standard rubber mounts
  • Ideal for spirited road driving and everyday commuting without harshness
  • Backed by the Powerflex Lifetime Warranty

We have fitted this part on customer cars and our own builds. Feedback is consistently positive: a more connected rear end, cleaner launch traction and a calmer, more precise feel from the chassis without unwanted noise or harshness.
