Powerflex PFR5-426 Rear Final Drive Rear Mount for BMW X1 E84 xDrive 2008 to 2015

Transform the way your BMW X1 E84 xDrive steers and puts power down with the Powerflex PFR5-426 rear final drive rear mount. This uprated polyurethane bushing replaces the tired factory rubber at the back of the differential, tightening up the rear end for cleaner traction, crisper response and confidence on British roads in all seasons. It is a smart, durable upgrade for daily use, spirited driving and fast-road setups.

• Locks down unwanted differential movement for consistent grip out of corners
• Improves steering precision and rear axle stability under acceleration and braking
• Polyurethane construction resists oil, salt and road grime far better than OE rubber
• Helps reduce wheel hop and driveline shunt for a more connected feel
• Excellent service life with low maintenance requirements

Why polyurethane

Unlike soft rubber mounts that soften and split with age, polyurethane maintains shape and stiffness for consistent geometry. It tolerates heat, fluids and road contaminants, helping protect your tyres and driveline while delivering precise control mile after mile.
