Powerflex PFR5-426 Rear Differential Rear Mount Bush for BMW X1 E84 (2008-2015) - Polyurethane Rear Axle Diff Mount/Bushing Upgrade, Differential Carrier Support/Hanger Replacement

Uprated Rear Axle Differential Mount Bush for BMW X1 E84 2008 to 2015 - Powerflex PFR5-426

Transform the back end control of your BMW X1 E84 with the Powerflex PFR5-426 rear axle differential mounting bush. This precision polyurethane bushing replaces the tired OE rubber insert to stabilise the driveline, sharpen response and deliver a more planted, confidence-inspiring drive in all conditions.

By limiting unwanted movement at the differential carrier, the PFR5-426 keeps the drivetrain aligned under hard acceleration, fast direction changes and heavy braking. Expect crisper turn-in, better traction out of bends and more consistent grip that helps reduce wheel hop and rear-end shimmy.
