Powerflex PFR5-4625 Rear Diff Front Mount Bushes for BMW X3 E83 2003-2010 - Polyurethane Differential Bushing Kit Pair | Rear Final Drive Front Bush Set | OE Replacement Upgrade 2pcs

PFR5-4625 Polyurethane Bushing Set for BMW X3 E83 2003 to 2010

Restore precision and eliminate unwanted movement at the front position of the rear final drive on your first generation BMW X3 E83 with this Powerflex PFR5-4625 upgrade. These uprated polyurethane bushes control diff torque reaction, reduce slack in the driveline and keep the rear axle geometry consistent for a more planted, confidence-inspiring feel on British roads and fast B-road driving.

Swapping tired factory rubber for Powerflex polyurethane delivers sharper response, improved traction out of corners and more predictable behaviour under braking and acceleration. Expect tighter turn in, reduced wheel hop and better use of your tyres in all conditions.
