Powerflex PFR5-1927 Rear Differential Front Mount Insert for BMW 3 Series xDrive

Rear Differential Front Mount Insert for BMW 3 Series xDrive F30 F31 F34 - Polyurethane - PFR5-1927

Transform the way your BMW 3 Series xDrive puts power down. This premium polyurethane front mount insert for the rear differential, part number PFR5-1927, fills the voids in the factory rubber mount to curb unwanted diff movement under load. Expect tighter traction out of corners, reduced driveline shunt during gear changes and a more connected rear end, all while keeping everyday refinement in check.

We use this upgrade on our own cars and customer builds, and feedback has been consistently excellent. It is a simple, effective drivetrain mount enhancement that makes your AWD 3 Series feel more precise on fast road driving without a harsh ride.
