UPR 15-18 Mustang IRS Differential Mount Bushings Red Energy
Energy Suspension's S550 Mustang Differential Mount Bushings are made from polyurethane, making them much more durable than OEM rubber mounts. Polyurethane is not only stiffer but is largely unaffected by contaminants and the weather, making it a much longer-lasting material.
The factory rubber differential mount bushings in the 2015-18 Mustang are designed for comfort, not performance. The soft bushings allow the differential to shift around when power is applied, promoting wheel hop and potentially damaging components. These polyurethane bushings from Energy Suspension are firm enough to keep the differential in place without significantly increasing NVH (Noise, Vibration & Harshness) over the sloppy factory bushings.
