Maximum Motorsports Rear IRS Urethane Differential Mounts w/ Tool
These urethane bushings for your 1999-04 Mustang Cobra are much stiffer than the original rubber yet are still compliant enough to dampen NVH (Noise, Vibration, and Harshness). Unlike many others who offer only the front differential bushings, Maximum Motorsports took the time and effort actually to analyze the IRS system. The MM Engineering Team realized that all of the differential bushings must be replaced as a set. The complete set includes the two front bushings and the essential single rear bushing. If only the front bushings are replaced and the original rubber rear bushing is left in place, a mismatch will be created in the stiffness of the bushing materials. The more rigid front bushings will deflect less, while the remaining rubber rear bushing will still deflect as much as ever. This in turn will increase the stress on the aluminum front mounting ears of the differential housing. The increased stress can lead to fatigue and stress cracking of the aluminum differential housing. Wheel hop will still be prevalent because the rubber rear bushing will deflect and allow the differential to flop around.
