Whiteline Plus 14+ Ford Mustang GT500/S550 Rear Differential Mount Insert
Heavily voided OEM rubber differential bushings allow a significant amount of shudder and wheel hop during hard throttle acceleration. Using Whiteline's low compliance polymer bushing technology to control the differential pinion movement this insert kit positively locates the front and rear differential bushings restricting the ability for the differential to move around providing a more precise power delivery to the rear end without compromising NVH.
