Rear Differential mount bushing inserts - Ford Mustang S550

Important Notes: Inserts - installs into voiding of OEM bushing

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.
