This SuperPro differential mount bushing kit replaces the forward pinion mount bushings on 1965–1968 Triumph TR4A rear differentials. The OEM rubber units tend to soften and fail with use, allowing increased differential movement that affects responsiveness and can create noise and vibration. SuperPro’s upgraded bushings maintain cabin NVH isolation while improving differential location and service life under varied loads.
