The stock rubber bushings have voids to allow the differential to move around which translates to wheel hop under hard acceleration. By filling these voids it reduces wheel hop and improves overall handling of your car without adding any noise, vibration or harshness to the ride.

These give you the tightest cleanest install and fit to ensure your read end is locked solidly in place.
