SPL Parts machines these differential mount bushings from 6061-T6 billet aluminum to replace the factory silicone filled rubber mounts, which are known to tear and weep under hard use. Going solid stops the differential moving under load, which cuts wheel hop, sharpens throttle response on corner exit and reduces the shock loads that break driveshafts and half shafts. The kit covers the bushings at the front of the differential pumpkin and the bushing in the subframe where the rear of the differential mounts, and it ships with a bushing driver tool for pressing the stock bushing out of the subframe. Made in the USA.
