SPL Parts PRO Solid Aluminum Differential Mounting Bushings (SDB) eliminate the stock mushy rubber bushings to hold the differential solidly to the subframe, preventing the differential from "bouncing around" under hard launches/acceleration. This will help prevent damage the drive shaft and half shafts, reduce wheel hop, and improve power transfer to the ground.Our Bushings are precision CNC machined from 6061-T6 Billet Aluminum for an accurate fit. This kit includes both the bushings on the front of the differential pumpkin as well as the bushings on the subframe where the rear of the differential mounts to. Sold as complete kit for one car. Made in the USA.
