The factory Audi rear differential mount has voids in the rubber damping medium, which results in excessive rear differential movement under load. This movement allows for unwanted drivetrain slop (and sometimes clunks) that can be observed when accelerating, decelerating, and shifting.
These billet aluminum inserts are designed to fill the voids in both sides of the front-most factory B8 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5 & C7 Audi A6/S6/RS6, A7/S7/RS7 rear differential mount, and limit rear differential movement without sacrificing ride quality or introducing any additional noise, vibration, or harshness into the cabin. By filling the voids in the factory mounts, these inserts eliminate the associated slop and ensures that you're experiencing smoother shifting and throttle transitions, and an improved driving experience.
Installation is very simple, can be performed in minutes, and is completely reversible. These billet aluminum inserts are precision-machined to fill voids on both sides of the factory rear differential mount, and will not pack and wear out over time.
