034Motorsport is proud to offer the Apikol Polyurethane Rear Differential Mount Insert Upgrade for the B8 Audi A4/S4/RS4 and A5/S5/RS5! The factory Audi rear differential mounts have 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 polyurethane inserts are designed to fill the voids in the factory differential mounts, 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, this insert 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.
Polyurethane Construction Available in Soft (Blue) or Firm (Red)
