034Motorsport Billet Aluminum Rear Differential Carrier Mount Insert Upgrade

For owners of the B8 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5, C7 Audi A6/S6/RS6, A7/S7/RS7, and D4 Audi A8/S8, the 034Motorsport Billet Aluminum Rear Differential Carrier Mount Insert is a game changer. If you've ever felt that unsettling slop or clunk when accelerating or shifting, you’re not alone. The factory rear differential carrier bushings feature rubber damping that can lead to excessive movement under load, resulting in a less-than-ideal driving experience.

These precision-engineered billet aluminum inserts are specifically designed to fill those voids in the factory mounts. This upgrade dramatically reduces rear differential movement, providing a more connected feel between your drivetrain and the road. You’ll notice crisper shifts and smoother throttle transitions without sacrificing ride quality or introducing unwanted noise, vibration, or harshness into your cabin.

Installation Made Easy

Worried about installation? Don’t be! This upgrade can be completed in just a few minutes and is entirely reversible, making it a hassle-free enhancement for your vehicle.
