Billet Aluminum Rear Differential Mount Insert Kit, B9 Audi A4/S4 & Allroad




The 034Motorsport Billet Aluminum Rear Differential Mount Insert Kit for B9 Audi A4/S4 & Allroad is designed to limit movement in the factory rear differential mounts to maintain proper suspension geometry when cornering, and improve the responsiveness of the rear suspension and differential.

By filling small voids in the factory mounts, this insert set eliminates the associated slop to ensure that you experience a more refined, connected driving experience, especially when driving at the limit. These billet aluminum parts will not pack and wear over time, and offer a lasting performance improvement.
