Rear Differential Mount

The Apikol Rear Differential Mount is engineered to replace the stock, "spongy" rubber mount in B6/B7 Audi A4, S4, and RS4 models, as well as C6 Audi A6 vehicles. Constructed from a high-strength cast aluminum alloy and featuring custom-molded polyurethane bushings, this mount significantly reduces excessive rear differential movement. This upgrade is ideal for addressing the "dreaded rear diff clunk" that can occur during aggressive shifting or acceleration. Users report a much tighter and more positive drivetrain feel, leading to cleaner launches and more predictable shifts, especially under hard driving conditions. The "street density" urethane offers a substantial improvement over the factory "sponge-like" rubber without introducing excessive noise, vibration, or harshness (NVH). Installation is straightforward and typically takes between 15 to 30 minutes, involving the removal of only four bolts and one nut. It is a direct swap and bolt-on part. The Apikol Rear Differential Mount is compatible with the following Audi models: - B6 A4 Quattro (2002-2005) - B7 A4 Quattro (2005.5-2008) - B6 S4 (2003-2005) with 4.2L V8 40v engine - B7 S4 (2005.5-2009) with 4.2L V8 40v engine - B7 RS4 (2006-2009) with 4.2L V8 32v FSI engine - C6 A6 (2005-2011)
