Street Density Transmission Mount

The 034Motorsport Street Density Transmission Mount Upgrade is designed to enhance the performance of your Audi's factory transmission mount assembly. This high durometer rubber mount replacement directly upgrades the damping medium located at the rear of the transmission mount. By reducing slop and unwanted drivetrain movement during acceleration, deceleration, and shifting, this mount ensures crisper shifts and a more connected driving experience. Manufactured from 65 Durometer Rubber, this mount is engineered to work in conjunction with 034Motorsport's B8/B8.5 and B9 Audi Transmission Mount Inserts for maximum drivetrain control. The factory transmission mount's soft rubber can break down over time and lead to noticeable hesitation or lurching. This upgrade addresses that by limiting transmission movement, especially beneficial at increased power levels. It is a direct, drop-in replacement and is fully reversible. This mount upgrade allows you to reuse the factory cast portion of your transmission mount assembly, providing a cost-effective solution compared to replacing the entire assembly, which is often not available separately from dealerships. This transmission mount upgrade is compatible with various Audi models including the B8/B8.5 A4/S4/RS4, A5/S5/RS5, Q5/SQ5, and B9/B9.5 A4/S4/Allroad, Q5/SQ5. Specific part numbers for the factory assembly that this mount installs into include 8K0 399 151DB, 8K0 399 151CD, 8K0 399 151BF, 8W0 399 156AR, and 8W0 399 156AQ.
