The 034Motorsport Street Density B8/B8.5 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5 & B9 Audi A4/S4/Q5/SQ5 Transmission Mount Upgrade is designed to improve the performance of the factory transmission mount assembly with a high durometer rubber mount replacement. This part is a direct, drop-in upgrade for the factory rubber damping medium used at the rear of the transmission mount assembly. In conjunction with other 034Motorsport Drivetrain Mount Upgrades, the Density Line Transmission Mount further reduces unwanted drivetrain movement to ensure that you experience improved throttle response and more direct shifts.


Please Note: Installation of this upgrade will result in increased noise and vibration transmission into the cabin, especially in vehicles equipped with the Tiptronic transmission.


We highly recommend purchasing our Billet Aluminum B8 Transmission Mount Insert Upgrade along with this part to minimize unwanted drivetrain movement!
