034 Transmission Mount Upgrade, B8/B8.5/B9/B9.5 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5

Audi B8 and B9 transmission mount upgrade for improved shift feel and control

The 034Motorsport Street Density Transmission Mount Upgrade is designed for Audi B8 and B9 models where reducing drivetrain movement and improving overall driving feel is the goal. The factory mount uses soft rubber, which can allow excessive movement under higher power levels and degrade over time.

This upgrade features a higher durometer 65 rubber compound that limits unwanted transmission movement while maintaining reasonable comfort. The result is crisper shifts, improved throttle response, and a more connected driving experience, especially under spirited driving conditions.

This is a direct replacement for the factory damping medium and installs into the original mount assembly. It allows reuse of the factory cast housing, avoiding the need to replace the entire assembly as often required with OEM parts.

• 65 durometer rubber for improved control
• Reduces transmission movement during shifting and acceleration
• Improves shift feel and throttle response
• Direct fit into factory mount assembly
