034 Motorsports – Drivetrain Mounts. Fits Audi RS5 B9/B9.5, Audi S4 B9/B9.5, Audi S5 B9/B9.5.
For Audi owners looking to enhance their driving experience, the 034Motorsport Billet Aluminum Transmission Mount Insert is a must-have upgrade for your B9/B9.5 Audi A4/S4, A5/S5/RS5, Q5/SQ5, Allroad, C8 RS6/RS7, 4M.5 SQ7/SQ8, and D5 A8/S8. The factory transmission mount has a significant void in its rubber damping medium, leading to excessive movement under load. This slop can negatively affect your driving dynamics, causing a less responsive feel when accelerating, decelerating, and shifting.
This billet aluminum insert is engineered to fill that void, drastically reducing transmission movement without compromising ride quality or introducing unwanted noise and vibration into the cabin. By stabilizing the transmission, you ll enjoy crisper shifts and a smoother overall driving experience, whether you're on the highway or tackling twisty back roads.
Before hitting the market, this mount insert was rigorously tested on 034Motorsport's in-house B9 Audi A4 Development Vehicle and by independent Audi enthusiasts. The feedback was overwhelmingly positive, confirming that the insert effectively minimizes drivetrain slop while maintaining the refined comfort you expect from an Audi.
The OE bolts used to secure the transmission mount insert are one-time use torque to yield (TTY) bolts, which means they stretch and become unusable after installation. To ensure a reliable and durable setup, 034Motorsport provides new Grade 12.9 installation hardware that is stronger than the factory bolts, allowing for reuse. Just apply Blue Loctite and torque to 30nm for a secure fit.
Upgrade your Audi today with the 034Motorsport Billet Aluminum Transmission Mount Insert and experience the difference in performance and driving pleasure!
