Product Details
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!
034Motorsport is proud to offer our Street Density Transmission Mount Upgrade for the B8/B8.5 Audi A4/S4/RS4 and A5/S5/RS5 & B9 Audi A4/S4/Allroad & Q5/SQ5! The factory Audi transmission mount assembly features a soft rubber damping medium, which allows for excessive transmission movement at increased power levels, and can break down over time. This movement can be observed as hesitation or lurching when accelerating, decelerating, and shifting.
This high durometer performance mount upgrade is designed to be a direct, drop-in replacement for the factory damping medium, and limit unwanted transmission movement. By reducing slop, this upgrade ensures that you're experiencing crisper shifts and a more connected driving experience. This upgrade will introduce some additional, perceivable increase in noise and vibration transfer into the cabin, especially on vehicles equipped with the Tiptronic transmission.
In addition, the factory transmission mount assembly components are not available separately from dealerships, and premature failure of this mount can result in having to buy the entire assembly. The Street Density Transmission Mount Upgrade from 034Motorsport lets you reuse the factory cast portion when replacing/upgrading the stock mount.
This mount was thoroughly tested by 034Motorsport, and independent Audi enthusiasts before release. Installation is very straightforward, and is completely reversible.

Amazing bit of rubber that transforms the car!
I was not 100% sure this would have much affect but after the installation my 2018 Audi SQ5 feels much tigher and responsive! Gone are the days of the yoyo effect upon manual shifting the gearbox and chassie is much tighter and feels more taught. I would recommend this 100% and am happy I was able to install the component in about 2 hours. It was a little bit of a challenge but after thinking about the best way to setup a transmission support jack it was relatively simple. A definate must buy for any B9 platform Audi!
