Transmission Mount Upgrade, Street Density (034Motorsport) for B8 A4-S4-RS4 A5-S5-RS5 Q5-SQ5, B9, A4-S4 Q5-SQ5

SKU: 034-509-4025
JHMotorsports is proud to offer 034Motorsport's Street Density Transmission Mount Upgrade for the B8-B8.5 Audi A4-S4-RS4 and A5-S5-RS5! 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.

The 034Motorsport Street Density B8-B8.5 Audi A4-S4-RS4, A5-S5-RS5, 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.

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.

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

We highly recommend purchasing 034Motorsport's Billet Aluminum B8 Transmission Mount Insert Upgrade along with this part to minimize unwanted drivetrain movement! Go back one section to find this part!

What a difference!
I installed this with 034MotorSport's billet aluminum transmission mount insert/brace. The difference is amazing. Before the car would jolt around when letting off the throttle, or rock a bit. When putting the pedal down, you'd feel the car hesitate before responding to it as well. Not only is my ride over-all much smoother now, but it shifts much nicer over all and reacts like a sports car should. I'm still in the break-in period, and there is practically zero noticeable NVH added. What I did notice was a very, very slight hint of added transmission whine, as well as some slight added vibration at sub 1,500 RPM's, but other than that it's flawless. Strongly recommended.
