Rear Differential Mount, Density Line, B2/B3 Audi UrQuattro, 4000, 80, 90, Coupe Quattro, Replaces 893 599 381
We're excited to announce the availability of our Track Density Performance Differential/Transmission Mounts for most early Audi applications, including the B3 Audi 80/90/Coupe Quattro, Audi UrQuattro, and Audi 4000 Quattro!
034Motorsport's Track Density Differential Mounts are the new standard in affordable drivetrain upgrades. Our mounts are redesigned with performance in mind, and manufactured from high-durometer rubber for increased performance and durability. Density Line Mounts are void-free, eliminating the slop associated with factory mounts.
The Track Density Differential Mount is manufactured from 80 durometer rubber, and is approximately 95% stiffer than stock.
The result is a locked-down drivetrain, solid shifting, and virtually no wheel hop. Track Density Mounts will cause a noticeable increase in noise, vibration, and harshness (NVH) inside of the cabin.
