We're proud to announce the availability of our Density Line Performance Differential/Transmission Mounts for most early Audi applications, including the B3 Audi 80/90/Coupe Quattro, Audi UrQuattro, Audi 4000/5000, Audi 100/200, and Audi S2/RS2!

034Motorsport's Density Line Mounts are the new standard in comfort and performance. Our mounts are redesigned with performance in mind, and manufactured from high-durometer rubber for increased performance and durability, without sacrificing comfort. Density Line Mounts are void-free and fluid-free, eliminating the slop associated with the factory mounts.

Street Density:

The Street Density Differential/Transmission Mount is manufactured from 50 durometer rubber, which is approximately 30% stiffer than stock.

The result is greatly reduced drivetrain slop, crisper shifting, and minimal wheel hop, without any significant increase in noise, vibration, or harshness (NVH) inside of the cabin. These mounts are a completely re-engineered performance solution, not just inserts for use with the factory mounts.

Track Density:

The Track Density Differential/Transmission Mount is manufactured from 80 durometer rubber, which is approximately 90% 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.

Features:

  • Manufactured from High Durometer Rubber
  • Includes New High-Grade Metric Hardware
  • Reduced Drivetrain Slop
  • Decreased Differential/Transmission Movement Under Load
  • More Direct Power Transfer
  • Improved Shifting Feel
  • Complete Drop-In Replacement of Factory Differential/Transmission Mounts
  • Sold Individually

Fitment:

  • B3 Audi 80/90/Coupe Quattro
  • Audi UrQuattro
  • Audi 4000/5000
  • Audi 100/200
  • Audi S2/RS2
    • Only replaces factory transmission mounts on later B4 chassis vehicles which use the B4/B5 style rear differential mounts.
Replaces:
  • 857 599 431 / 857599431
  • 431 399 151D / 431399151D

TOO SMALL
Size: Medium, Color: Blue
Nice socks, but they are way too small. Says they fit size 6 - 10. I kept 3 ( I wear size 8) and gave 3 to my daughter (size 8.5). We both agreed that they were just too small.
