We're proud to announce the availability of the Density Line Transmission Mounts for B5 and C5 Chassis Audi and B5 Chassis Volkswagen models!
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.
The Street Density Transmission Mount is manufactured from 50 durometer rubber, which is approximately 20% stiffer than stock. The mount bases are made from steel, and are much stronger than the factory aluminum ones, to cope with the added stress of spirited driving.
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.
The Track Density Transmission Mount is manufactured from 80 durometer rubber, which is approximately 90% stiffer than stock. The mount bases are made from steel, and are much stronger than the factory aluminum ones, to cope with the added stress of spirited driving.
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.

High-Durometer Rubber vs. Polyurethane
Density Line Mounts are manufactured from high-durometer rubber instead of polyurethane for a number of reasons. While vulcanized rubber mounts are more expensive to prototype due to increased complexity of manufacturing and high initial tooling costs, rubber is inherently better than polyurethane as a damping medium for mounts and bushings.
Rubber is able to deal with stress under both tension and compression, while polyurethane mounts rely on the damping medium to be effective only under compression. Rubber is also excellent in shear, where polyurethane is ineffective, making it ideal for applications that apply a shear force to the bushing during articulation.
Rubber does not pack and wear like polyurethane does, which ultimately results in a long-lasting part with consistent performance and comfort.
Street Density vs. Track Density
We recommend Street Density Mounts for all daily-driven vehicles. They offer a significant increase in performance with a minimal increase in NVH transfer into the cabin. Track Density Mounts are recommended for purpose-built track cars, or those who do not mind significantly increased drivetrain noise and vibration in the cabin.
Please select Street Density or Track Density from the dropdown menu above.
Sold individually. One vehicle will require 1 or 2 mounts depending on application!
