We're proud to announce the availability of the Density Line Dogbone Mount Pair for MkV & MkVI Chassis Volkswagen and 8P & 8J Chassis Audi models!
034Motorsport's Density Line Mounts are the new standard in performance. 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 and fluid-free, eliminating the slop associated with the factory mount.
The Density Line Dogbone Mount Pair is manufactured from 60 durometer rubber, which is approximately 35% stiffer than stock. Since the mounts are also void-free and solid-filled, the resulting mount is approximately 85% stiffer than stock.
The result is greatly reduced drivetrain slop, crisper shifting, and minimal wheel hop, with a somewhat noticeable increase in noise, vibration, or harshness (NVH) inside of the cabin. (Please Note: NVH changes may be even more drastic in vehicles equipped with DSG or Tiptronic transmissions, and/or if your factory engine/transmission mounts are worn or failed.) These mounts are a completely re-engineered performance solution, not just inserts for use with the factory mount.
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 control arm bushings 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.
