We're proud to announce the availability of our new Density Line Engine Mounts for the B8 Audi S5/RS5 4.2L FSI V8!

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:

034Motorsport Street Density Engine Mounts are manufactured from 65 durometer rubber, which is a significant upgrade from the 45 durometer rubber used in stock B8 Audi S5/RS5 mounts. Since the mounts are also void-free and solid-filled, the resulting mount is substantially stiffer than stock, without introducing any additional noise, vibration, or harshness into the cabin. The mount bodies are made from high quality cast aluminum using OEM production techniques.

The result is greatly reduced drivetrain slop, crisper shifting, and minimal wheel hop, without any noticeable increase in noise, vibration, or harshness (NVH) inside of the cabin. The solid rubber, void-free and fluid-free design eliminates the possibility of leakage and collapse, which is a very common issue with factory mounts. These mounts are a completely re-engineered performance solution, not just inserts for use with the factory mounts. They were tested thoroughly in-house at 034Motorsport, JH Motorsports, and by fellow Audi enthusiasts before release.

Factory Active Mount Emulators:

034Motorsport Street Density Engine Mounts utilize emulators to replicate the electronics of the factory engine mounts for plug-and-play installation. This ensures MIL-free operation for cars equipped with active engine mounts.

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.

Density Line Drivetrain Mount Lifetime Warranty:

034Motorsport is proud to offer a Lifetime Warranty on all Density Line Engine & Transmission Mounts - a true testament to the engineering & quality of our Engine Mount products. If you're reading this, it means this product is covered!

Whether you’ve purchased through 034Motorsport or one of our Authorized Dealers, your Density Line Drivetrain Mounts are covered by this Limited Lifetime Warranty. When you think your mounts need replacement or have experienced a mount failure, simply reach out to the 034Motorsport Technical Support team at [email protected]!

The 034Motorsport Density Line Drivetrain Mount Lifetime Warranty covers all Density Line Engine & Transmission Mounts with normal wear & tear or manufacturing defects. Engine & Transmission mounts that exhibit minimal wear, signs of abuse, or that were not installed properly may not be covered. While we want all customers to be able to take advantage of the Lifetime Warranty, those who abuse the Density Line Lifetime Replacement Warranty or act in bad faith may be disqualified at our sole discretion. We want to ensure that this Program remains fair and accessible to all customers.
