Motor Mount, Density Line, B6/B7 Audi S4/RS4 V8 & C5 Audi A6/S6/RS6/Allroad 4.2L
Tired of unwanted engine movement under load and drivetrain slop when shifting? 034Motorsport's Density Line Motor Mounts for the B6/B7 Audi S4/RS4 & C5 Audi A6/S6/RS6/Allroad 4.2L are designed to provide improved performance over the factory mounts, as well as eliminate the failure-prone "Active Engine Mount" feature.
By replacing the voids and fluid cavities in the factory mounts with high-quality Density Line rubber, and manufacturing the mount bases from steel instead of aluminum, these mounts drastically reduce unwanted engine movement and eliminate most common failures of the factory mounts.
Please Note: Our Active Motor Mount Resistor Bypasses are sold separately, and are designed keep the check engine light off on vehicles equipped with Active Engine Mounts from the factory. Simply plug these in to the factory harness and go!
NVH Levels: Low - Medium

We are VERY excited to be announcing the release of our 034Motorsport Street Density motor mounts for the B6/B7 Audi S4/RS4 and C5 Audi A6/S6/RS6 and Allroad!
We've been testing these mounts for some time to ensure they are reliable and meet the criterion for the intended use - results so far are very exciting!
WHAT THEY ARE: A new line of rubber motor mounts made FOR us by OE suppliers to OUR specifications.
STREETDENSITY Mounts are solid rubber mounts with a 50 durometer about 10% stiffer than stock, this means they still ride smooth and quiet but provide a marked improvement in drivetrain dampening over stock mounts. Livable street performance with serious sport intentions. Note, since there are no voids or air pockets in these mounts, even though the rubber is only 10% stiffer, the resulting reduction in drivetrain movement is actually 25% stiffer.
THIS IS NOT AN OE MOUNT, OR AN RS4 MOUNT, AND THESE ARE NOT AVAILABLE FROM ANY OTHER SOURCE - These are built by an OE supplier to 034Motorsport specifications for performance applications.
Combine with Density transmission mount and 034Motorsport snub mount and cage for the ultimate in performance drivetrain mounting.
