Product Details

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 Engine Mount Pair is manufactured from 50 durometer rubber, which is approximately 10% stiffer than stock. Since the mounts are also void-free and solid-filled, the resulting mount is approximately 25% 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.

Features:

  • Manufactured from 50 Durometer (Street Density) Rubber with Void-Free Construction
  • Reduced Drivetrain Slop
  • Decreased Engine Movement Under Load
  • More Direct Power Transfer
  • Improved Shifting Feel
  • Complete Drop-In Replacement of Factory Engine Mounts
  • Sold Individually (One Vehicle Requires 2 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.

Please Note: The nuts for these mounts should be torqued to the factory specification of 25 Nm (approximately 18.5 ft. lbs.). Overtightening these nuts can cause damage to the mount!

Please Note: The 034 Active Motor Mount Resistor Bypasses are sold separately as ES2864610, and are designed keep the check engine light off on vehicles equipped with Active Engine Mounts from the factory. If your vehicle has active engine mounts from the factory, simply plug these in to the factory harness and go!
