034 density line engine mounts, Audi A4 B5/B6/B7, A6 C5, Passat

Upgrade your Audi or Volkswagen with 034 Motorsport’s Density Line Motor Mounts – the new benchmark in comfort and performance. These mounts are designed with a focus on enhancing driving dynamics, utilizing high-durometer rubber for improved durability and performance, without compromising on comfort.

Designed for B5, B6, B7, and C5 Audi models and B5 Volkswagen models, these Density Line Motor Mounts are optimized to be void-free and fluid-free. This eliminates the looseness found in factory mounts, resulting in more precise shifting and superior driving dynamics.

Street Density

The Street Density Motor Mounts are crafted from 50 durometer rubber, making them approximately 10% stiffer than stock mounts. With an optimized, solid-filled design, they achieve a stiffness of around 25% more than stock mounts, reducing drivetrain slop, improving shifting, and minimizing wheel hop – all without a noticeable increase in cabin noise, vibration, or harshness (NVH). Built with steel bases instead of the factory aluminum, these mounts offer enhanced strength for spirited driving.

Track Density

For those looking for maximum performance, the Track Density Mounts are constructed from 80 durometer rubber, making them 90% stiffer than stock. With a solid, void-free design, these mounts are 120% stiffer than stock, delivering a locked-down drivetrain, precise shifting, and virtually no wheel hop. Note that these mounts may cause an increase in NVH in the cabin, which is ideal for track enthusiasts who prioritize performance.

Key Features:

• High-quality 50 Durometer (Street Density) or 80 Durometer (Track Density) rubber with optimized void-free construction
• Reduced drivetrain slop for a more connected driving experience
• Improved engine stability under load
• Direct power transfer and enhanced shifting feel
• Complete drop-in replacement for factory engine mounts
• Sold individually (two mounts required per vehicle)

Fitment:

• Audi A4 (B5) 1996-2001 – 1.8T / 2.8L
• Audi S4/RS4 (B5) 2000-2002 – 2.7T
• Audi A4 (B6) 2002-2005 – 1.8T / 3.0L
• Audi A4 (B7) 2005-2008 – 2.0T FSI / 3.2L FSI
• Note: Tiptronic vehicles with active mounts require two Resistor Bypasses to prevent the MIL light.
• Audi A6 (C5) 1998-2004 – 2.7T / 2.8L / 3.0L
• Audi Allroad (C5) 2001-2003 – 2.7T
• Volkswagen Passat (B5/B5.5) 1998-2005 – 1.8T / 2.8L / 4.0L W8 (Manual transmission only)

Why High-Durometer Rubber?

034 Motorsport uses high-durometer rubber instead of polyurethane for Density Line Mounts because rubber is better suited for managing both tension and compression, providing durability and comfort. Unlike polyurethane, rubber maintains consistent performance without packing or wearing over time, making it ideal for mounts and bushings that experience shear forces.

Street Density vs. Track Density

For daily-driven vehicles, we recommend Street Density Mounts for enhanced performance with minimal NVH. Track Density Mounts are suited for dedicated track cars or drivers who prefer increased engine noise and vibration for a more visceral experience.

Installation Note: These mounts require a torque specification of 25 Nm (approximately 18.5 ft. lbs.) for the nuts. Over-tightening may cause damage to the mounts. Select Street or Track Density from the dropdown menu below. Sold individually – two mounts are required per vehicle.
