Street Density Line

We're proud to announce the availability of the Street Density Line Transmission Mounts for B5 and C5 Chassis Audi and B5 Chassis Volkswagen models!

034 Motorsport'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 Transmission Mount is manufactured from 50 durometer rubber, which is approximately 20% 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.

Track Density:

The Track Density Transmission Mount is manufactured from 80 durometer rubber, which is approximately 90% 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 a locked-down drivetrain, solid shifting, and virtually no wheel hop. Track Density Mounts will cause a noticeable increase in noise, vibration, and harshness (NVH) inside of the cabin.

Features:

  • Manufactured from 50 Durometer (Street Density) or 80 Durometer (Track Density) Rubber with Void-Free Construction
  • Reduced Drivetrain Slop
  • Decreased Transmission Movement Under Load
  • More Direct Power Transfer
  • Improved Shifting Feel
  • Complete Drop-In Replacement of Factory Transmission Mounts
  • New Installation Hardware Included
  • Sold Individually (One Vehicle Requires 1 or 2 Mounts, Depending on Application)

Fitment:

    • 1.8T / 2.8L - Please Note: Only fits passenger side of manual transmission 1.8T cars. Please visually verify your application before you order.

Warranty:

  • 1 Year Limited Replacement Warranty (If you encounter any issues with our products outside of the warranty period, we will work with you to provide a resolution.)
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.

Street Density vs. Track Density:

We recommend Street Density Mounts for all daily-driven vehicles. They offer a significant increase in performance with a minimal increase in NVH transfer into the cabin. Track Density Mounts are recommended for purpose-built track cars, or those who do not mind significantly increased drivetrain noise and vibration in the cabin.

Please select Street Density or Track Density from the dropdown menu above. 

Sold individually. One vehicle will require 1 or 2 mounts depending on application! 

Note: Only fits passenger side of manual transmission 1.8T cars.  Driver side mount for manual 1.8T cars available here.  Please visually verify your application before you order.

Great for aggressive chewers
Color: Grey
Tuff toy, my yorkie has been trying to tare squeaker out for about 3 days, he works on the fur part but so far it stands up to his chewing, I have gone thru 3 other toys this week so glad thi one works! It lasted 8 days. They need to make whole toy out of material and put fur on top of the tuff material. Once he found out wetting the fur softens it he pulled the seam apart.

Does not stand up to aggressive chewers
Color: Grey
Supposed to be for heavy chewers. My dog destroyed this toy literally in less than 15 minutes. Tore the tail which I sewed back together and then she tore off the nose and pulled out stuffing. Don't know how they tested this. She is only 6 months old and it didn't stand up to her play. Do not recommend if you have an aggressive chewer.

Won't last a day
Color: Blue, Color: Blue
My 50 lb. Pitt bull destroyed this chew toy in 15 minutes. One week later. I'm changing my rating from a one to a five. My girl spent up until now ripping it apart and pulling the stuffing and squeaker out. She had so much fun that I bought her another one. When I took it out of the box for her, she was so happy, she immediately tried to tear it apart.

Lasted 2 minutes
Color: Grey, Color: Grey
Gave it a 2 star bc it was cute and on time. I have a GSD- a mildly aggressive chewer. This toy literally lasted 2 minutes and there was stuffing coming out so I had to take it away. Wish I would have read the reviews before I purchased.

Only Made It Two Weeks
Color: Grey, Color: Grey
This toy easily became my Fig's favorite toy. The squeaker wasn't as annoying as it is in many other dog plushies. However, that's where the positives end. After the first week, there was a hole in the stitching on its neck. I sewed it up, but it obviously did not last. The squeaker went silent after a few more days. I bought it on March 28th, and it is now April 12th. It's just a rag, now. RIP little honey badger. You did well in your short life time.
