034Motorsport Track Density Strut Mount for Audi A3, TT and VW Golf, GTI, Jetta, Passat, Tiguan, and More (2005–2019)

Built as a complete drop-in replacement for the factory strut mount, the 034Motorsport 034-601-1004-TD Track Density strut mount fits the Audi A3 and TT and the Volkswagen Beetle, CC, Eos, Golf, GTI, Jetta, Passat, R32, Rabbit, and Tiguan. It uses 75 durometer rubber, which 034Motorsport rates at about 50% stiffer than stock. The rubber is fully vulcanized to the center cups to extend the mount's service life. 034Motorsport also redesigned the steel mount body to handle the added stress of spirited driving. Each mount is made in the United States.

034Motorsport parts sold by PMB carry a 24-month warranty.

This is a fully re-engineered mount, so you replace the whole factory mount rather than adding inserts to it. It reduces deflection at the top of the strut and holds suspension geometry under load, which sharpens steering feel. On cars running coilovers, it also stops the squeak that factory mounts often make. 034Motorsport says the cabin sees only a minimal increase in noise, vibration, and harshness. The mount supersedes the factory parts 1K0412331B, 1K0412331C, and 8J0412331. It is priced individually, and one vehicle needs two.

Installation & Tuning Notes

The mount installs in the factory location with no modification. Strut mounts wear with mileage as the bearing degrades and the rubber cracks, so replace them whenever you fit new strut assemblies. With coilovers, the vulcanized design addresses the squeak that stock mounts produce.

Common Questions

Will this mount make the car noticeably louder inside?
034Motorsport says the Track Density mount causes only a minimal increase in cabin noise, vibration, and harshness.

What are the signs of a failing strut mount?
Look for clunking over bumps, vibration through the steering wheel or chassis, poor steering response, uneven tire wear, and more body roll in corners.

PMB sells this mount for owners who want a firmer strut top without a harsh cabin.
