034 - Billet Aluminium Dogbone Mount Insert. Volkswagen Golf GTI MK5/MK6/A3/TT/Jetta (2009+) - 034-509-1021

034Motorsport – Billet Aluminium Dogbone Mount Insert
For MK5/MK6 Volkswagen & 8P/8J Audi A3/TT/TTS/TTRS

Upgrade your drivetrain stability with the 034Motorsport Billet Aluminium Dogbone Mount Insert, engineered to reduce wheel hop, tighten drivetrain movement, and improve shift quality — all with minimal additional cabin vibration.

Perfect for tuned vehicles or anyone wanting sharper drivetrain response.
For best results, pair with the 034 Upper Dogbone Insert and 034 Density Line Dogbone Mount Pucks.

The factory dogbone mount contains large voids that allow excess engine and transmission movement, causing sloppy shifting, power loss, and wheel hop. This precision-machined T6-6061 billet aluminium insert fills those voids, providing a tighter, more direct connection to the drivetrain.

Designed using advanced CAD modelling and extensively tested by 034Motorsport and independent enthusiasts, this insert delivers crisp shifts and improved throttle response without introducing unwanted noise or vibration common in cheaper polyurethane designs. It is also more durable, as aluminium will not pack, deform, or wear out over time.

Installation is quick, reversible, and requires no permanent modifications.
