Product Description

034Motorsport Billet Aluminium MQB Dogbone Mount Insert Version 2 – VW Mk7 Golf / GTI / R, Audi 8V A3 / S3 / RS3 & Mk3 TT / TTS

Please Note Before Ordering: Your vehicle may have either a Version 1 or Version 2 dogbone mount. You must visually inspect your dogbone before ordering as every vehicle is different. Visually verify your mount using this guide. You can find the Version 1 dogbone mount here.

034Motorsport highly recommend installing this with the MQB Upper Dogbone Mount Insert which prevents the puck assembly from rotating in the subframe housing, which can bend the lower insert and cause premature wearing of the factory rubber in the mount. Click the checkbox to include the MQB Upper Dogbone Mount in your order.

034 Dogbone V1 V2

This precision-machined billet aluminium insert is designed to fill the large voids in the factory dogbone mount, and limit transmission and engine movement without sacrificing ride quality or introducing any perceivable additional noise, vibration, or harshness into the cabin. By filling the void in the factory mount, this insert eliminates the associated slop and ensures that you’re experiencing crisper shifts and a more direct, connected driving experience.

Engineered to work in unison with the factory rubber mount, this insert was designed using CAD software and thoroughly tested and refined to provide noticeable slop reduction without introducing excessive noise or vibration into the cabin, which is common with lesser designs. Unlike polyurethane insert options on the market, this billet aluminium part will not pack and wear over time, and guarantees long-lasting performance.

FEATURES:

  • T6-6061 Billet Aluminum Construction
  • Clear Anodized Finish for Durability
  • Engineered to Fill Void In Factory Transmission Mount
  • Drastically Reduces Transmission Movement During Shifting & Deceleration
  • Improves Shifting Feel, Resulting in Crisper Shifts
  • Virtually No Additional NVH Transfer Inside Cabin
  • Easy, Straightforward Installation Takes Minutes!
  • Lifetime Warranty for Original Purchaser

034Motorsport Billet Aluminium MQB Upper Dogbone Mount Insert

The 034Motorsport MQB Upper Dogbone Mount Insert (patent pending) is required for any MQB platform MkVII VW Golf/GTI/R, MkVII VW GLI, 8V/8V.5 Audi A3/S3/RS3 & MkIII Audi TT/TTS/TTRS using an aftermarket dogbone mount and dogbone mount insert. Aggressive driving that causes violent drivetrain movement, such as burn-outs that induce wheel-hop, will cause the upper and lower dogbone mounts to exert a bending moment on the dogbone mount arm, causing it to bend, and in some cases fail. When this failure occurs, the bottom of the engine is unconstrained and the engine will cause damage to other components in the engine bay. The 034Motorsport MQB Upper Dogbone Mount Insert eliminates these bending forces, allowing the dogbone mount to perform as designed during these violent events.

An aftermarket billet spherical dogbone mount combined with a dogbone mount insert dramatically improves the feel and responsiveness of the drivetrain during spirited driving. However, this combination of modifications, coupled with the design constraints of the MQB dogbone mount pucks have revealed a scenario that applies forces to the dogbone mount arm that it was not designed for.

The lower dogbone mount insert limits compliance of the lower dogbone mount puck by filling large voids in the puck. During normal and spirited driving, this reduction in compliance results in a more direct transitional response of the drivetrain to accelerative and decelerative forces. The driver feels more direct throttle response through the drivetrain without introducing a significant amount of NVH.

However, violent drivetrain shocks, such as burn-out induced wheel-hop, introduce additional forces that can cause damage to the billet spherical dogbone mount arm. In these violent events, the lower puck motion is limited by the dogbone insert, but the upper puck in unconstrained and is free to move forward.

This means that the entire puck assembly rotates forward at an angle towards the front of the car. Because the dogbone mount arm is clamped into the puck assembly, the rotation of the puck assembly generates a bending moment applied to the dogbone mount arm that it was not designed for.

Our testing has shown that regardless of arm design and the material used, the arm cannot be made strong enough to withstand this bending moment. We tested arms manufactured using 6061 aluminium, 7075 aluminium, and stainless steel. The results were all very similar. The dogbone mount arm showed signs of bending with just two burn-out induced wheel-hop events. Complete failure of the dogbone arm occurred in as few as four wheel-hop events. We have high confidence that other brands spherical dogbone mounts will have similar failures.

This testing revealed the cause of the bending, and our engineering team developed the 034Motorsport Billet Upper Dogbone Mount Insert to solve the issue. This insert slips into the front void of the upper dogbone mount puck, limiting the forward motion of the upper puck to match the limited forward motion of the lower puck with the lower insert installed. The result is an upper and lower insert package that eliminates the rotation inside the puck assembly during extreme drivetrain shocks, and keeps the forces acting on the dogbone arm in the direction the arm was designed for. Subsequent testing showed no signs of bending or stress in the dogbone mount arm with both the upper and lower dogbone mount inserts installed. Watch the demonstration video below to see how the dogbone mount pucks move with just the lower insert, and the upper and lower insert combined.

    Great value for money modification to My 2016 JB-1 equipped Skoda Octavia RS wagon. Wheel hop and associated banging noises were tiresome on fast getaways, but this has cured 99% of that! I didn’t notice any extra NVH either, so very happy!

      Thanks for the feedback! Enjoy!

  2. flyingnorseman (verified owner)

    Makes a huge difference to the handling, acceleration is much crisper and car feels “tighter”. Installed in addition with the upper Dogbone mount. Slight vibration present but only on startup. Cheapest and best mod you can do to your MQB based based vehicle!
