The lower dogbone mount insert limits compliance of the lower dogbone mount puck by filling large voids in the puck. This upgrade is compatible with our full line of MQB drivetrain upgrades, and offers decreased drivetrain movement, crisper shifting, and reduced wheel hop, with minimal noticeable increase in noise, vibration, or harshness (NVH) inside of the cabin. Rubber does not pack and wear like polyurethane does, which ultimately results in a long-lasting part with consistent performance and comfort.

Lifetime Warranty for Original Purchaser Video Comparison: Lower Insert With and Without Upper Insert During normal and spirited driving, this reduction in compliance results in more direct transitional response of the drivetrain to accelerative and decelerative forces. (Please Note: NVH changes may be more noticeable in vehicles equipped with DSG or Tiptronic transmissions, and/or if your factory engine/transmission mounts are worn or failed. Billet Aluminum Lower Dogbone Mount Insert 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! Rubber is also excellent in shear, where polyurethane is ineffective, making it ideal for control arm bushings that apply a shear force to the bushing during articulation. This testing revealed the cause of the bending, and our engineering team developed the 034Motorsport Billet Upper Dogbone Mount Insert to solve the issue. 5., 0 out of 5 stars Manufacturer HOT BODIES Unlike polyurethane insert options on the market, this billet aluminum part will not pack and wear over time, and guarantees long-lasting performance. 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. 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. 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.
