Upper Dogbone Mount Insert

The 034Motorsport MQB Upper Dogbone Mount Insert is precision-engineered from billet aluminum to protect your drivetrain during extreme driving. When combined with an aftermarket spherical dogbone mount and a lower dogbone mount insert, it dramatically improves drivetrain feel and responsiveness. However, aggressive events like wheel-hop can induce bending moments on the dogbone mount arm, leading to damage or failure. This insert specifically addresses the issue of upper puck rotation during violent drivetrain shocks. By limiting the forward motion of the upper puck, it matches the constrained movement of the lower puck (when used with its corresponding insert). This prevents the puck assembly from rotating, thereby eliminating the damaging bending forces on the dogbone mount arm. Extensive testing with various materials confirmed the arm's susceptibility to this bending moment, with failures occurring in as few as four wheel-hop events. With both the upper and lower 034Motorsport inserts installed, subsequent testing showed no signs of bending or stress on the dogbone mount arm, ensuring it performs as designed under extreme conditions. This product is a crucial addition for enthusiasts who push their vehicles, offering peace of mind and preventing costly repairs.
