The GPM TRX4037FX front main shaft replaces the stock shaft with a steel joint and aluminium body to provide a robust interface between motor output and the front driveline on the Traxxas TRX4. The part is engineered to maintain consistent torque transfer during extended trail use.
The CVD head design supports smooth, continuous rotation to limit wear on moving surfaces. The crosshead enables a greater rotation angle and is positioned toward the front gearbox to optimise driveline geometry. Locating the CVD head closer to the middle gearbox reduces friction where packaging is constrained.
