Upgrade your Traxxas TRX4 with the GPM TRX4037FX front main shaft, featuring a steel joint and aluminium body to improve torque transfer from the motor to the wheels. This part is aimed at drivers who need stable drivetrain response on uneven surfaces.
The CVD head is shaped to promote seamless rotation, cutting down on wear and improving life span. The crosshead allows a larger articulation angle and is placed toward the front gearbox to maximise driveline function. Positioning the CVD head nearer the middle gearbox reduces friction in tight spaces.
