TRAXXAS X-MAXX Heavy-Duty #45 Wheel Joint STXM8039/1 by GPM  [STXM8039/1]

Heavy-duty wheel joint for TRAXXAS X-MAXX

This single-piece aftermarket wheel joint is made for TRAXXAS X-MAXX and intended for 8s power systems. Made from hardened steel #45, it serves as a front or rear CVD-style joint to cope with increased drivetrain forces.

Specification highlights include a 1.5mm CVD body wall, a shaft pin sized 0.5mm larger than the OEM joint, and an outer diameter increase to 18mm to aid power transfer at the wheel. The modifications are focused on mechanical strength and torque delivery rather than electrical or motor changes.

Installation advice: the part mounts in the original joint location on TRAXXAS X-MAXX chassis and uses the same mounting points and hardware. Always check mating surfaces, wheel hex engagement, and clearance with nearby suspension or body parts before running.

Performance note: fitting this hardened steel joint will stiffen the connection between driveshaft and wheel and can alter how power is applied under heavy throttle. Use it as part of a drivetrain upgrade for consistent mechanical transfer during high-voltage operation.
