TRAXXAS X-MAXX CVD-Style Hardened #45 Wheel Joint STXM8039/1 by GPM  [STXM8039/1]

Upgraded wheel joint for TRAXXAS X-MAXX use

This 1pc wheel joint is an aftermarket replacement produced for TRAXXAS X-MAXX and specified for high-voltage 8s running. Constructed from hardened steel #45, it operates as a front or rear CVD-style joint suited to heavier drivetrain loads.

Design notes: the CVD body wall is 1.5mm thick, the shaft pin is increased by 0.5mm over the original, and the outer diameter has been raised to 18mm from 17mm to improve mechanical power transfer at the wheel. These changes target fit and torque handling rather than any electronic modifications.

Fitment guidance: installs in the factory location on TRAXXAS X-MAXX platforms using existing mounting points and hardware. During installation inspect hex fit and mating faces, and confirm there is adequate clearance with suspension and body components.

Tuning perspective: this hardened joint stiffens the driveshaft-to-wheel connection and can change throttle delivery characteristics under heavy load. It is a practical upgrade for builders seeking reliable mechanical transfer on 8s setups.
