TRAXXAS X-MAXX Hardened Steel #45 Front/Rear Wheel Joint by GPM STXM8039/1  [STXM8039/1]

TRAXXAS X-MAXX Hardened Wheel Joint

This 1pc wheel joint is an aftermarket RC-scale replacement part produced for TRAXXAS X-MAXX, intended for use with 8s setups. It is made from hardened steel #45 and designed as a front or rear CVD-style wheel joint to handle higher drivetrain loads common in high-voltage runs.

Design highlights include a CVD body wall thickness of 1.5mm and a shaft pin that is 0.5mm larger than the original joint, while the outer diameter has been increased from 17mm to 18mm to improve power transfer at the wheel. These dimensional changes are focused on mechanical fit and torque delivery rather than electronic or motor changes.

Installation notes: the part installs in the same location as the original wheel joint on TRAXXAS X-MAXX platforms, using existing mounting points and hardware. Inspect mating surfaces and wheel hex fit during installation, and verify clearances with surrounding suspension and body components before running.

Tuning role: this hardened steel joint is intended to provide a stiffer coupling between driveshaft and wheel, which can affect how power is delivered to the ground and how the vehicle responds under heavy throttle. Use it as part of a drivetrain upgrade path when you need consistent mechanical transfer for 8s operation.
