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

Aftermarket wheel joint for TRAXXAS X-MAXX

This single-piece wheel joint is an aftermarket replacement made for TRAXXAS X-MAXX and intended for 8s setups. It is manufactured from hardened steel #45 and configured as a front or rear CVD-style joint to withstand elevated drivetrain loads seen in high-voltage running.

Key dimensions include a CVD body wall thickness of 1.5mm, a shaft pin 0.5mm larger than the original part, and an increased outer diameter from 17mm to 18mm to improve power transfer at the wheel. These dimensional updates focus on mechanical fit and torque delivery rather than changes to electronics or motor hardware.

Installation notes: this part fits the same location as the original wheel joint on TRAXXAS X-MAXX chassis, using existing mounting points and standard hardware. Inspect mating surfaces and wheel hex engagement during fitting, and confirm clearances with surrounding suspension and bodywork before first use.

Tuning role: the hardened steel joint is designed to produce a firmer coupling between driveshaft and wheel, which can alter traction feel and throttle response under heavy power. Fit it as part of a drivetrain upgrade path when you require consistent mechanical power transfer for 8s operation.
