GPM TRAXXAS X-MAXX Harden Steel #45 Wheel Joints STXM039 - Chassis Option  [STXM039]

Reinforced axle-to-wheel joint for X-MAXX

This 2 pcs set is an aftermarket wheel joint built for TRAXXAS X-MAXX vehicles running 6s power. It is a replacement-style RC component intended to boost driveline strength and create a firmer connection between the axle and wheel under heavy loads.

Design differences from the stock joint are explicit: the CVD body thickness is 1.5mm, the shaft pin diameter is 0.5mm larger than stock, and the outer diameter increases from 17mm to 18mm to assist rear power transfer. Those dimensional tweaks aim to increase stiffness and contact area while keeping fitment geometry intact.

Fitment follows normal wheel-joint replacement procedures for X-MAXX scale models. Treat this as a tuning upgrade for firmer power delivery and validate alignment and clearance after installation, inspecting hub engagement before running.

As a scale replacement part, STXM039 targets hobbyists seeking firmer driveline feel on TRAXXAS X-MAXX platforms using 6s batteries; it focuses on dimensional improvements to aid rear power transfer while retaining stock-style fit.
