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

Hardened wheel joint for X‑MAXX

This 2 pcs set is an aftermarket wheel joint designed for TRAXXAS X-MAXX platforms running 6s power. The component is a direct replacement-style RC accessory intended to improve driveline robustness and to provide a firmer interface between the axle and wheel under high-load conditions.

Key mechanical changes compared with the original joint are provided in the product design: the CVD body thickness is specified at 1.5mm, the shaft pin is produced 0.5mm thicker than stock, and the outer diameter is increased from 17mm to 18mm to help increase rear power transfer. These dimensional updates target driveline stiffness and contact area without altering basic fitment geometry.

Installation typically follows standard wheel-joint replacement procedures on X-MAXX scale models, and the part serves as a tuning option for drivers seeking firmer power delivery to the wheels. Evaluate drivetrain alignment and clearances after fitting, and inspect for proper engagement with the hub and axle under static load before final use.

As a scale RC spare, this GPM STXM039 wheel joint is intended for hobbyists who want a stiffer driveline response on TRAXXAS X-MAXX models using 6s power; it provides dimensional upgrades aimed at improving rear power transfer while retaining stock-style fitment.
