GPM TRAXXAS X-MAXX Harden Steel #45 Wheel Joints STXM039 - RC Spare Part  [STXM039]

Reinforced wheel joint for X-MAXX

This 2 pcs set is an aftermarket wheel joint made for TRAXXAS X-MAXX platforms running 6s power. The component is a direct replacement-style RC part aimed at increasing driveline robustness and providing a firmer interface between axle and wheel under high load conditions.

Key mechanical updates versus the original joint are built into the design: the CVD body is 1.5mm thick, the shaft pin is 0.5mm larger than stock, and the outer diameter grows from 17mm to 18mm to help improve rear power transfer. These dimensional changes focus on driveline stiffness and contact area while preserving basic fitment geometry.

Installation follows standard wheel-joint replacement steps on X-MAXX scale models, and the item is a tuning option for drivers who want firmer power delivery to the wheels. After fitting, check drivetrain alignment and clearances, and verify hub and axle engagement under static load before normal use.

As a scale RC spare, this STXM039 wheel joint suits hobbyists who want a stiffer driveline response on TRAXXAS X-MAXX models running 6s power; it delivers dimensional upgrades intended to improve rear power transfer while keeping stock-style fitment.
