TRAXXAS T-Maxx 1 / T-Maxx 3.3 Hard Steel Gear Set for Differential Assembly by GPM STMX1200  [STMX1200]

Hard steel differential gear set for TRAXXAS T-Maxx

This hard steel gear set is an aftermarket differential assembly kit specifically produced for TRAXXAS T-Maxx platforms, supplied by GPM under model STMX1200. The set contains five pcs intended for use inside the RC differential assembly to replace worn internal gears and restore consistent drivetrain engagement. It is described as hard steel to provide increased wear resistance compared with softer stock gears, while remaining an RC-scale accessory only.

Fit and installation considerations focus on careful inspection of mating surfaces and bearings before assembly. Verify clearance and mesh with the spur and pinion, confirm bearings spin freely, and use proper grease or diff oil per your differential type. The parts serve a tuning role by offering a more durable gear surface that can help maintain consistent differential behavior under repeated use, rather than altering gear ratios or vehicle dynamics.

Use this GPM STMX1200 set when replacing internal differential gears on TRAXXAS T-Maxx 1 or T-Maxx 3.3 to restore reliable drivetrain operation; follow standard RC differential service practices during installation.
