TRAXXAS T-Maxx Differential Hard Steel Gear Set STMX1200 by GPM  [STMX1200]

Aftermarket hard-steel gears for TRAXXAS T-Maxx differentials

This 5-piece hard steel gear set is an aftermarket replacement designed for TRAXXAS T-Maxx platforms and references model STMX1200. The kit replaces worn internal differential gears to recover smooth engagement and improved wear life compared with softer stock parts.

Before fitting, inspect bearing condition and mating surfaces, check gear mesh and clearance with the spur and pinion, and confirm bearings rotate freely. Use the correct grease or diff oil for your differential type and run the new gears in gently to seat the teeth. These gears are intended to increase internal gear durability without changing gear ratios or fundamental vehicle handling.

Select the STMX1200 hard steel set when servicing internal differential gears on TRAXXAS T-Maxx 1 or T-Maxx 3.3 and follow standard RC differential service procedures for best results.
