Precision-fit hard steel gears for T-Maxx differentials

The STMX1202 is an aftermarket hard steel gear set compatible with TRAXXAS T-Maxx 1 and T-Maxx 3.3 differential assemblies. Supplied as a 6 pcs set, it contains the internal gear train components plus shims and O-rings to assist correct load-bearing mesh and internal sealing. The design intent is to provide a durable replacement option for worn internal gears while maintaining original differential geometry.

As an aftermarket component for TRAXXAS T-Maxx platforms, these parts are intended for hobby use. During rebuilds, confirm gear mesh, verify shim stack thickness, and ensure bearing seats and case alignment are within tolerance. The included O-rings provide internal sealing where required and the shim options allow precise backlash adjustment to maintain consistent engagement under operational load.

What verification steps should I perform before final assembly?

Verify gear runout, confirm bearing seating, and set initial shim stacks to achieve minimal backlash with smooth rotation. Recheck after a short break-in run and retorque fasteners.

Are any additional parts required for fitment?

The kit includes the internal gear pieces, shims and O-rings needed for a standard rebuild. Inspect your housing and bearings; replace worn bearings or seals as necessary for a complete service.

How should I inspect mesh after installation?

Rotate the assembly under light load, observe mesh contact pattern, and adjust shims to eliminate excessive play while avoiding tight binding. Confirm free bearing rotation under load.

What maintenance do steel gears need versus plastic?

Steel gears typically require inspection for wear and proper lubrication rather than replacement for minor damage. Check bearings and seals regularly to prevent premature wear on mating surfaces.
