Replacement hard steel internals for TRAXXAS T-Maxx differentials

The STMX1200 hard steel gear set is an aftermarket 5-piece kit intended for TRAXXAS T-Maxx differentials. It replaces worn internal gears with harder steel parts to extend service intervals and maintain more consistent drivetrain engagement under repeated use.

Installation notes: inspect bearings and gear seats, confirm correct mesh against spur and pinion and select the proper diff oil or grease for your differential style. These gears do not change ratios but provide a tougher internal surface to resist wear from heavy use.

Specifications

  • Item: Hard Steel Gear set for Differential Assembly - 5pcs
  • Material: Hard steel
  • Model Number: STMX1200
  • Compatibility: TRAXXAS T-Maxx 1 / T-Maxx 3.3

Fit the STMX1200 set when renewing internal differential gears on TRAXXAS T-Maxx 1 or T-Maxx 3.3 and follow routine RC diff maintenance for reliable results.

Will these gears fit my T-Maxx differential housing?

They are listed as compatible with TRAXXAS T-Maxx 1 and T-Maxx 3.3; match the internal layout and part count to confirm fit before ordering.

Can hard steel cause extra wear elsewhere?

Harder gears can increase load on mating parts if mesh is incorrect. Proper setup and lubrication prevent premature wear on bearings and pinion gears.

Is a full differential rebuild recommended?

If bearings or housings show wear, replace those parts during the rebuild. This kit covers only the internal gears themselves.

How do I set the correct backlash?

Adjust gear mesh so there is minimal play without binding. Use feel and a thin shim or the standard mesh method, then secure and test at low speed.
