Precision hard-steel differential gears for TRAXXAS T-Maxx

Model STMX1200 is a 5-piece hard steel internal gear set developed as an aftermarket upgrade for TRAXXAS T-Maxx differentials. The set replaces worn internal gears with a harder steel surface to improve wear resistance and maintain consistent drivetrain engagement over extended running.

Installation best practice: inspect and, where necessary, renew bearings and mating components, verify correct gear mesh and backlash relative to spur and pinion, and apply appropriate grease or diff oil for the differential type. Perform a controlled run-in to allow the new steel teeth to seat evenly. This set is intended to enhance internal durability while preserving original gear ratios.

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

Use STMX1200 when replacing internal differential gears on TRAXXAS T-Maxx 1 or T-Maxx 3.3 to restore reliable drivetrain performance; follow standard RC differential servicing procedures during fitment.

What material processes improve STMX1200 durability?

The gears use a hard steel specification to increase surface wear resistance compared with softer stock components. Proper mesh and lubrication are still critical to maximize service life.

Are dimensional checks required before assembly?

Yes. Verify tooth engagement, lateral play and bearing seating. Confirm the STMX1200 gear set matches your diff internal geometry before final assembly.

Which lubricants suit hardened internal gears?

Use diff oils or greases recommended for your differential design; medium viscosity diff oils and quality gear greases balance wear protection with acceptable noise levels.

Will STMX1200 affect driveline tolerances?

When installed with correct mesh and undamaged mating parts, the set preserves original driveline tolerances. Incorrect mesh or worn bearings can introduce additional stresses.
