5-piece hard steel differential internals for TRAXXAS T-Maxx

Model STMX1200 is a five-piece hard steel gear set supplied as an aftermarket replacement for TRAXXAS T-Maxx differentials. The harder material helps resist wear inside the diff, making it a practical choice for frequent running where stock gears show premature wear.

Careful installation is important: check bearing condition, confirm proper gear mesh and backlash with the spur and pinion, and choose the correct grease or diff oil for your setup. The set is designed to preserve original drivetrain ratios while delivering improved internal durability.

Is STMX1200 suitable for racing use?

These hard steel internals are built for increased wear resistance, which can be beneficial for high-use or competitive environments, but ensure compatibility with your diff type first.

Do I need special tools to fit the gears?

Standard RC toolbox items such as hex drivers, diff grease, and a gear mesh tool are sufficient. Replace any damaged bearings during the service.

Can I mix these with stock gears?

Mixing materials is possible but not recommended; fit a full matching set to ensure even wear and consistent mesh across the differential.

What should I inspect after installation?

After installation, check for smooth rotation, correct backlash, and listen for unusual noises at low speed. Re-torque fasteners after initial run-in if needed.
