TRAXXAS T-Maxx 1/T-Maxx 3.3 Hardened Steel Ring Gear STMX1201 by GPM  [STMX1201]

Precision hardened ring gear for high-load T-Maxx use

This hardened steel ring gear is offered as an aftermarket spare for TRAXXAS T-Maxx 1 and T-Maxx 3.3. As the primary spur, it transfers motor torque from the pinion into the gearbox and plays a key role in mesh accuracy and load distribution across the drivetrain.

Supplied as 1 pcs, the component is designed for hobbyists seeking a more wear-resistant alternative to softer spurs. For best results during fitment, verify tooth counts and mounting pattern, establish correct mesh with measured clearance, inspect mating pinion teeth condition, and confirm bearings rotate freely to avoid uneven stress on gear teeth.

Note that adopting a hardened-steel ring gear does not change the gear ratio by itself but can enhance durability under sustained torque. Confirm dimensional compatibility with your existing spur and pinion before installation.
