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

Hard steel ring gear for T-Maxx

This hard steel ring gear is an aftermarket replacement designed for TRAXXAS T-Maxx 1 and T-Maxx 3.3. It serves as the spur gear within the RC-scale drivetrain, transferring torque from the motor pinion to the gearbox and affecting gear mesh and load distribution.

Sold as 1 pcs, the ring gear is intended for owners who need a direct replacement or prefer a hardened-steel option for wear resistance compared with softer alloy or nylon alternatives. When fitting, verify correct gear mesh and axial alignment, inspect mating pinion teeth, and ensure bearings rotate freely to avoid premature wear on teeth.

As a tuning consideration, changing to a hardened steel ring gear does not change gear ratios by itself, but it can influence long-term reliability under higher loads; confirm compatibility with your existing spur and pinion dimensions before installation.
