TRAXXAS T-Maxx 1/T-Maxx 3.3 Heavy-Duty Ring Gear STMX1201 by GPM  [STMX1201]

Heavy-duty ring gear option for T-Maxx

This hardened steel ring gear is an aftermarket replacement suited to TRAXXAS T-Maxx 1 and T-Maxx 3.3. It serves as the spur gear in the drivetrain, passing torque from the pinion into the gearbox and determining mesh behaviour and load distribution across the gearset.

Provided as 1 pcs, the hardened ring is targeted at users who prefer a tougher alternative to softer alloy or nylon spurs. When installing, verify correct meshing and axial positioning, check pinion tooth condition, and ensure bearings turn freely to prevent early tooth wear.

Replacing with a hardened-steel ring will not change your gear ratio by itself, but it can improve longevity under high-load conditions; always confirm tooth counts and mounting compatibility before fitting.
