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

Durable hardened ring for T-Maxx drivetrains

This hardened steel ring gear is an aftermarket spare for TRAXXAS T-Maxx 1 and T-Maxx 3.3. It acts as the spur that transfers motor torque via the pinion into the gearbox, with direct impact on gear mesh and load sharing across drivetrain components.

Sold as 1 pcs, the hardened ring suits drivers who want a more wear-resistant option compared with softer alloys or nylon spurs. During installation, verify correct mesh and alignment, inspect the mating pinion for wear, and ensure bearings rotate without binding to prevent uneven tooth damage.

Changing to a hardened steel spur does not alter the gear ratio by itself, but can improve long-term wear performance under heavier use; confirm compatibility with your existing spur and pinion before fitting.
