GPM TRAXXAS T-Maxx 1/T-Maxx 3.3 Hardened Steel Ring Gear STMX1201 - RC Spare Part  [STMX1201]

Hardened replacement ring gear for T-Maxx drivetrains

This hardened steel ring gear is an aftermarket replacement made for TRAXXAS T-Maxx 1 and T-Maxx 3.3 vehicles. It functions as the spur within the scale drivetrain, transferring torque from the motor pinion into the gearbox and influencing gear mesh and load sharing across the drive train.

Supplied as 1 pcs, the unit is intended for owners seeking a direct replacement or a higher wear-resistance option compared with softer alloy or nylon spurs. During installation, confirm correct gear mesh and axial alignment, check the condition of the mating pinion teeth, and ensure bearings spin freely to avoid uneven tooth wear.

Note that swapping to a hardened-steel ring gear does not alter gear ratios by itself, but it can increase long-term reliability under heavier loads; always verify spur and pinion tooth counts and mounting pattern before fitting.
