TRAXXAS 1/8 X-Maxx 55T Steel Spur Gear by GPM TXM055TS  [TXM055TS]

55T steel spur gear for X-Maxx

The GPM TXM055TS is a 55-tooth steel spur gear produced as an aftermarket replacement for TRAXXAS 1/8 X-Maxx platforms. Designed as a direct-fit large-diameter spur, it addresses common wear points in high-torque, 6S-capable setups by supplying a hardened steel surface where stock plastic or softer alloys may degrade under load.

Functionally this part sits in the gearbox as the primary spur mesh with the pinion gear, so correct backlash and secure mounting are essential. When replacing the spur gear, confirm the pinion mesh, re-torque mounting hardware, and rotate the drivetrain by hand to verify smooth engagement before running the model.

Tuning notes: switching to a steel spur can slightly increase drivetrain inertia and noise compared with plastic, but it improves resistance to tooth chipping under aggressive throttle and heavy brushless motor torque. Consider reviewing motor pinion tooth count and ESC thermal management after changing materials to maintain reliable operation.

Use this steel 55T spur when you need a durable replacement that maintains original fitment for the X-Maxx drivetrain, and always verify gear mesh and mounting torque during installation to prevent premature wear.
