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

Hardened 55T spur for X-Maxx drivetrains

The TXM055TS is a 55-tooth steel spur created as a direct-fit aftermarket replacement for TRAXXAS 1/8 X-Maxx gearboxes. It gives a hardened tooth surface that resists chipping and wear in high-torque brushless setups where stock plastics or softer alloys show fatigue.

This component sits as the main spur mesh with the pinion inside the gearbox, so setting correct backlash and tightening the mount bolts to spec are key. After fitting, hand-rotate the drivetrain to check for smooth engagement and confirm the pinion-to-spur mesh before applying power.

Tuning considerations: steel spurs add a small amount of rotational inertia and can be noisier than plastic, but they significantly reduce risk of tooth failure under heavy load. Re-evaluate pinion tooth count and monitor ESC and motor temperatures after switching materials to keep the system reliable.

Choose this 55T steel spur when you need a durable, like-for-like replacement for X-Maxx drivetrains and always double-check gear mesh and mounting torque during installation to avoid premature wear.
