Precision 55T steel spur for X-Maxx gearboxes

The TXM055TS is a 55-tooth hardened steel spur produced as an aftermarket replacement for TRAXXAS 1/8 X-Maxx gearboxes. Manufactured to tight tolerances, this spur provides a hardened tooth surface aimed at enhanced wear resistance in high-torque brushless applications.

Functionally the component occupies the primary spur position meshing with the pinion; accurate backlash and secure mounting are critical to minimise runout and uneven wear. After installation, rotate the drivetrain by hand to verify smooth engagement and confirm pinion mesh and fastener torque.

Technical notes: switching from plastic to steel increases tooth strength and service life but also raises rotational inertia and may alter NVH characteristics. Reassess pinion selection and ESC thermal margins following material changes to sustain consistent operation under load.

Use the TXM055TS where precision and durability are required for X-Maxx drivetrains, and follow correct mesh and torque procedures during fitting to ensure optimal longevity.

How does hardened steel affect gear runout?

Hardened steel with precise machining helps reduce deformation and uneven wear, but correct mounting and backlash are still required to control runout and ensure consistent meshing.

Are any setup changes needed after swapping to steel?

Expect a slight increase in drivetrain inertia and possible noise; check pinion alignment, consider minor gearing adjustments, and confirm ESC cooling capacity to maintain reliable operation.

What inspection routine do you recommend?

Inspect tooth faces for abnormal wear, verify fastener torque after initial runs, and periodically recheck mesh to ensure the hardened spur is running without binding.

Is this part compatible with standard X-Maxx pinions?

Yes, the TXM055TS is designed to match common X-Maxx pinion profiles for direct replacement, but always confirm final mesh with your chosen pinion before operation.
