GPM Racing Hardened Steel #45 Motor Gear 17T for Traxxas 1/10 MAXX (TXMS017TS)

17T Hardened Steel Pinion for MAXX Motor Interface

This 17T motor pinion is an engineered replacement that couples directly with the motor input on the TRAXXAS MAXX platform. Supplied in hardened steel #45, the profile is designed to deliver improved wear resistance and consistent tooth engagement to support stable drivetrain performance under normal running and tuning conditions.

Fitting recommendations: verify correct mesh against the spur gear and ensure the pinion is fully seated on the motor shaft before tightening. The supplied contents list the motor pinion and a 4x4 set screw for retention. Use this item for routine service replacement or when refreshing the drivetrain after wear has been observed.

What material specification is used?

The pinion is made from hardened steel #45, chosen to resist wear while maintaining reliable tooth engagement during typical RC drivetrain loads.

How should I verify fitment?

Confirm motor shaft dimensions and spline compatibility with the TRAXXAS MAXX pinion interface, then check mesh with the spur gear and secure using the provided 4x4 set screw.

When is replacement recommended?

Replace the pinion if tooth wear, chipping or inconsistent engagement is found; renewing the pinion helps restore consistent drivetrain contact and reduces wear on the spur. Write Product Review Please sign in your account before you can write any review. Sign In Close
