AXIAL SCX10 II Precision Aluminium Spur Adapter with 57T Hardened Steel Spur SSCX21557T by GPM  [SSCX21557T]

Engineering notes

This precision-machined 6061-T6 aluminium spur adapter is engineered for AXIAL Racing SCX10 II platforms and is paired with a 57T hardened steel spur to improve mesh durability under crawling loads. The aluminium body provides accurate concentricity and low mass, while the steel spur delivers superior wear resistance compared with standard plastic gears.

Fitment requires removal of the factory spur unit, location of the adapter on the gearbox output shaft, and secure fastening of the steel 57T spur using the supplied hardware. Ensure correct axial alignment and verify backlash across the tooth pattern to prevent localized loading.

Suitable for users seeking a robust upgrade, the SSCX21557T allows precise gear stack tuning, consistent mesh repeatability, and easier serviceability in field conditions.

A CNC-friendly upgrade option focused on concentricity and wear performance for SCX10 II drivetrains, combining a 6061-T6 adapter with a hardened 57T steel spur for predictable gear engagement.
