Axial SMT10 Spur Adapter and 57T Steel Spur MJ1557T by GPM  [MJ1557T]

Precision spur adapter for SMT10 and SCX10 II

This MJ1557T kit includes an aluminium spur gear adapter paired with a 57T steel spur intended for scale RC drivetrains, compatible with the Axial platforms listed. The adapter separates the mounting interface from the spur so the steel 57-tooth gear carries torque while the aluminium adapter keeps the gearbox output aligned.

Made as an aftermarket replacement and upgrade at model scale, the set prioritises mechanical fit and secure fastener retention rather than changing wheel or motor behaviour. When installed correctly the assembly helps keep gear mesh concentric and reduces play between the spur and the transmission interface.

Use this set when you need a direct, model-specific spur gear adapter and a 57T steel spur for Axial SMT10 or SCX10 II variants; always confirm part fit before final installation.
