This is an RC-scale long axle shaft produced for SMT10-series Axial applications, built from hardened steel #45 for consistent strength in hobby use. The part is described as a long replacement axle intended for platforms including SMT10 and models cited with AX90055 and SWR237L compatibility, and it is positioned to address steering linkage and drivetrain service needs on scale models.
The shaft is presented as a direct-fit replacement for long axle positions on the specified platforms. Installation is standard for axle swaps: remove the hub and bearing carriers, replace the axle with the SMJ237L part, and verify wheel hex and hub clearances before final torque. For tuning, users typically consider axle condition when reducing play in the steering assembly or when refreshing worn drivetrain components.
