This matched set includes a steel #45 89-tooth spur at 48 pitch together with an aluminium adapter, prepared for installation on Axial SCX10 style platforms and Wraith models. The aluminium adapter provides a stable interface between the spur and the vehicle's existing spur housing.
It is intended for scale crawler duty where a durable large-diameter spur is required, or when changing to a higher tooth count for improved low-speed torque under heavy load. Use with a 48 pitch pinion to ensure correct gear mesh in the drivetrain assembly.
Fitment guidance: confirm pinion pitch and clearances before final assembly, set proper running mesh to avoid accelerated wear, and inspect the assembly for runout after tightening the adapter. The adapter centres the spur and helps reduce axial play compared to a direct mount.
A focused upgrade for technicians and serious hobbyists who need a reliable 48 pitch 89T steel spur coupled with an aluminium adapter for secure mounting on SCX10 and Wraith drive systems.
