This replacement kit contains a steel #45 89T spur at 48 pitch together with an aluminium adapter, intended for Axial SCX10 and Wraith scale crawlers. The two-piece set mounts to the vehicle's existing spur housing using the adapter for a clean fit.
Use the kit to increase durability for trail work or when fitting a larger spur for better low-end torque under load. It is designed for model-scale drivetrain use and requires a matching 48 pitch pinion to get the correct mesh and reliable operation.
Fitting pointers: confirm your pinion is 48 pitch and allow correct clearance before final tightening, establish proper gear mesh to prevent early tooth wear, and inspect for any wobble after installation. The adapter centres the spur on the gearbox and helps limit axial movement.
A straightforward upgrade for owners wanting a robust 48 pitch 89T steel spur with an aluminium adapter to improve mounting and durability on SCX10 and Wraith drivetrains.
