This is a replacement spur gear and aluminium adapter sold as a single set, designed for Axial SCX10 platforms and Wraith models. The kit combines a steel #45 89-tooth spur at 48 pitch with an aluminium spur adapter to mount cleanly to the vehicle's existing spur housing.
Use this set when you want a more wear-resistant large spur for trail and crawler duty, or when swapping to a heavier gear ratio for low-speed torque under load. It is intended for model-scale drivetrain use and requires a matching 48 pitch pinion from your motor to establish correct mesh.
Installation notes: verify pinion compatibility and clearances before final assembly, set proper gear mesh to avoid premature wear, and check for runout after the adapter is tightened. The adapter aligns the spur to the gearbox interface and helps reduce axial play compared with a direct-mount arrangement.
The set suits hobbyists tuning scale crawlers who need a robust, 48 pitch 89T spur with an aluminium adapter for reliable mounting on SCX10 and Wraith platforms.
