This RC-scale spur is built for Axial Racing SCX10-based rigs and Wraith models using a 48 pitch system. The SSCX085T 85-tooth Steel #45 spur meshes with a matching pinion to translate motor torque into the drivetrain with standard scale pitch compatibility.
Fit the spur to your transmission or gearbox following your chassis routine, ensuring proper mesh with the motor pinion and checking for correct backlash and axial alignment. Use thin shims where necessary and avoid compressing bearings during assembly.
Spur and pinion selections influence acceleration and top-end response, so experiment with different tooth counts to suit trail speed or torque needs. Regular checks for wear and light lubrication at contact points will keep the gear performing reliably.
