Axial Racing SCX10 Steel#45 48 Pitch Spur Gear 85T by GPM SSCX085T  [SSCX085T]

Spur gear for scale drivetrains

This is an RC-scale replacement spur gear intended for Axial Racing SCX10-based rigs and Wraith models. The 85-tooth spur meshes with a matching pinion gear to transfer motor torque into the drivetrain; material and pitch are set to match common 48 pitch systems used on scale crawlers.

Install the spur gear on the transmission or gearbox following your chassis procedure, ensuring correct mesh with the motor pinion. Check backlash and axial alignment, use shims where needed, and avoid excessive preload on bearings. The part is intended as a direct drivetrain component for hobby-grade crawlers and should be handled as a scale model accessory.

For tuning, spur and pinion choices affect acceleration and top-end response; changing tooth counts or adjusting mesh can fine-tune gearing for trail speed versus torque. Regular inspection for wear and proper lubrication at contact surfaces will extend service life in RC conditions.
