The 3Racing 64 Pitch Spur Gear 83T, part number 3RAC-SG6483, is specified for hobbyists who need repeatable drivetrain geometry and reliable tooth engagement in competitive settings. Its 64 pitch profile and 83 teeth provide a defined step in ratio tuning without introducing excessive axial or radial runout.
Manufactured to standard 64 pitch dimensions, this spur interfaces cleanly with compatible pinions to preserve backlash tolerances. The 83T diameter is suited to many 1/10 scale gearboxes where a higher overall ratio is required for traction management and thermal control of the motor.
When using the 3RAC-SG6483, check pinion alignment, shim motor mounts to maintain consistent mesh, and monitor bearing play to prevent uneven tooth loading. Small pinion increments are recommended to evaluate lap time effects without destabilising handling.
