Performance-focused spur gear

The 3RACING 64 Pitch Spur Gear 81T, model 3RAC-SG6481, is specified for tuners seeking consistent tooth contact and minimal drivetrain noise under load. Its 64 pitch geometry supports precise pinion matching for predictable lap-to-lap behaviour.

Application and tuning considerations

Designed to integrate with many 1/10 scale drive systems, this 81T spur allows fine adjustments to final drive through incremental pinion changes. Confirm centre distance and gearcase clearance when planning setup changes.

Installation and setup protocol

For best results, set a controlled mesh, secure fastenings to factory torque and perform a short run-in before final checks. Inspect meshing lines and bearing play regularly as part of a race-prep routine.

Verify pitch compatibility, confirm pinion engagement across the full tooth face, and inspect bearings and shafts to ensure no endplay affects mesh under load.
Use incremental pinion changes to tune acceleration versus top speed, logging lap times after each swap to assess impact; small steps prevent unpredictable handling shifts.
Regularly clean gear faces, verify mesh under working conditions and replace bearings or shims that allow side play; consistent setup checks reduce unexpected failures at events.
