Race-Oriented 64 Pitch Spur Gear Technical Overview

The 3Racing 64 Pitch Spur Gear 93T Ver.2, model 3RAC-SG6493/V2, is produced with close tolerances to deliver repeatable engagement ideal for time-attack and club racing. The defined tooth profile reduces variable backlash and aids consistent torque transfer across test runs and qualifiers.

Technical Advantages

  • Controlled Tooth Profile: Accurate 64 pitch geometry lowers running lash and yields consistent backlash across the mesh.
  • Durable Material Choice: Selected materials and manufacturing control give resistance to pitting and fatigue under competitive loads.
  • Setup Flexibility: Allows fine tuning of final drive via pinion swaps while maintaining stable engagement characteristics.

What is the recommended pinion adjustment strategy?

Start with a neutral pinion that matches your baseline ratio, then adjust in single-tooth increments while logging lap times and motor temperature to balance speed and efficiency.

How do I validate mesh under race conditions?

Set mesh with a thin feeler, secure fasteners, then run high-load laps and recheck for movement. Consistent contact patch and bearing alignment are key to stability.

Which drivetrain checks pair well with this spur?

Verify pinion runout, inspect motor plate rigidity, and confirm differential preload so the spur gear loads evenly during corner exit and full throttle stretches.

Any break-in recommendations for best longevity?

Run progressive laps at moderate power to seat the gear, then inspect teeth and bearing alignment before full-power qualifying runs to ensure even wear.
