Race-oriented 64 pitch spur by 3Racing

The 3Racing 64 Pitch Spur Gear 104T Ver.2, referenced 3RAC-SG64104/V2, is specified for drivers requiring fine-grain ratio control and repeatable drivetrain response. The 104 tooth profile provides closer step changes, useful for dialling setups in competitive environments.

Performance and tuning focus

This spur delivers predictable engagement that helps maintain consistent mesh under load, enabling more reliable lap-to-lap performance. Its tooth count supports incremental pinion adjustments for precise top speed and acceleration trade-offs.

Race setup guidance

When integrating the 3RAC-SG64104/V2, verify pinion alignment and backlash with the intended motor and gearing. Use light running-in procedures to ensure stable contact patterns, then lock down mesh settings for race conditions.

How does the 104T help in tuning for circuits?

The higher tooth count allows for smaller pinion steps, making it easier to find the optimal balance between acceleration out of corners and top speed on straights.

Any setup tips to prevent overheating?

Ensure correct mesh and smooth tooth contact to minimise friction. Monitor drivetrain temperatures during practice runs and adjust gearing if excessive heat appears.

What should I check after a crash?

Inspect the spur for chipped teeth and confirm the pinion and shaft run true. Re-establish mesh and check for any loosened fasteners before returning to competition.

Is this spur suited for quick gear ratio changes at events?

Yes, the 104T permits finer ratio tuning, which is helpful for adapting to track conditions between heats without large jumps in behaviour.
