Performance Tuning with the 3Racing 69T Spur

The 3Racing 48 Pitch Spur Gear 69T Ver.2 is engineered for competitive setups where repeatable gearing changes matter. Its 69 tooth geometry offers fine ratio steps so racers can tune acceleration and top speed without major drivetrain alterations.

Racing-Oriented Details

  • Consistent Tooth Geometry: Produces reliable mesh for predictable power transfer during aggressive runs.
  • Pinion Compatibility: Matches standard 48 pitch pinions used in many racing platforms for straightforward swaps.
  • 69T Adjustment Range: Enables incremental final drive changes to refine lap time without drastic hardware changes.

How do I choose the right pinion with this 69T spur?

Select a 48 pitch pinion that yields your target final ratio and keeps motor RPMs in the efficient range; small pinion changes give predictable steps with the 69T spur.

What checks should I perform before racing?

Confirm precise mesh under static and dynamic conditions, ensure secure fastenings, and run a brief break-in period while monitoring temperature and wear.
