3Racing 3RAC-PG6422 Pinion for Competitive Tuning

Engineered for track use, the 3Racing 64 Pitch Pinion Gear 22T employs 7075 aluminium and a hard-coated finish to preserve tooth geometry under repeated runs. The fine 64 pitch allows for narrow mesh tolerances, which aids predictable drivetrain response during setup changes.

Technical Highlights

  • 7075 Aluminium: Provides a high strength to weight ratio to keep rotating inertia low while resisting deformation.
  • Hard Coating: Surface treatment reduces abrasive wear and helps maintain consistent contact patterns across sessions.
  • 64 Pitch Compatibility: Fine pitch supports tight, repeatable gear engagement essential for competitive tuning.

Application and Tuning Notes

This 22T pinion is intended for racers prioritising repeatable mesh and quick gearing swaps. Confirm pinion seating and set minimal safe clearance to avoid premature wear or binding.

What mesh clearance should I aim for?

Aim for a minimal clearance that prevents binding while avoiding excess backlash; small adjustments yield noticeable changes in drivetrain feel.

Will the hard coating affect gear profiling work?

The coating preserves surface condition during profiling and repeated use, but accurate initial machining and mesh setup remain critical for optimal contact patterns.

Is this pinion suitable for frequent gearing changes?

Yes, the 7075 material and hard finish make it durable for multiple installs, though inspect set screws and tooth faces after each swap.
