Track focused pinion for consistent gear mesh

The 3RACING 3RAC-PG6430 is a 30 tooth, 64 pitch pinion produced from 7075 aluminium and finished with a hard coating to maintain tooth geometry under repeated load cycles. It is aimed at racers and tuners who require repeatable mesh and minimal dimensional change during competition.

Performance oriented features

  • Material: 7075 aluminium provides high stiffness and minimal mass for efficient rotational inertia.
  • Hard Coating: Surface hardening reduces surface wear and supports consistent contact patch over time.
  • Precision: The 64 pitch 30T configuration is standard for many 1/10 racing drivetrains, enabling fine ratio changes without compromising mesh quality.

What is the best way to verify mesh under race load?

Run the motor briefly while stationary to observe contact pattern on the spur, then adjust to a consistent centre contact with minimal side play for stable performance.

Should I change pinion when changing motor Kv?

Changing Kv may alter rpm and load characteristics; review gear ratio needs first, but the 3RAC-PG6430 remains suitable unless you alter spur tooth count or shaft interface.

Any special break in procedure?

A short run-in at moderate loads helps seat the coating and confirm stable mesh; check tightness of the pinion clamp after initial runs.
