3Racing 3RAC-PG6438 Race Grade 64 Pitch 38T Pinion - Hard Coated  [3RAC-PG6438]

Race focused 64 pitch pinion for tuneable performance

The 3Racing 64 Pitch Pinion Gear 38T, model 3RAC-PG6438, is produced for competitive tuners who require consistent ratio stepping and durable tooth geometry. Machined from 7075 aluminium and hard coated, it supports repeatable mesh settings and resists profile wear under race conditions.

Engineered for consistent drivetrain behaviour

7075 aluminium provides material stiffness while keeping mass low to reduce rotational inertia. The hard coat reduces micro abrasion so tooth geometry remains consistent lap after lap, aiding predictable power transfer.

Small ratio increments for setup tuning

The 64 pitch format enables finer adjustments to top speed versus acceleration, which helps when optimising setups for specific tracks or surface conditions. This pinion is intended as a tuning component for racers seeking repeatable results.
