Race Ready 64 Pitch 36T Pinion for Setup Tuning

The 3Racing 64 Pitch Pinion Gear 36T is CNC style machined from 7075 aluminium and finished with a hard coat to improve tooth surface durability. It is intended for racers and tuners who need repeatable gearing behaviour and easy setup changes.

Performance and Tuning Focus

7075 aluminium offers stiffness needed to maintain profile under load while the hard coat helps resist edge wear during aggressive use. This combination supports consistent gear ratios across multiple runs and tuning sessions.

Compatibility with Racing Drivetrains

Specified for 64 pitch systems, the 36T pinion integrates with common racing spurs and allows for precise ratio adjustments. When installing, verify shaft fit and set mesh with a gauge to prevent backlash or binding.

What mesh tolerance should I aim for in a racing setup?

Aim for a minimal but safe clearance that avoids metal contact under load; use a mesh gauge or thin shim method and recheck after a brief run.

Can this pinion handle repeated high RPM sessions?

The hard coated 7075 construction improves wear resistance for repeated sessions, but monitor for coating wear and replace if tooth integrity falls below race requirements.

Any recommendations for pairing with spurs for competitive use?

Use a high quality 64 pitch spur with matching tooth profile, ensure concentric mounting and secure pinion fastening to prevent slippage under race loads.
