Race-Focused 64 Pitch Pinion for Accurate Gear Mesh

The 3RACING 3RAC-PG6437 64 Pitch Pinion Gear 37T is produced from 7075 aluminium with a hard coat to extend service life under competitive conditions. The 64 pitch profile provides tighter tooth engagement for predictable power transfer and reduced slop during high rpm runs.

Tuning Considerations for Competitive Use

When setting up this pinion, aim for a minimal, even mesh to preserve tooth geometry and limit premature wear. The robust 7075 substrate and surface treatment help maintain consistent contact pattern across repeated runs, which supports repeatable lap times.

Compatibility and Setup Tips

Intended for 1/10 scale electric vehicles using 64 pitch spurs, the 37T option is useful when adjusting overall gear ratio for track-specific requirements. Verify pinion seating and locking screw torque, and inspect mesh after initial break-in runs.

Set a small, even clearance using shim material or the paper method. Rotate the drivetrain slowly to confirm full tooth contact without binding before securing the pinion.
The surface treatment reduces abrasive wear on the tooth flanks, helping preserve gear geometry under the higher loads common in racing applications.
Run a few low-load sessions to allow surfaces to settle, then recheck mesh and fasteners. This helps achieve a stable contact pattern for consistent lap performance.
