3RACING 64 Pitch 63T Racing Pinion 7075 Hard Coated - 3RAC-PG6463  [3RAC-PG6463]

Technical Brief for 3RACING 3RAC-PG6463

The 3RACING 64 Pitch Pinion Gear 63T is precision machined to provide accurate tooth geometry for competitive setups. The 7075 aluminium substrate offers a high strength to weight ratio while the hard coating enhances surface hardness to resist abrasion during high load cycles.

Design and Performance Considerations

Manufactured with tight tolerances, this pinion supports repeatable mesh and consistent torque transfer. The hard coating reduces micro-pitting risk under racing conditions and helps preserve tooth profile when swapping ratios frequently.

Installation and Tuning Notes

For optimal results, confirm 64 pitch matching, verify shaft fit and set screw engagement, and perform a controlled mesh setup using feeler methods. Monitor thermal and wear signs during break-in runs and adjust gearing to maintain desired acceleration and top speed balance.
