The Yokomo PG-6422A is a 22-tooth pinion made from hard coated aluminum to keep rotating mass low while improving surface hardness. It is built to pair with 64 pitch spur gears and works well for both replacement parts and small tuning changes.
Choosing a hard coated aluminium pinion gives you a good mix of durability and low weight, helping to preserve tooth profiles and maintain reliable engagement through long sessions.
Optimised for 64 pitch systems, the Yokomo PG-6422A fits a variety of gearboxes and supports stable power transfer for racers and weekend builders alike.
