The Yokomo PG-6447A pinion is made from hard-coated aluminum to give a durable yet light replacement gear for RC drive systems. Its 64 pitch and 47 tooth count are intended to mesh with spur gears of the same specification for reliable compatibility.
Aluminum pinions reduce rotating mass while maintaining reasonable toughness, which can help sharpen acceleration and throttle response on smooth surfaces. They work well where quick drivetrain reaction is valued.
