Arrowmax 64P 21T 7075 Hard Pinion Gear - AM-364021

The Arrowmax AM-364021 is a 64 pitch 21 tooth pinion gear machined from 7075 aluminium for use in competitive RC car drivetrains. The 7075 alloy is a high-strength aerospace-grade material, making this pinion gear significantly harder and more wear-resistant than standard 6061 aluminium alternatives. Designed for 1/10 scale touring cars, pan cars, and other RC platforms running 64P gearing, the AM-364021 is a popular choice among racers looking for a precise, durable drivetrain component.

Key Features

• Machined from 7075 hard aluminium for greater hardness and wear resistance compared to standard aluminium pinion gears
• 64 pitch (64P) tooth profile for compatibility with 64P spur gears used in 1/10 scale competition RC cars
• 21 tooth count allows drivetrain tuning for specific motor RPM and track requirements
• Precision-cut teeth help maintain consistent mesh with the spur gear, reducing drivetrain slop
• Lightweight aluminium construction keeps rotating mass low compared to steel pinion gears

Compatible With

• RC cars running 64 pitch (64P) drivetrain gearing
