Arrowmax Pinion Gear 64P 39T 7075 Hard - AM-364039

The Arrowmax AM-364039 is a 64 pitch, 39 tooth pinion gear machined from 7075 aluminium for use in competitive RC car drivetrains. Designed for 1/10 and 1/12 scale electric RC cars that run a 64P gear pitch standard, this pinion gear is a direct-fit option for racers looking for a durable, precisely cut gear in a specific tooth count. The 7075 hard anodised aluminium construction makes it significantly stiffer and more wear-resistant than standard aluminium alloys, which matters when running higher motor speeds or sustained race conditions.

Key Features

• Machined from 7075 aluminium alloy, one of the hardest aluminium grades used in RC racing components
• Hard anodised finish adds a protective surface layer that resists wear and corrosion over extended use
• 64 pitch (64P) tooth profile — ensure your spur gear matches this pitch before ordering
• 39 tooth count allows fine-tuning of your gear ratio for either more top speed or increased acceleration depending on your setup
• Precision CNC machining ensures consistent tooth spacing for smooth, quiet mesh with your spur gear

Compatible With

• RC cars and buggies using a 64P (64 pitch) gear system
• Typically compatible with 1/10 scale and 1/12 scale electric on-road and off-road RC vehicles running standard 64P drivetrains
• Check your motor shaft diameter before fitting — confirm bore size matches your motor
