Arrowmax 64P 42T 7075 Hard RC Pinion Gear - AM-364042

The Arrowmax AM-364042 is a 64 pitch 42-tooth pinion gear machined from 7075 aluminium for use in competitive RC cars running 64P drivetrain setups. Arrowmax produces this pinion gear for racers who need a precise, hard-wearing gear that holds its mesh under sustained power. The 7075 aluminium alloy is significantly harder than the more common 6061 grade, making it a suitable choice for high-RPM electric motors where gear wear is a real concern.

Key Features

• 64 pitch (64P) tooth profile matches standard 64P spur gears used across a wide range of 1/10 scale touring car and pan car platforms
• 42-tooth count suits mid-to-high speed gearing ratios depending on your spur gear selection and motor KV rating
• Machined from 7075 hard aluminium alloy for greater hardness and wear resistance compared to standard 6061 aluminium pinions
• Precision CNC machining ensures consistent tooth geometry and accurate mesh for reduced drivetrain noise and vibration
• Lightweight aluminium construction keeps rotating mass low, which is particularly relevant in competitive racing applications

Compatible With

• RC cars and touring car platforms using 64P (64 pitch) gear systems
• 1/10 scale electric on-road and touring car drivetrains
• Motors with a 3.175mm (1/8 inch) shaft — verify your motor shaft diameter before fitting
