Arrowmax 64P 38T 7075 Hard Pinion Gear - AM-364038

The Arrowmax AM-364038 is a 64 pitch 38 tooth pinion gear machined from 7075 aluminium alloy, designed for use in 1/10 and 1/12 scale RC cars running 64P drivetrain configurations. Pinion gears at this pitch and tooth count are a staple in competitive touring car and pan car racing, where precise gear ratio selection directly affects acceleration and top speed. The 7075 alloy used here is significantly harder and more wear-resistant than the 6061 aluminium found in standard pinion gears, making it a sensible choice for racers who want a drivetrain component that holds up under repeated high-RPM use.

Key Features

• Machined from 7075 hard aluminium alloy for improved durability and wear resistance compared to standard 6061 aluminium pinions
• 64 pitch (64P) tooth profile — must be paired with a compatible 64P spur gear for correct mesh
• 38 tooth count allows tuning of gear ratio to favour either acceleration or top speed depending on motor and track conditions
• Precision-cut teeth help maintain consistent mesh and reduce drivetrain noise during high-speed running
• Lightweight aluminium construction keeps rotating mass low, which supports faster motor response

Compatible With

• RC cars and pan cars running a 64P (64 pitch) spur gear
• Typically suits 1/10 scale touring cars and 1/12 scale pan cars with standard 64P drivetrain setups
• Compatible with motors using a 2mm or 3.17mm (1/8 inch) shaft — confirm shaft diameter before ordering as AM-364038 bore size should be verified against your motor spec
