Arrowmax 48P 40T Pinion Gear 7075 Hard - AM-348040

The Arrowmax AM-348040 is a 48 pitch, 40 tooth pinion gear machined from 7075 hard aluminium, designed for use in 1/10 and 1/12 scale electric RC cars running 48P drivetrain setups. Arrowmax produces this pinion gear from 7075-grade aluminium alloy, which is significantly harder and more wear-resistant than the more common 6061 alloy, making it a solid choice for racers and hobbyists who put their drivetrain under consistent load. The AM-348040 part number makes it easy to cross-reference when ordering replacements or building out a set of pinion gears across different tooth counts.

Key Features

• Machined from 7075 hard aluminium for greater durability and wear resistance compared to standard 6061 alloy pinions
• 48 pitch (48P) tooth profile matches standard 48P spur gears used across a wide range of competitive and club-level electric RC cars
• 40 tooth count suits setups where lower motor speeds or increased torque is preferred over top-end punch
• Precision CNC machining ensures accurate tooth geometry for smooth, consistent mesh with compatible 48P spur gears
• Lightweight aluminium construction reduces rotating mass compared to steel pinions

Compatible With

• RC cars and buggies running a 48 pitch (48P) gear system
• Typically suits 1/10 scale electric touring cars, buggies, and stadium trucks
• Also compatible with many 1/12 scale electric RC cars using 48P drivetrains
• Compatibility depends on motor shaft diameter — verify shaft size before ordering
