Arrowmax 48P 22T 7075 Hard Pinion Gear - AM-348022

The Arrowmax AM-348022 is a 48 pitch 22-tooth pinion gear machined from 7075 aluminium for use in 1/10 and similarly scaled RC cars running 48P drivetrain setups. Arrowmax produces this pinion from 7075-grade hard aluminium alloy, which is significantly harder and more wear-resistant than the softer 6061 alloy commonly used in budget pinion gears. The AM-348022 is designed to mesh with 48P spur gears and suits a wide range of electric RC cars that use this standard pitch.

Key Features

• Machined from 7075 hard aluminium alloy for greater durability and wear resistance compared to standard 6061 aluminium pinions
• 48 pitch (48P) tooth profile meshes correctly with 48P spur gears — not compatible with 32P or 64P setups
• 22-tooth specification affects final drive ratio and motor output speed, useful when tuning gearing for different track conditions or motor KV ratings
• Anodised finish helps protect the alloy surface and aids identification

Compatible With

• RC cars and buggies running 48 pitch (48P) spur gears
• Motors with a standard pinion shaft diameter compatible with Arrowmax 48P pinion bores
• Commonly used in 1/10 scale electric on-road and off-road RC platforms specifying 48P gearing
