Arrowmax 48P 37T 7075 Hard Pinion Gear - AM-348037

The Arrowmax AM-348037 is a 48 pitch, 37 tooth pinion gear machined from 7075 aluminium for use in 1/10 and 1/12 scale electric RC cars running a 48P drivetrain. Arrowmax produces this pinion gear from 7075-grade hard aluminium, which offers greater hardness and wear resistance than the more common 6061 alloy. The 48P tooth pitch is a widely used standard across touring cars, pan cars, and other on-road and off-road electric RC platforms, making this a practical replacement or gear-ratio tuning option for compatible models.

Key Features

• Machined from 7075 hard aluminium for improved durability and resistance to wear compared to standard alloy pinions

• 37 tooth count allows gear ratio adjustment when used with compatible spur gears
• Precision-machined bore for a secure, accurate fit on standard motor shafts
• Lightweight aluminium construction reduces rotational mass compared to steel alternatives
