Arrowmax 48P 45T 7075 Hard Pinion Gear - AM-348045

The Arrowmax AM-348045 is a 48 pitch 45-tooth pinion gear machined from 7075 aluminium for use in 1/10 and 1/12 scale RC cars running a 48P drivetrain. Arrowmax produces this gear from 7075-grade hard aluminium, which is significantly stiffer and more wear-resistant than the standard 6061 alloy used in many entry-level pinion gears. If your current pinion is showing signs of wear or you need a specific tooth count to tune your gear ratio, the AM-348045 is a direct-spec replacement or ratio-tuning option for compatible 48P setups.

Key Features

• 48 pitch (48P) tooth profile — matches the most common gearing standard used in 1/10 and 1/12 scale RC cars
• 45 tooth count allows fine-tuning of your final drive ratio for more top speed or torque depending on your spur gear pairing
• Machined from 7075 hard aluminium for increased durability and resistance to wear compared to softer alloy alternatives
• Arrowmax precision machining ensures accurate tooth profile and consistent mesh with 48P spur gears
• Lightweight metal construction reduces rotational mass in the drivetrain

Compatible With

• RC cars and buggies using 48 pitch (48P) gearing systems
• 1/10 scale on-road and off-road RC vehicles with 48P drivetrains
• 1/12 scale RC cars with 48P spur and pinion setups
• Compatible motor shaft diameter must be confirmed before fitting — check your motor's shaft size against the gear's bore specification
