Arrowmax 48P 42T 7075 Hard Pinion Gear - AM-348042

The Arrowmax AM-348042 is a 48 pitch, 42 tooth pinion gear machined from 7075 hard aluminium, designed for use in competitive RC car drivetrains. Pinion gears at this tooth count and pitch are commonly used in 1/10 scale electric touring cars, buggies, and similar classes where precise gear ratio tuning is essential. The 7075 aluminium construction gives this pinion gear significantly greater hardness and wear resistance compared to standard 6061 alloy, making it a popular choice for racers running higher motor speeds or sustained track sessions.

Key Features

• 48 pitch (48P) tooth profile matches standard 48P spur gears used across a wide range of 1/10 scale RC platforms
• 42 tooth count allows fine-tuning of gear ratio for balancing top speed against acceleration
• Machined from 7075 hard aluminium for increased durability and resistance to wear under race conditions
• Lightweight aluminium construction reduces rotating mass compared to steel pinion gears
• Style code AM-348042 for straightforward reordering and compatibility checking

Compatible With

• Compatible with any RC car or buggy running a 48 pitch spur gear
• Typically suits 1/10 scale electric touring cars, buggies, and stadium trucks using a 3.17mm (1/8") or 5mm motor shaft — confirm your motor shaft diameter before ordering
