Arrowmax 48P 39T 7075 Hard Pinion Gear - AM-348039

The Arrowmax AM-348039 is a 48 pitch 39 tooth pinion gear machined from 7075 hard aluminium, designed for use in 1/10 and 1/12 scale RC cars running a 48P drivetrain. Arrowmax produces this pinion gear from 7075-grade aluminium alloy, which is significantly harder and more wear-resistant than the 6061 aluminium used in many standard pinions. If you're looking for a reliable 48P pinion to tune your gear ratio or replace a worn part, the AM-348039 is a precision-machined option built to handle the demands of competitive and club-level RC racing.

Key Features

• 48 pitch (48P) tooth profile for compatibility with standard 48P spur gears used across a wide range of 1/10 and 1/12 scale RC cars
• 39 tooth count allows fine-tuning of your gear ratio for top speed or torque depending on track conditions
• Machined from 7075 hard aluminium alloy for increased hardness and durability compared to standard aluminium pinions
• Precision CNC machining ensures consistent tooth profile and accurate mesh with 48P spur gears
• Lightweight metal construction reduces rotating mass compared to steel alternatives while maintaining strength for race use
