Arrowmax 48P 38T 7075 Hard Pinion Gear - AM-348038

The Arrowmax AM-348038 is a 48 pitch 38 tooth pinion gear machined from 7075 hard aluminium, designed for use in 1/10 and similar scale RC car drivetrains where a lightweight yet durable gear is needed. Running 48P gearing is common across a wide range of competitive and club-level electric RC cars, and the 38 tooth count makes this a solid choice for tuning your gear ratio toward higher top speed on longer, faster tracks. The 7075 aluminium construction gives this pinion gear a significant hardness advantage over standard 6061 alloy parts, helping it resist wear under repeated high-load use.

Key Features

• Machined from 7075 hard aluminium for greater wear resistance compared to standard aluminium pinion gears
• 48 pitch (48P) tooth profile matches the most widely used RC car spur gear standard in 1/10 scale electric racing
• 38 tooth count suited to higher top speed gear ratio setups on open or long-straight track layouts
• Part number AM-348038 for straightforward reordering and compatibility checking
• Lightweight aluminium construction reduces rotating mass in the drivetrain compared to steel alternatives

Compatible With

• Any RC car or buggy running 48 pitch (48P) spur gear and a motor shaft sized to match this pinion bore
• Commonly used with 1/10 scale electric touring cars, buggies, and stadium trucks running 48P gearing
• Compatible with brushed and brushless motor setups where a 48P pinion is required
