Arrowmax 48P 78T RC Spur Gear - AM-348078

The Arrowmax AM-348078 is a 48 pitch, 78 tooth spur gear designed for use in RC cars running a 48P drivetrain setup. Spur gears are a core part of the transmission, transferring power from the motor pinion to the drivetrain, and selecting the correct pitch and tooth count is essential for proper mesh and performance. The AM-348078 suits builds where a 78T 48P spur gear is required, whether as a direct replacement for a worn gear or as part of a gearing change to tune your final drive ratio.

Key Features

• 48 pitch (48P) spur gear — must be paired with a matching 48P pinion gear for correct mesh
• 78 tooth count, which combined with your chosen pinion gear determines the overall gear ratio
• Suitable as a replacement RC spur gear when the original shows wear, stripping, or damage
• Gear ratio tuning: running a larger spur gear relative to the pinion lowers top speed and increases torque, useful for technical or high-traction tracks
• Arrowmax part number AM-348078 for accurate identification and reordering

Compatible With

• RC cars and buggies using a 48 pitch spur gear
• Any 1/10 scale electric RC vehicle drivetrain that accepts a 48P spur gear of suitable outer diameter
