The 0.6 Module Steel Pinion Gear & Spur Gear Series is designed for 1/10 scale RC cars and compatible drivetrain systems. These gears are used to transfer power from the motor to the transmission, helping provide reliable and efficient power delivery during acceleration and high-speed operation.
The series includes multiple pinion gear options, including 17T, 21T, 23T, 26T, and 29T, together with a 64T spur gear. Different tooth counts allow users to adjust the final gear ratio according to vehicle setup, motor characteristics, track conditions, and driving requirements.
The pinion gears feature a metal construction with a threaded side hole and M4 × 4mm set screw for secure mounting on the motor shaft. Different bore sizes are available depending on the model, including 3.175mm and 5mm options.
The 64T spur gear is designed to work with compatible 0.6 module pinion gears, creating a matched transmission setup for RC car upgrades, repairs, and custom builds.
