IMX16391 38T Main Spur Gear

This is a 38-tooth main spur gear used in the transmission system to control how motor power is translated into drivetrain torque. It meshes directly with the motor pinion gear, meaning its tooth count plays a major role in acceleration, top speed, and overall gearing ratio. A lower tooth count typically gives more torque and quicker acceleration, while a higher tooth count leans toward higher top speed but reduced torque. The IMX16391 is a direct replacement part designed to restore proper drivetrain function when the original spur gear becomes worn, stripped, or damaged. It mounts inside the transmission assembly and works alongside the pinion gear and center driveshaft system to deliver power to the front and rear differentials.

Features:

• 38T main spur gear for RC transmission systems
• Designed for IMEX 1/16-scale platforms (Avenger, Slider)
• Directly meshes with motor pinion gear for power transfer
• Impacts acceleration and top speed via gear ratio tuning
• Durable molded gear construction for drivetrain use
• Restores proper drivetrain function when worn or stripped
• Replacement part for transmission maintenance and repair
