7041 18T 48P 2.3mm Bore Pinion

The Traxxas 7041 18T 48P 2.3 mm Bore Pinion Gear is a small steel gear designed for RC cars and trucks with a 2.3 mm motor shaft. With 18 teeth and a 48‑pitch tooth profile, it meshes with a compatible 48P spur gear to transmit power from the motor to the drivetrain. This pinion strikes a good balance between acceleration and top speed, making it suitable for a variety of smaller RC models. It comes with a set screw to secure it firmly on the motor shaft, ensuring reliable performance during operation. Adjusting the tooth count of this pinion allows fine-tuning of the vehicle’s gear ratio to optimize either torque or speed.
