This product is a hardened steel 50-tooth spur gear designed to transfer power from the motor pinion to the drivetrain in high-performance Traxxas RC vehicles. The wide-face 1.0 metric pitch gear teeth provide increased strength and durability for handling high torque and brushless power systems. Its precision-machined design helps maintain smooth gear mesh and efficient power delivery while allowing drivers to fine-tune acceleration and top speed through gearing changes. The steel construction improves resistance to wear compared to standard composite gears during demanding driving conditions. RC car compatibility includes the Traxxas X-Maxx, XRT, Maxx, E-Revo VXL Brushless, and XO-1 models that use 1.0-module spur gear systems.
