These replacement plastic pinion gears are specifically designed for Maverick Ion series 1/18th scale RC vehicles, offering a crucial link in the powertrain from the motor to the spur gear. Crafted from durable composite plastic, these 13-tooth gears are engineered to provide efficient power transfer while also acting as a sacrificial component to protect the motor and transmission in the event of severe impact or overload. Ideal for maintaining or tuning your vehicle, they ensure smooth operation and can contribute to a quieter drivetrain compared to metal alternatives, making them an excellent choice for repairs or routine maintenance.
