This 80-tooth, 48-pitch spur gear is engineered as a direct replacement or tuning option specifically for the Kyosho ZX6.6 1/10 scale 4WD competition buggy. Crafted from a high-strength, lightweight composite material, it effectively transmits power from the motor's pinion gear to the vehicle's drivetrain, ensuring smooth and reliable operation under demanding racing conditions. Utilizing an 80-tooth spur gear offers specific gearing advantages, typically providing increased acceleration and torque output, making it ideal for tight, technical tracks or for reducing motor temperatures by lowering the overall gear ratio when paired with a smaller pinion.
