This spur gear is a critical drivetrain component engineered for high-performance 1/10 scale off-road buggies, specifically designed for precise fitment within the Kyosho ZX6.6 platform. Constructed from a durable, high-impact composite plastic, it effectively absorbs sudden shocks and impacts from the motor, safeguarding the transmission and other internal components from premature wear and damage during intense racing conditions. Featuring 76 teeth and a 48-pitch, this gear provides a key tuning option for adjusting your vehicle's overall gear ratio, allowing racers to fine-tune acceleration or top speed to gain a competitive edge on various track layouts and surfaces.
