Made from high-strength heat-treated steel, it delivers outstanding durability under high engine torque and prevents gear stripping during off-road bashing. Precision CNC machined lightening holes reduce rotating mass for faster throttle response, also helps dissipate heat and cool clutch shoes for consistent long-run performance.
