Key Features

• Sintered Steel Shoe Technology: Features six sintered shoes made of high-grade cast-steel with a precision microfinish. This design ensures smoother engagement, better reliability, and a stronger "bite" than standard 3-shoe clutches.
• Superior Heat Management: Constructed from high-quality iron that is lightweight yet sturdy, allowing for rapid heat dissipation. This prevents the clutch from "fading" or slipping during prolonged use or high-torque situations.
• Maximum Torque Transfer: Engineered to handle the output of 6.5HP engines efficiently, reducing energy loss and ensuring your vehicle accelerates quickly and handles inclines with ease.
• Versatile Bi-Directional Drive: This clutch performs equally well in both clockwise and counter-clockwise rotations, offering maximum flexibility for custom engine layouts and unique drive systems.
• Flexible Mounting Options: Can be mounted "inboard" (sprocket toward the engine) or "outboard" (sprocket away from the engine), allowing you to align your chain perfectly with your rear sprocket.
