Metco Motorsports is now offering a precision-made supercharger pulley upgrade for the Hellcat! Like all Metco Motorsports pulleys, this pulley is an interchangeable unit that is based on a precision-machined, electroless nickel-plated steel pulley hub, an interchangeable pulley drive ring, and a stock-appearing front pulley cover. The pulley ring and cover are anodized in black, and all included fasteners are stainless steel or zinc plated.
