Jesel Sportsman Series rocker kits are designed to bolt on without any cylinder head modifications and in most cases still fit under a stock valve cover. The rocker geometry is preset and engineered using the common valve supplied with the particular cylinder head to provide a bolt-on and go installation. Thanks to Jesel’s extensive state-of-the-art CNC machining center and a closely controlled manufacturing process, these specially engineered cost effective rocker systems can be delivered to your door just days after placing your order.
