Jesel adjustable shaft mounted aluminum roller rockers for cathedral port head: LS1, LS2, LS6 with 1.7 rocker ratio.
Jesel Sportsman Series rocker kits are designed to bolt on without any cylinder head modifications. 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 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.
note: Customers have reported that aftermarket valve covers along with some grinding and modification of the valve cover and, in some cases, the cylinder head may be necessary for clearance with these rockers arms.
