No Modification / No Aggravation

Still spending aggravating hours adjusting your stud rockers only to have to repeat the procedure the next weekend? If the answer is yes, then Jesel Sportsman Series shaft rockers are the solution for you. Since their release in 2001, Jesel Sportsman Series shaft rocker systems have proven themselves to be the ultimate replacement for inadequate stud rocker assemblies on OEM and aftermarket cylinder heads. Easily able to handle today’s aggressive springs and cam profiles, these 2024 aluminum bodied shaft rockers are designed to withstand open spring pressures up to 900 lbs while maintaining precise valve lash settings. Both racers and engine builders have been rewarded with years of reliable, trouble free service of their Sportsman Series shaft rockers on countless applications from daily drivers to bracket drag cars, various marine applications, oval track dirt and asphalt racing.

Jesel Sportsman Series rocker arm kits are designed to bolt on with little to no 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 arm systems can be delivered to your door just days after placing your order.
