Since their release, Jesel Sportsman Series shaft rockers have proven themselves to be the ultimate replacements for inadequate stud rocker assemblies on OEM and aftermarket cylinder heads. If you are still spending aggravating hours adjusting your stud rockers, only to have to repeat the procedure the next weekend, then Jesel Sportsman Series shaft rockers are the solution for you. These 2024 aluminum bodied shaft rockers are able to easily handle today's aggressive springs and cam profiles. They are designed to withstand open spring pressures of 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 from their Sportsman Series rockers on countless applications, from daily drivers to bracket drag cars, various marine applications, and oval track dirt and asphalt racing. 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.
