Since their release, Jesel Sportsman Series shaft rocker arms have proven themselves to be the ultimate replacements for inadequate stud rocker assemblies on OEM and aftermarket cylinder heads. The 2024 aluminum bodied rocker arms are designed to withstand open spring pressures of up to 900 lbs., while maintaining precise valve lash settings. They 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 specific cylinder head to provide a bolt-on-and-go installation. If you're still spending aggravating hours adjusting your stud rockers only to have to repeat the procedure the next weekend, Jesel Sportsman Series shaft rocker arms are your solution. Choose a set designed for your application.
