Engineered excellence. The brilliant engineers at Jesel have done it again!  We are proud to bring you our exclusive Jesel Pro-Steel Rocker System for the 6.7 Powerstroke, the worlds first and only aftermarket rocker system for this platform. Engineered to handle the immense cylinder pressures of 3000hp competition engines and strong enough to endure a grueling 24 hour road race with miles to spare. Through extensive engineering and FEA analysis, Jesel has designed a steel bodied rocker with less deflection and better moment of inertia than factory, aluminum, or any other rockers on the market. These advancements allow engine builders the opportunity to develop a more aggressive cam profile by utilizing a more stable valve train package, which allows the engine to make more power, higher in the RPM range.  

Jesel Pro Steel Rockers are ideal for engines equipped with turbos, superchargers or nitrous where excessive exhaust cylinder pressures surpass the limits of factory rockers. Also, any type of endurance racing such as oval / road racing or marine use would highly benefit from the fatigue resistance of a steel rocker arm, suitable for daily driving. 

CNC machined from a 4340 forging, the heat treated bodies are surface coated to resist rust and corrosion. A needle bearing valve tip roller along with a full compliment needle shaft bearing with thrust washers eliminates friction robbing horsepower and ensures smooth movement throughout the lift cycle. The rockers can be fitted with either our tool steel cup or ball lash adjusters for high lift applications.  100% designed and manufactured in the USA from start to finish.   

Kit includes: Left and Right tool steel rocker stand, 16 shaft mounded - forged steel roller tip rocker arms, 16 tool steel valve bridges, and oil plug.  

Note - oil plug may be used to plug the factory oil spray bar, as it is not needed with the Jesel Pro-Steel Rocker System.  The rockers receive adequate oil from the pushrods, and by eliminating the spray bar more oil is sent to where it's needed most - the bearings!
