Jesel 6.6 Duramax Forged Steel Rocker Arm Kit

KDD is proud to present our exclusive line of Jesel rocker arms for the 6.6L GM Duramax.  We had the honor of working with the world renowned valvetrain innovation experts at Jesel to develop the best rocker arms on the planet for the Duramax.   Engineered excellence. That’s what we consider the Jesel Pro Steel Shaft Rockers to be. Engineered to handle the immense cylinder pressures of a 3000hp Pro Mod engine 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 similar aluminum rockers. These advancements allow engine builders the opportunity to develop a more aggressive cam profile by utilizing a more stable valve train package.  Jesel Pro Steel Rockers are ideal for engines equipped with turbos, superchargers or nitrous where excessive exhaust cylinder pressures surpass the limits of a factory or aluminum rocker.
