You could make a strong argument that out of all forms of racing, endurance racing is the most stressful on a valvetrain. Endless hours running at 9000+ RPM, constant gear changes and intense operating conditions compromise the fatigue life of even the best aluminum rocker arm. Through extensive engineering and FEA analysis, JESEL has designed a steel bodied rocker with less deflection and a better moment of inertia than similar aluminum rockers. These advancements in rocker design allow engine builders the opportunity to develop a more aggressive cam profile and valvetrain package. All JESEL Pro-Steel rocker systems are custom engineered for your specific application utilizing critical details such as spring rates, lobe lifts, pushrod angles and ratio requirements. The rocker geometry is designed to minimize roller movement on the valve tip. Each rocker body is manufactured from premium billet steel alloy and undergoes a through hardened heat treating process for durability. All of the steel components are processed with REM/ISF® Isotropic Superfinish to remove asperities inherent in the manufacturing process and to safely remove microscopic peaks, greatly reducing points at which stress fractures can begin. JESEL offers two distinct steel rocker body designs, the Mohawked J2S and the Pocket I-Beam J3S. The J2S style is designed more like our traditional Mohawk aluminum bodied rockers and is best suited for use with a threaded type adjuster. The J3S body can be custom engineered for applications where minimum rocker mass and lowest moment of inertia is a concern. Either design can be fastened using a traditional shaft and bolt mounting system or our new box style stand.
