Jesel Engineers have combined all of the features of our Pro Aluminum Rockers with the durability of our Pro Steel Rockers. Jesel Sportsman Steel Rockers provide engine builders with the option of high strength steel rockers at an extremely affordable price and can be ordered separately or as an upgrade to certain Pro Aluminum rocker systems.

The Jesel Sportsman Steel Rockers are assembled with all of the proven components of our Pro Aluminum rockers. Featuring a .625" wide body with an ultralight slot to reduce weight and moment of inertia. They’re designed to be a direct replacement for the current Pro Aluminum bodies and will bolt to existing stands. Featuring a .360" wide non-needle valve tip roller and cup style tool steel adjuster, the rockers can be optioned with needle bearing nose rollers and ball style lash adjusters for high lift / high spring pressure applications. The rocker geometry is designed to minimize roller movement on the valve tip and each rocker body is manufactured from premium alloy steel. A through hardened heat treating process along with a black oxide coating will provide for years of dependable service and corrosion resistance.
