Affordable. Replacement. Steel.

 

Revolutionary Design Meets Robust Durability
Jesel engineers have combined the innovative features of our Pro Aluminum Rockers with the unmatched durability of our Pro Steel Rockers. Jesel Sportsman Steel Shaft Rockers offer engine builders the ultimate solution in high strength steel rockers, available at an extremely affordable price. These rockers can be seamlessly integrated as an upgrade to existing Pro Aluminum shaft rocker systems or ordered as standalone components.

Optimized for Performance and Longevity
Every Sportsman Steel shaft rocker is built with the same high quality components as our Pro Aluminum series, but enhanced for superior durability. These rockers feature a .625" wide body with an ultralight slot to reduce both weight and moment of inertia, making them perfect replacements for Pro Aluminum bodies.

Advanced Features and Options
Jesel Sportsman Steel Rockers are equipped with a .360" wide non-needle valve tip roller and a cup style tool steel adjuster, designed to endure high lift and high spring pressure applications. Optional upgrades include needle bearing nose rollers and ball style lash adjusters, further enhancing their performance. The precise rocker geometry minimizes roller movement on the valve tip, while the premium alloy steel construction and thorough hardening heat treatment, topped with a black oxide coating, ensure years of dependable service and corrosion resistance.

The Ideal Choice for High Pressure Applications
These rockers are specifically designed to excel in extreme conditions, making them ideal for turbocharged, supercharged, nitrous, endurance, and marine engines.

Our Rocker Story

When Chevrolet introduced its small-block V8 in 1955 one of its highly praised features was its lightweight stamped steel rocker system. With little more than a factory Duntov solid lifter cam a 7,000rpm redline was realistic. This economic valvetrain had its limits though. As long as mild seat pressures of around 100 pounds were used with low-lift hydraulic or flat tappet cams, life was good. As aftermarket cam manufacturers started grinding higher lifts, the rocker’s shortcomings began showing up. First, the rockers bottomed-out on the rocker studs because the slots were too short, then as spring pressures increased the studs pulled or broke out of the head bosses. The fixes came both from the aftermarket and GM.
