Pro Series Aluminum Shaft Rocker Kit

The Jesel KPS-26196 is a Pro Series aluminum shaft rocker kit, engineered for high-performance SB Ford Z-304A applications requiring 2.080" stud spacing. These rockers are a preferred choice by championship-winning racers and top engine builders worldwide, setting a benchmark for valvetrain components. Constructed from a custom-blended 7000 Series aluminum alloy, these rockers offer exceptional mechanical properties. This advanced alloy boasts tensile strength at 300° that significantly exceeds industry-standard 2024 alloys, ensuring extreme durability and a lightweight valvetrain assembly. The design prioritizes low moment of inertia and utilizes FEA-designed bodies to minimize rocker body deflection, thereby maximizing lobe lift efficiency. The Pro Series systems are built to precise specifications and can be custom-manufactured to meet individual needs, with options for rocker ratio, adjuster offset, and lightening. Standard features include a shotpeened surface finish, a profiled rocker tail, and a clipped-pin nose roller for enhanced performance and longevity. Custom rocker stands can also be ordered to accommodate longer valve lengths.
