Pro Shaft Rocker Kit

This Jesel Pro Series Shaft Mount Rocker Arm kit, MPN KPS-335125-6050, is designed for high-performance Small Block Chevy (SBC) engines using AFR Eliminator 210/220 series cylinder heads. The kit includes 16 full roller rocker arms with a 1.6 intake and 1.5 exhaust ratio, crafted from a custom blended 7000 Series aluminum alloy for superior strength and light weight. Key features include a shotpeened surface finish, profiled rocker tail, and a clipped-pin nose roller, all contributing to enhanced durability and precise valve train operation. The kit can be customized with various rocker ratios, adjuster offsets, and lightening options to meet specific engine builder requirements. Installation requires specialized knowledge of engine valvetrain components and is best performed by experienced technicians. This kit replaces factory rocker arms and is intended for performance applications, offering improved valve control and power delivery. It is crucial to ensure compatibility with AFR Eliminator 210/220 cylinder heads for proper fitment and function. Despite its high-performance nature, no specific dyno-tested performance gains are explicitly stated on the product page. However, as a premium valvetrain component, it is expected to contribute to overall engine performance and reliability in demanding conditions.
