Custom built to your specifications.
From drag racing to endurance racing and everything in between, Championship Winning Racers rely on Jesel Pro Series shaft rockers to get them to the Winner’s Circle.
Our Pro Series rocker systems are built and custom manufactured to your specifications. Pro Aluminum Series rockers include premium standard features like a shotpeened surface finish, profiled rocker tail and a clipped-pin nose roller while allowing you to customize rocker ratio, adjuster offset and lightening options to your specific needs. Even the rocker stands can be custom ordered if needed to compensate for longer than stock valve lengths.
Used by top engine builders worldwide, Jesel rockers continue to set the standard by which all others are measured.
