These High Energy™ Die Cast Aluminium Roller Rocker Arms for AMC V8 290-401; Ford V8 289, 302-351W; and Oldsmobile V8 350-455 applications are perfect for street and moderate race use. With a 7/16" stud diameter and 1.6 ratio, the die cast, larger-than-stock body of the rocker arms is made of aluminium for superior strength with light overall weight. High Energy™ Die Cast Aluminium Roller Rocker Arms from COMP Cams® are an affordable option that feature a die cast, aluminium body with a needle bearing fulcrum and roller tip. Designed to be stiffer and more durable, these cost effective rocker arms are capable of providing added valve lift while withstanding the rigors of a performance application. Their specially engineered fulcrum and roller tip create far less friction than sliding factory models to lower oil temperatures, thus improving both response and horsepower. Snap rings are used to hold the trunnion and bearings locked in place.
