These High Energyâ„¢ Die Cast Aluminum Roller Rocker Arms for Chevy V8 396-454 Applications are perfect for street and moderate Race use. With a 7/16" Stud diameter and 1.7 ratio, the die cast, larger-than-stock body of the Rocker arms is made of aluminum for superior strength with light overall weight. High Energyâ„¢ Die Cast Aluminum Roller Rocker Arms from COMP Cams are an affordable option that feature a die cast, aluminum 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.

Snap rings are used to hold the trunnion and bearings locked in place.
