LS7 steel rocker arm kit! Our kit features steel rocker arms that offers better strength than the factory setup with a roller tip for reduced wear and friction on the valve tip. They are a great option for a quality set of aftermarket rocker arms without adding all of the unnecessary valvetrain weight that some of the other rockers on the market have. They will work with the factory rocker arm pedestals and are meant to be a bolt-on application for all LS7 engine applications. They will come standard with the Comp Cams trunion upgrade kit installed that provides quality bearings for a long life.
