Made from steel, its a metal shredders dream CAM with a 80's type tone. The fine tuners are added to the top to complete the CAM assembly. FYI: Your steel cam may look different than this. It may appear to be a one piece cam with the cam cage (the part with the 6 string hooks) as an integral part of the assembly. This was the original designed one piece cam. If you have this older type of cam, you will need to assemble a new version CAM assembly by combining these parts: 1 CAM, 1 CAM cage, 1 load lever, 1 pin and 3 cam cage screws to complete a new version cam assembly.
