All American Billet Serpentine Kits are a great way to clean up any engine compartment. Our kits come standard with High Quality Accessories and are made in the U.S.A. Brackets are made from 6061-T6 aluminum, and come in Machined Finish, Polished, Chrome, our exclusive Silverline Series and Black Anodized. Our kits come with the option of two different pulley styles, Classic Pulleys (no holes or cutouts) or our original pulleys (with the triangular cutouts), at no additional charge.
