New to my billet line of Lightning parts is the all new never before made billet cover for your alternator! Thats right its completely replaces the cast one. Made from 6061-t6 like most of my products. Makes a statement and lets everyone know you aint playn no games. If you want the best for your truck you know where to go! Be sure to stay tuned for my billet pulley coming out also that pairs nicely with this.
