Officially licensed by GM, Empire Motor Sports was established in 1991 by custom car and truck enthusiasts who demanded the very best. All billet aluminum accessories are manufactured in-house at their facility in California, by experienced craftsmen. Empire machinists have been machining aerospace parts for over 40 years! All billet parts are CNC machined from 6061T6 aluminum. Nothing is "punched", "stamped", or "cast". Unlike some of the other billet companies, Empire products are not made overseas and marketed as "made in America". Every part Empire makes is carefully designed, prototyped, fitted, checked, and re-fit until they are the finest products available. Empire Motor Sports is the one and only original home of "quality billet necessities".
