Empire Motor Sports was established in 1991 by custom car and truck enthusiasts who demand the very best for their trucks. The Empire team began making custom sill plates and their famous one-piece heater box covers for 1988 body style GM trucks. Empire manufactures a full line of billet interior pieces for '64-'05 GM trucks, and are a licensed product manufacturer.

All billet aluminum accessories are manufactured in-house at Empire Motor's facility in Rancho Cucamonga, California, by experienced craftsmen. Empire team machinists have been machining aerospace parts for over 40 years and their expertise in this area insures excellent quality. All of their billet aluminum 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 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" and are the world's largest manufacturer of billet aluminum parts for Chevy and GMC trucks.
