Since May 2016, Diesels Unlimited has been establishing itself as a trusted company in the diesel as well as gas performance world. We are located in Elkton, MD and proudly serve the Tri-state area. We started as an independently owned repair facility and distributor of diesel products designed for Duramax, Cummins, and Powerstroke pick-up trucks. While we still are independently owned- we've expanded from strictly diesel performance and ventured into the gas world, specifically with LS and Coyote platforms. We specialize in transmission building and are able to build you a unit to suit any application, including Allison 1000, 4L60E, 4L80E, 6L80E, 6L90E, 4R100, 5R110W, 6R140, 47RE, 48RE, 68RFE, TH400 and more. We carry an extensive variety of performance products and are a proud vendor of popular brands such as AirDog, ARP, Atech, Autometer, BD, Danville, Edge, FASS, Fleece, Goerend, Holley, Industrial Injection, Mishimoto, PPE, Procharger, S&B, S&S, Valair, WcFab and the list goes on.  We recognize that all customers have different goals and different needs, and we strive to provide enthusiasts with the engine parts and accessories they need in order to get the power they want at a competitive price.
