Who We Are

In 1950, Diesel Injection Service Co., Inc. began offering superior original equipment diesel parts and services. Today, the Diesel USA Group continues this proud heritage by offering the same quality OEM brand name parts and components for most all makes diesel applications and turbochargers.

When you need critical diesel engine components, you need the best products from the best source. Using OEM parts is a wise choice, but you don't have to pay more to get them from a Vehicle OEM dealer. The name brand products that make your diesel's engine perform best can usually be obtained for less from the "Component OEM Distributor," and that's Who We Are! We provide products for most diesel applications including charge-air coolers, turbochargers, fuel injection systems, electrical components and filtration/additives.
