Founded in 1957, Interstate was one of the world’s first Detroit Diesel Engine distributors. Our early focus was product service and support, and our service offerings remain one of the cornerstones of our business. With the addition of Allison Transmissions, that business quickly expanded to include engine and sales of automatic transmission sales and service.

Interstate then broadened its offerings to include Power Generation and Carrier Transport Refrigeration, expanding our territory to include nine Midwest and Western states. Industrial Bearing and Power Transmission products were added in 1992.

Interstate now consists of three operating units: Interstate PowerSystems, Interstate BearingSystems, and Interstate AssemblySystems. While the products of each unit differ, one constant theme remains – our uncompromising dedication to superior service and outstanding technical expertise.
