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
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.
