Earlier 1/2 ton trucks had an enclosed torque-tube driveshaft design that would not work with the conversion kit. Initially, the kits were only installed for Chevrolet and GMC in 3/4 ton and larger trucks, as the drive trains in those trucks accommodated the conversion. One of NAPCOвЂ™s selling points was that an owner could take off the kit, return the truck to a two-wheel-drive status, and re-use the kit on another truck from the same manufacturer. Because the kit was well designed and made for these specific trucks, installation could be done in 3-hours with minimal changes to the truckвЂ™s chassis.

They then could either have a dealer install the conversion or do it themselves. Owners would buy a two-wheel-drive truck and then order the Powr-Pak kit separately. The kits were available for Ford, Dodge, and Studebaker, but the biggest sales revolved around GMC and Chevrolet trucks. The firm switched gears after the war and produced peacetime machinery including the NAPCO Powr-Pak 4X4 Conversion. NAPCO was an industrial parts manufacturing company and during the war produced specialized parts for the war effort. When servicemen returned home after driving Jeeps in World War II, the demand grew for something similar for the domestic market, and NAPCO вЂ“ Northwest Auto Parts Company вЂ“ was a natural fit. Manufacturers were already challenged to make reliable, long-lasting work trucks and hadnвЂ™t seen the market or demand for four-wheel-drive trucks. This 1940 Ford Wagon had a Marmon-Herrington 4X4 after-market unit.
