Napco Four Wheel Drive Vehicles

NAPCO (Northwestern Auto Parts Company) was a four-wheel drive (4x4) vehicle parts manufacturing company founded in 1918 and based in Minneapolis, Minnesota USA. Besides four-wheel drive units, NAPCO also provided winches, auxiliary transmissions, tandem drive axles, hydrovac systems, and dump truck bodies.

In a partnership with Sherman Products Inc., NAPCO also produced a Front Wheel Drive (FWD) Assist kit for Ford 600 and 800 series tractors in the mid-1950s. Marketed under the name Sherman NAPCO, the kit did not sell in large numbers, as it was competing with the more common Elenco FWD Assist

The 4x4 business was eventually acquired by Dana Corporation, but the company survives as NAPCO International and still produces parts and equipment for the military.
