GMC Model AFKX 4x4 Truck

The GMC Model AFKX, 4x4 Cab Over Engine (COE) truck was produced between 1939-1942 by General Motors Truck & Coach (Pontiac, MI). There were a number of chassis and body types:

  • AFKX-352, 1 1/2 - 3-ton 4x4
  • AFKX-502, 2 1/2-ton 4x4 Tractor
  • AFKX-804, 4-ton 4x4

The AFKX-352 was used with the Shop Van body, the AFKX-502 tractor's mission was to haul cavalry horses in stock trailers, while the AFKX-804 was used as an Army Air Corps radio van.

All AFKX models use the GMC 426 6 cyl. engine with a four speed (352) or five speed (502, 804) transmission mated to a two-speed transfer case. The AFKWX-353 is another COE design of the same time period which shares running gear with the AFKX, but the AFKWX-353 has two rear axles, rated at 2 1/2 tons.
