The 4-wheel drive Willys Jeep Truck, introduced in 1947 by Willys-Overland Motors, was similar to the Willys Jeep Station Wagon and the VJ-2 and VJ-3 Willys Jeepster. With model designations of 2T and 4T, these trucks were equipped with the 134 cubic inch Go-Devil flathead four-cylinder engine and the three-speed Borg-Warner T-90 manual transmission from the CJ-2A. The truck received a facelift in 1950 and became the 473, with the new "Hurricane" four-cylinder engine as an option. This model introduced the v-shaped front end with five horizontal bars, as well as an updated gauge cluster. The steps on the side of the pickup box were deleted. After 1950, the two-wheel drive model was discontinued. In 1953, the model designation became 475 and the grille bars were reduced to three. A 226 cubic inch six-cylinder 6-226 model was introduced in 1954, and sales of 475 models dropped considerably. The 6-226 was dropped in 1962 in favor of the 6-230 Tornado OHC engine.

The truck was originally sold as a 1-ton 4wd/2wd with a 1/2-ton 2wd becoming available in 1950 (model 473HT). The 2wd half and one ton trucks were discontinued in 1951 and sold as 4wd only. The load capacity was later upgraded but the truck was still sold as a 1-ton pickup.

Engines:

It was available with only one transmission, the Borg-Warner T-90 three-speed manual, with Synchromeshed 2nd and 3rd gear. A Spicer/Dana 18 transfer case was used on 4WD models. The heavy duty Timken 51540 was used in the early years of production, later being replaced by the Dana 53. The front axle was a Dana 25. With the 4-cylinder engines, a 5.38:1 gear ratio was standard, with 4.88:1 and 6.17:1 optional. With the 6-cylinder engines, 4.88:1 was standard with 5.38:1 optional.

Over 200,000 of these trucks were manufactured.
