Willys Jeep Truck
# Willys Jeep Truck

The Willys Jeep Truck is a truck made by Willys-Overland Motors from 1947 to 1965. The styling and engineering of the Jeep Truck was based on Willys' existing vehicles, the Willys Jeep Station Wagon and the Jeep CJ-2A.

## Production

The Jeep Truck was introduced in 1947 as a 1-ton four-wheel drive truck with a wheelbase of 118 inches (2,997 mm). It was available as a pickup truck, a platform stake truck, a chassis cab, or a bare chassis. A ¾-ton two-wheel drive version became available by 1949.

The truck was restyled in 1950 with the addition of a V-shaped grille with five horizontal bars. In 1951 the Hurricane IOE four cylinder engine replaced the earlier flathead engine, increasing power from 63 hp (47 kW) to 72 hp (54 kW).

Optional accessories included an engine governor, a power takeoff, and a pulley drive. A "Dump-O-Matic" hydraulic hoist became available for 1957.

Over 200,000 of these trucks were manufactured.
