Chevrolet G506

The G506 was the US Army supply catalog designation for a family of one-and-a-half-ton, four-wheel-drive trucks built by the Chevrolet division of General Motors, sold as the G4100 and later the G7100 series. They became the standard 1.5-ton 4x4 trucks of the US Army and Army Air Corps in World War II, and Chevrolet supplied most of the 167,373 such trucks the military bought, about 154,000 of them. Some 47,700 went to the Soviet Union under Lend-Lease. Power came from a 235 cubic inch overhead-valve inline-six making 83 horsepower, behind a four-speed manual gearbox and two-speed transfer case, on a ladder frame with GM banjo-type axles shared with the GMC CCKW. Bodies ranged from cargo and dump trucks to panel vans, telephone line trucks and the M6 bomb service truck, on three wheelbases.
