Chevrolet G506 trucks

The Chevrolet G506 trucks were a series of $1 1/2$-ton trucks used by the U.S. Army during and after World War II.

History
The G506 was a U.S Army Ordnance Corps supply catalog designation for the 1.5-ton, 4X4, truck chassis built in large numbers by the Chevrolet Motor Division of GM. The basic G506 truck chassis were used for several different models that saw service throughout World War II and the Korean War. All of the G506 series trucks were powered by the Chevrolet 235 cu. in. 83 hp. six-cylinder engine mated to a four-speed transmission and two-speed transfer case. It had a wheelbase of 145 inches.

During World War II, The U.S. sent 151,053 1.5-ton trucks of the G506 type to Russia as part of the Lend Lease program. Russian supply capability improved dramatically in the spring and summer of 1943, mainly as the result of the American trucks that were arriving in large numbers.
