The term “Chevrolet 1.5 Ton Truck” most commonly refers to the Chevrolet G506 series of light-medium, four-wheel-drive military trucks used extensively by the U.S. Army and its Allies during World War II.

The G-506 was the official U.S. Army Ordnance Corps catalog designation for the 1.5-ton, 4×4 truck chassis built in massive numbers by Chevrolet from 1940 to 1945. It was a standard workhorse vehicle for the U.S. Army and Army Air Corps, and a significant portion were also supplied to the Soviet Red Army under the Lend-Lease program.

Design and Role

• Robust Drivetrain: The 4×4 drivetrain and rugged ladder frame chassis gave the G506 superior off-road capability compared to previous 4×2 commercial designs, making it ideal for the difficult combat theaters of WWII.
• Engine Reliability: The G506 used the famous Chevrolet “Stovebolt” inline-six engine, which was well-known for being durable, reliable, and relatively easy to maintain in the field.
• Compared to other Trucks: While smaller and more agile than the larger 2.5-ton GMC CCKW “Deuce and a Half,” the G506 still offered a respectable payload capacity and was less taxing to maneuver, making it a favorite for many missions.
