The Chevrolet G506 trucks were a series of 1 12-ton trucks used by the U.S. Army during and after World War II.


The G506 was a U.S Army Ordnance Corps supply catalog designation for the 1 12-ton, 4X4, truck chassis built in large numbers by the Chevrolet Motor Division of GM.[1] The basic G506 truck chassis were used for several different models that saw service throughout World War II and the Korean War.[2]

During World War II, The U.S. sent 151,053 1 12-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.[3]


Engine and driveline

The G506 used a Chevrolet BV-1001-UP 235 cu in (3.9 L) I6 gasoline engine, producing 83 hp (62 kW) at 3100rpm and 184 lbf·ft (249 N·m) at 1000 rpm. This OHV engine would run on 70 octane gas.

All models have a 4 speed manual non-syncronized transmission and a two speed transfer case.[4][5]


The G506 was built on chassis with three wheelbases, 125 in (318 cm) extra short wheelbase (XSWB) used only on the G7128 Bomb servicer, 145 in (368 cm) short wheelbase (SWB), and the 175 in (444 cm) long wheelbase (LWB). All models had 7.50-20” tires and dual rear tires.[4][5]
