A Brief History

Model Designation

The designation CCKW comes from model nomenclature used by GMC; the first C indicated a vehicle designed in 1941, the second C signifies a conventional cab, the K indicates all-wheel drive and the W indicated tandem rear axles. The term "Deuce and a Half" was applied to all 2½ ton cargo trucks. Including the DUKW, General Motors in the US produced 562,750 of these 2.5 ton trucks just prior to and during World War 2. The “X” in this case denotes experimental; the U.S. Army had not finalized the CCKW design when this unit was built, hence the addition of the “X” at the end of the model name.

The "Deuce and a Half"

The M35 family of trucks is a long-lived vehicle initially deployed by the United States Army, and subsequently utilized by many nations around the world. A truck in the 2-1/2 ton weight class, it was one of many vehicles in U.S. military service to have been referred to as the "deuce and a half." While the basic M35 cargo truck is rated to carry 5,000 pounds off road or 10,000 pounds on roads, they have been known to haul twice as much as rated. Trucks in this weight class are considered medium duty by the military and Department of Transportation. The M35 series formed the basis for a wide range of specialized vehicles.

The M35 started out in 1949 as a design by the REO Motor Car Company as a 2 1/2 ton truck that was later nicknamed the deuce and a half. The first vehicle in the family, the M34, was quickly superseded in military usage by the M35, the major difference being the M35's 10-tire configuration versus the M34's 6-tire "super-singles" configuration.

An M35A2 cargo truck with winch is 112 inches tall, 96 inches wide and 277 inches long, and 13,030 pounds empty 13,530 pounds empty when equipped with the front mount winch, according to dashboard data plates). The standard wheelbase cargo bed is 8 feet by 12 feet. The curb weight of an M35 is between 13,000 pounds and 16,000 pounds empty, depending on configuration (cargo, wrecker, tractor, etc.). Its top speed is 56 mph, though maximum cruising speed is approximately 48 mph.

Although the A2 version is by far the most common, there are four different iterations: Standard, A1, A2, and A3 iterations. These changes mainly had to do with the engine and transmission components. Standard M35 had a REO "Gold Comet" or Continental OA331 inline-6 gasoline engine. Some had 4-speed transmissions but most had "direct 5th" transmissions. The gasoline-powered deuces were built primarily by REO Motors, however, Studebaker also had a manufacturing contract from at least 1951 up into the early 1960s. Curtis-Wright also had a contract in at least 1958 to build deuce dump trucks with the Continental gas engine. The A1's had Continental LDS-427-2 non-turbo, and 5th gear was an overdrive. The engines were not reliable nor powerful. A2 trucks received the LDS-465-1 Multifuel turbo engines, keeping the OD transmission of the A1s. Through the years the trucks were upgraded to LDT (turbo clean air)-465-1A, B, C. The turbo was added more to clean up the very black exhaust on the Non Turbo engines, than to add power, the HP was only raised from 130 to 135 HP. The LDT-465 D was the last version of the Multi Fuel, it had a Quieter Turbo (non whistler) better head gasket sealing and head cooling.

Brake system is air-assisted-hydraulic six wheel drum with a driveline parking brake, although gladhands exist on the rear of the vehicle for connection to trailers with full air service and emergency brakes. Braking performance of the truck is similar to other power drum brake vehicles of this size. Each drum was designed with maximum efficiency in mind.

The "Red Ball Express"

The Red Ball Express was an enormous truck convoy system created by Allied forces to supply their forward-area combat units moving quickly through Europe following the breakout from theD-Day beaches in Normandy. The route was marked with red balls and closed to civilian traffic while the trucks were marked with the same red balls and given priority when on regular roads. The Red Ball Express supply plan originated in a 36 hour urgent committee meeting, and was co-designed by Lt. John Bridener Guthrie, Jr.
