IH M-3-4 1 1/2-ton 4x4 Truck

The International Harvester M-3-4 1 1/2-ton 4x4 Truck was produced for the U.S. Navy and Marine Corps from 1941 to 1944, during World War II. It was similar to the IH M-2-4 One Ton 4x4 Cargo Truck, but with a larger carrying capacity and a spare tire carried horizontally, behind the driver's door.

The M-3-4 1 1/2-ton 4x4 Cargo Truck was powered by a 6 cylinder OHV gasoline engine with a five speed transmission and a two speed transfer case.

There are three body variants of the M-3-4 truck. The M-3-4 had the standard cargo body while the M-3H-4 and M-3L-4 were the same cab and chassis carrying a US Navy designated fire/crash truck body, tank and pump. The fire/crash equipment was added to the trucks by IH sub-contractors (Beab/AMF), after which the US Navy designation for the truck was FFN-3.

Military trucks produced by International Harvester in the World War II era used a three part model number: M for Military, a second number indicating how many half-tons of off-road capacity, and a third number indicating the number of driven wheels. Example: M-2-4 is a one-ton model, 4x4. In some cases, an additional letter was inserted to further specify the model.
