M-38A1 Army Jeep
The M38A1 Truck, Utility, 1/4 Ton, 4x4 was introduced in 1952 as the military improvement upon the M38 Jeep. The M38A1 was manufactured by Willys where it was known as the Model MD.
The M38A1 featured rounded front fenders, a contoured hood, two-piece windshield, top-mounted windshield wipers, and a new "Hurricane" F-Head 4-cycle, 4-cylinder engine and Warner T90 transmission. It had a crew of one and could carry three passengers or 500 pounds payload.
The M38A1 military jeep is the model that inspired the CJ-5 civilian jeep. It differed from the CJ-5 in that it had a stronger frame and suspension, reversed front spring shackles, standardized military instruments, and 24-volt electrical system. A provision for a machine gun mounting post was installed on the floor of the body tub.
The model M38A1C was modified as a platform for the 106mm recoilless rifle.

The production history of the M38A1 jeep began 28 Jan 1952 and included four companies in addition to Willys-Overland, the developer and original manufacturer. Willys Overland became Willys Motors after its acquisition by Kaiser in 1953. Ford of Canada built the M38A1 CDN version as did Kaiser-Jeep. Finally, an affiliate of Kaiser in Holland assembled M38A1 jeeps in Rotterdam using US-made parts. In total, a little over 100,000 M38A1 military jeeps were produced, about 80% for US military use. The M38A1 military jeep was replaced in the 1960s by the M151 jeep.
Original M38A1 engines have a block number embossed in the form MDnnnnn or R MDnnnnn, the latter for replacement blocks. Small design differences during the production life of the M38A1 military jeep included:
