Jeep - Willys M38A1
1952 - 1971
The Willys M38A1, or MD, was a four-wheel drive utility vehicle made by Willys from 1952 to 1971. It was widely procured by the U.S. military from 1952 until 1957, after which it was purchased by the U.S. Marine Corps and exported to foreign governments until the end of production in 1971.
About the vehicle
The M38A1 was the first vehicle to feature the round fender design that would later become the distinguishing body style of the CJ-5 (part of the Universal CJ series).
Produced first in 1952, following the retirement of the M38 model, the M38-A1 was re-designed as an “stand-alone” improvement, featuring round front fenders, a contoured hood, a two-piece windshield, top mounted windshield wipers, and powered by the new “Hurricane” F-Head engine and Warner T90 transmission.
The M38A1 (referred to by Willys as the “MD”), like the M38, had a frame and suspension that was much stronger than its civilian sibling, the CJ-5.
