M38-A1 Illustration

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. With reversed spring shackles, military instruments, and a 24-volt electrical system, the M38A1 was a strong military work horse that was frequently fitted with a machine gun.

"Variants of the M38A1 include the “Original” round fender M38A1, M170 (Ambulance model), M38A1”C” (Rifle variant), USMC Variant, USAF DJ Variant, Nekaf Dutch Variant, Cdn Canadian Variant, Welding M38A1 Unit, and the First Year (1954) CJ5 (Civilian)." [1]
