The Willys M38 was manufactured from 1950-1952 with a production total of 45,473. The M38 was based off of the CJ-3A but with a beefier frame and suspension. The Jeep was also identified by Willys as an “MC”. The M38 had protruding headlights with a protective guard wire in the front, blackout lights, and an air vent in the base of the windshield.
Some features that differentiated it from its civilian predecessor were: a one-piece foldable windshield, bottom mounted wipers, lifting shackles, a pintle hook for towing and a fuel filler on the drivers side. The M38 also had larger tires, 7:00×16″. In order to improve ground clearance the M38 did not have an outside step like previous models. M38’s were endowed with specific equipment depending on the usage of the vehicle. Some of them had Ramsey winches or were outfitted with wading equipment and a breathing apparatus for fording bodies of water. A few had light dozing and leveling equipment though it would be rare to find an M38 with such add-ons.
Some of these jeeps were used in the Korean Theatre of Operations until the Korean War was over in the mid 1950s, then they were made for export overseas.
Another notable difference in the M38’s design was a water fording ventilation system and a waterproof 24 volt electrical system. The pioneer tools (shovel and axe) were moved to the passenger side of the vehicle, which were originally on the drivers side of the Willys MB of WWII.

I need this jeep can you please forward the details of it
Why is it so difficult to find photos of M-38 s in combat fields or anywhete in Korea ? People even say to me that M38s have not been used in Korea War. Can anyone explain that ? Thanks a lot
I have a 1952 M 38 Willys jeep. It has a double action fuel pump. This pump has defective diaframs. It is
Letting gasoline into the crankcase
The pump was manufactured by AC. Where can I get a rebuild kit???
Hi Gene, on the M38s, the center vent is bolted shut and not movable as it is on the 3A…
I have a 1952 M38 that has an odd feature. The windshield vent hinges at the top with a clamp on the inside bottom to secure it.
I feel it is correct for this jeep as it still has the original tires on it. It spent its life as a fire dept. vehicle at our local airport, and was always garaged. They made a few changes in the way of add ons, but the body is dent and rust free. Speedo reads 3,754 miles.
Prior to 1972 the airfield was military. The jeep came with a title transfer in ’72 to the local county motor pool.
Sure would like to find out about the windshield vent.
Thanks. Gene Small Sisters, Oregon
as a jeep fan I congratulate you for your rig. Keep it the way it is for centuries to come. you may end up conquering mars with it.
When rebuilding my “48” CJ-2A I needed to replace the frame, probably not too unusal? I found a beautiful replacement but had some of the mounts neatly cut off. Replaced the parts and began the rebuild. During the process I noticed the letters “MC” stamped on the frame in a number of locations and wondered what the letters were for.
Now I know, it’s an M-48 frame. Thanks for the info., it is a great help Do I now have a quasi-military jeep?
