Vehicle overview

The M606 was pretty much just the CJ-3B straight off the assembly line, with the same serial numbers as the civilian version. The military version took the heavy-duty options like larger tires and springs, a special rear bumper to hold the Pintle Hook and bumperettes, and a black-out lamp on the front left fender. The military CJ-3B also had a specific windshield not used on civilian models.

About the vehicle

One of the most unique differences between the M606 and the M-38 (which look similar) is the M606 has a 6-volt electrical system rather than the standard military 24-volt. The M606 also has a longer wheelbase, and has an F-Head hurricane engine rather than the Flat Head – this explains the “High Hood” look of the M606.

The CJ-3B was introduced in January 1953 and the M606 followed, produced at least into the mid-1960s. Relatively few of the M606s went to the U.S. military, but were exported.

Interesting facts

Jeep is an automobile marque of Chrysler (itself a subsidiary of Fiat). The first Willys Jeeps were produced in 1941 with the first civilian models in 1945, making it the oldest off-road vehicle and sport utility vehicle (SUV) brand. It inspired a number of other light utility vehicles, such as the Land Rover which is the second oldest 4-wheel-drive brand. The original Jeep vehicle that first appeared as the prototype Bantam BRC became the primary light 4-wheel-drive vehicle of the United States Army and Allies during World War II, as well as the postwar period.
