Although the WC series of trucks is similar in many respects to the M-37 series, there were a number of modifications to the basic WC design to make the M-37, among them:
The M-37 was in standard service with the US Military from it's introduction in 1952 until the late 1970's, and was used extensively in the Korean Conflict. By mid-1951, 11,000 vehicles had been produced, and by mid-1954, some 58,000 rolled off the assembly line. In 1958, a number of modifications to the design resulted in the new vehicles being designated M-37B1. From mid-1958 until the end of production, 47,000 M-37B1 vehicles were produced. Approximately 4,5,000 Canadian M-37CDN's were produced between 1951 and 1955. In total, between 1951 and 1968, 110,000 M-37s were produced. Spare parts for these vehicles were widely available and inexpensive to procure. Many deficiencies became apparent in the 1960s, including a tendency of the connecting rods to fail at high RPM's due to the long cylinder stroke of the engine. As the average speed of the vehicles in the military increased, these engine failures became common place due to the low gear ratio of the vehicle which was originally designed as a multi-purpose vehicle capable of transporting heavy loads of ammunition.
In the late 1960's, the Kaiser Jeep M-715, a very rugged looking truck that was well known for being under powered, replaced the M-37. As a result of the less-than-satisfactory reputation of the M-715, many M-37's stayed in service long past their phase-out date in the late 1960's, particularly with Reserve and National Guard units. Although the M-37 is also under powered at 90 hp, it is one of the toughest and most reliable trucks ever built for the military
