M38 1/4 Ton 4x4 Utility Truck
The M38 1/4 Ton 4x4 Utility Truck, also known as the Jeep M38, is a military vehicle produced by Willys-Overland Motors from 1950 to 1952. It was designed to replace the M38A1 model and featured several improvements, including a more powerful engine, a redesigned grille, and a new transmission.
The M38 was powered by a 2.2L L-head gasoline engine that produced 75 horsepower. It had a top speed of 65 miles per hour and a range of 300 miles. The truck was equipped with a four-wheel drive system with two-speed transfer case and locking differentials. It also had a heavy-duty frame and suspension system that allowed it to carry a payload of 1,000 pounds.
The M38 was used by the United States military in a variety of roles, including troop transport, reconnaissance, and cargo hauling. It was also used by other countries, including South Korea, Turkey, and Greece.
The M38 was a versatile and reliable vehicle that played an important role in military operations during the early 1950s. It is still used by some organizations today, including historical reenactment groups and military collectors.
