Planning and Building the First Jeep

The Army had taken valuable lessons from the more than two decades of trial and error in their pursuit to create a lightweight, quick, military vehicle. These lessons led to the Army drafting a set of minimum specifications for this new vehicle, which were sent out to more than 130 vehicle producers. These specifications were as follows:

1. A driving front axle with 2-speed transfer case including provisions for

15. Special bracing for a pintle hook setup.
16. No aluminum to be used for cylinder head.
17. At least 4 cylinders.
