The Willys-Overland CJ-3A was introduced in 1949, and was in production until 1953, when replaced by the CJ-3B. It was powered by Willys' L-134 Go-Devil four-cylinder engine, with a T-90 transmission and Dana 18 transfer case, a Dana 25 front axle and Dana 41 or 44 rear axle. It featured a one-piece windshield with a vent, and wipers at the bottom. The CJ-3A had beefed-up suspension (10 leaf) to accommodate the various agricultural implements that were being built for the vehicle. Another difference was a shorter rear wheelwell (the wheelwell from the top front edge to the rear of the body is on the 3A compared to on the 2A) and moving the driver's seat rearward. As of 1951, a Farm Jeep and a Jeep Tractor version were offered; the latter was very bare-bones, for field use only, and featured a power takeoff.
