The Wrangler CJ series actually evolved from the Jeep Willys’ MB (1941-1945) vehicles which played a significant part in WWII. This is really the foundation and original nature of the Jeep. CJ and all other Jeep models were built around the MB. The ‘CJ’ in Wrangler CJ stands for ‘Civilian Jeep’. This range of 4x4 vehicles was named so because it was reconfigured from the military MB line. They were initially sold as a substitute to tractors and even came with different plows, power take-off attachments, and onboard elders too. From the CJ-2A to the CJ-8, this entire line spanned from 1845 up until 1968. The range of vehicles developed in comfort and size throughout those years.
Just like the military MB line, the Wrangler CJ started off with a four-cylinder, 60 h-p, ‘Go Devil’ engine but grew to embrace different engine options including six and eight cylinders. With around 40 years of producing the Wrangler CJ, Jeep became a resounding brand for selling durable and competent off-road vehicles. Americans made this image more famous with their adoption of 4x4 vehicles as everyday cars around the 1960s and 1970s. It is safe to say that the CJ series was a resounding success.
QUICK FACTOID: the iconic and peculiar seven-slot grille of Jeep first emerged with the Wrangler CJ-2A. The military line had a nine-slot grille.

Although none survived, a CJ-1 model was built and was a simple modification from the MB; civilian style canvas, drawbar, and tailgate were added. CJ-2 wasn’t so obtainable at retail but all the military properties were removed and it was basically an ‘Agri Jeep’. From the lessons learned in the past, the civilianized CJ-2A was created. It was fundamentally built for farming so accompanying attachments were available. Only two color variations were made initially but more options came up later.
