What is CJ?

A Civilian Jeep or CJ was designed based on the military jeep models from World War II. The first design seen was in the year of 1945. The CJ was first manufactured by Willys-Overland.

Other manufacturers include Willys Motors, Kaiser-Jeep, and American Motors Company.

The CJ has 14 versions ranging from CJ-1 to CJ-10A.  It is an open-bodied vehicle. It also has a tapering nose design and circular headlights.

The CJ has a part-time four-wheel drive, rigid live axles, leaf springs on the front and rear end, and it can be driven without doors.

The CJ also had a two-wheel-drive variant called the DJ. CJ is also called one of the most successful utility vehicles ever made. The first model of a CJ, that is the CJ-1 was modified by using the regular military MB as inspiration.

It had a tailgate, canvas top to cover the roof of the car, lower gearing, and a drawbar.

The CJ-10 was more like a pick-up truck, equipped to handle a weight of up to 3000 kgs, and gave three different choices of variations of engines.

The CJ-10A was mostly an aircraft-pulling vehicle. But, the production of the CJ was stopped in the year 1986. 


What is YJ?

The Jeep Wrangler often called the Yuppie Jeep or YJ is the rebranding of a CJ vehicle.  It is one of the toughest and rugged jeeps and has greater stability and control.

Its square headlights provide for a very distinguishable feature from the CJ. The YJ sports a low center of gravity and heavy roller protection on the rear end and side.

Since it offers more stability the body of the passenger tends to roll less during turns. The YJ gives you a choice between two engines; a 4.2-liter inline-6 powerplant and a 2.5-liter 4-cylinder unit.

Both the engines come with a standard 5-speed manual transmission.

The front seats are foldable; thus, it makes entering the rear seats easy and also helps one transform the space into a cargo hold by folding the back seats.

 Although, the rear cabin did not provide for comfortable legroom.

It was one of its disadvantages. The inside of the Wrangler is fashioned with comfortable seats and the dashboard has been attached with 4 gauges as is the standard.

The front seats have short, narrow bottom cushions. Even though the model was exquisite, its manufacturing was stopped in the year 1996 and it was replaced by the Wrangler TJ.
