If you’re a hardcore fan of retro cars, you’ll love the CJ5 but be ready to have a tough time finding the parts since this model was discontinued long ago. On the other hand, CJ7’s spacious legroom and storage space, auto transmission, and improved performance will be more appealing to those who can afford it.
Here is our detailed comparison for you so you can easily make up your mind by the time you’re done reading this blog!
What is CJ5
CJ5, also known as Classic Jaguar 5 Speed, is a jeep manufactured by Kaiser Motors in 1954. It is a part of the CJ jeep series that ruled the market during and after World War II (1945-1986).
The CJ5 was the fifth generation of the series. The jeep is a civil version of the military jeep used during that period. CJ stands for “Civil Jeep”.
A Brief History of the CJ5
It all started with a competition across the USA to design a combat vehicle in 1940. The winner was Willys-Overland Motors and the result was the final 1941 MB, commonly known as the “Jeep”.
After the war, Willys adapted the design for civilian use and the 1st result was the CJ-2A (Civil Jeep 2A). In 1950, the company was acquired by Henry J. Kaiser and became Kaiser Willys Motors Inc.
CJ-5 came to revolutionize the contemporary market in 1954 and became legendary. The later improvements made the jeep even more popular until it was discontinued in 1984.
What is CJ7
CJ7, aka Classic Jaguar 5 Speed, is the later and improved version of the CJ5 jeep. It entered the market in 1976 and offered greater interior habitability along with improved stability.
With new innovations and a stylish outlook, the CJ7 took over the market and has been in production ever since.
With significant improvement over the previous models, CJ7 is rocking the automobile world even in the 21st century.
A Brief History of the CJ7
The CJ5 received a backlash after the Insurance Institute for Highway Safety (IIHS) arranged a TV program to showcase the safety issues of driving a CJ5.
The program pointed out that the CJ5 had a tendency to roll over in risky street conditions at relatively low speed.
As a result, the legendary CJ5 was discontinued in 1984, and a newer, improved, and safer version (CJ7) was introduced in 1976 under the ownership of American Motors Corporation (AMC).
Cj5 Vs Cj7: How They Differ
1. Overall size
The CJ5 is wider and compact in design. The narrow dimensions made it easier for the CJ5 to take tight turns. It was the perfect solution for the people who are always on the go.
The CJ7, in terms of overall size, including doors and the engine, is bigger than the CJ5. It is taller and longer, providing more space to accommodate more features. The “U” shaped door panel also made it easier to walk through.
2. The frame
The frame size of the CJ5 is a bit smaller compared to the CJ7. The narrower frame allowed the CJ5 to take tight turns comparatively easily. However, the smaller frame also made the car unstable at low speed.
CJ7, on the other hand, took full advantage of the bigger frame by providing more legroom and introducing revolutionary auto-transmission.
The improved chassis featured twin parallel cesarean lanes and tougher parts that increased handling.
The CJ5 had a shorter wheelbase that made the design compact and lighter. This is one of the reasons the car became unstable on-read.
The jeep offered an 83-inch wheelbase, 139-inches long, and 69-inches wide.
The longer wheelbase of the CJ7 (93 inches – 149 inches long, and 69 inches wide) gave more space to accommodate advanced features and provide extra comfort.
One other major difference between the CJ5 and the CJ7 is the cylinders used to power the engine. The CJ5 had 6 cylinders
The CJ7 came with 4 cylinders that provided better performance but consumed a lot of fuel.
The CJ5 used a series of engines to provide the necessary torque and horsepower for off-road driving.
It started with a 4 cylinder hurricane engine with a modest 7.4-to-1 compression ratio. In 1965, the manufacturer introduced a 160-horsepower, 225-cubic-inch Dauntless V-6 engine.
The V-6 was replaced by the 150-horsepower, 304-cubic-inch Dauntless V-8 engine that offered more torque.
The CJ5 also offered the 232-cubic-inch base on the six-cylinder line or 258 V-6 and 151 cubic inches inline 4-cylinder Iron Duke.
The CJ7 had all the engines like the CJ5, except the Dauntless V-6. The jeep also offered a 145 cubic inch, inline four-cylinder, and C240 Diesel Isuzu engine.
The CJ5 only came with a manual transmission. Many people installed a custom transmission system onto their jeep that can change the manual transmission automatically.
The bigger frame and wheelbase allowed the CJ7 to install the auto transmission system and made driving much easier.
7. Storage space
Due to the compact design, the CJ5 had less storage space too. Getting into the car was trickier and you’d have less room for your equipment. The jeep also had to compromise the rear seats to make adequate room.
The CJ7 provided more comfort and storage space than the CJ5. The jeep didn’t have to compromise the rear seats and could accommodate most of your equipment alongside providing better access to the vehicle.

Which One to Choose
At the end of the day, this depends on your personal preference. If you like the retro outlook and compact design of the CJ5, be my guest. However, keep in mind that the jeep was discontinued a long time ago, so you’ll have a harder time finding spare parts.
The CJ5 is great for tight trails and mud holes. We don’t recommend getting a CJ5 because of its tendency to flip over, which is potentially dangerous.
If you want more legroom/storage space, better performance, and auto transmission; and are comfortable with paying the extra money, we recommend you choose the CJ7. They are a better investment due to their stability and readily available aftermarket parts.
The CJ7 is perfect for tall drivers and people who are looking for a smoother ride. The debate over Cj5 Vs Cj7 is going on for quite some time and is not going to settle anytime soon, so get the one that you think is the best fit for you.
