The question on which Jeep Wrangler you should choose between JK and JKU depends on your needs and preferences.

If you love hardcore wheeling on abrasive terrains, you can’t go wrong with Jeep JK. The Jeep JK is preferred for off-road riding due to its a higher break over angle.

The higher break over angle allows you to slide over steep and rough obstacles with ease (although, skid plates and running boards are always a good idea). Jeep JK is also excellent for taking sharp turns and weaving tight corners.

However, if you have a family and want to carry them in your vehicle, the Jeep JKU is for you. It can hold more people and a lot of gear. Therefore, it all depends on your needs and what you like when choosing between JK and JKU Jeeps.


Now that you have learned the differences and similarities of Jeep JK and JKU, you can easily determine which one is suitable for your needs and preferences.

Keep in mind that Jeep Wranglers are among the strongest vehicles built to last for a long time. Once you buy the Jeep that you love, you can make modifications like changing the top or adding a roof rack.
