Introduced in 2007, the Jeep JK Wrangler was an instant hit with consumers. Like its rugged predecessors in the Jeep lineup, it was popular with off-roaders who wanted to play in the dirt. But it came with enough refinements to make it a winner for use on the road and for mall crawling.
So popular was the JK in its 2007-2018 run, in fact, that it became the marque's all-time bestseller. What does JK mean on a Jeep Wrangler? It's not an abbreviation. Rather, it merely served to designate the model type.
Jeep released the Jeep JL Wrangler after this hard-to-follow act. These models look similar, although there are subtle differences when you compare them side by side.
What's the difference? Our brief guide outlines the key Jeep JK vs. JL differences for easy reference. To explore these distinctions, we'll look at the interiors, exteriors and drive trains of these two Jeep models.
What is the Difference Between the JK and JL Jeep Wrangler?
- Interior
When investigating JL vs. JK Wrangler differences, looking inside each one will reveal some immediate disparities. Compared to the JK, the JL's interior has undergone some serious upgrading to make it more appealing to the many folks who will never take their Wrangler farther off-road than the nearest parking garage.

The JL comes equipped with an infotainment center that can be integrated with smartphones. Its flat dash has a slightly retro look, which contrasts with the modern digital instrument cluster on it. The longer wheelbase on the JL has allowed designers to provide extra room in the cabin, adding some comfort for drivers and passengers.
Most of the interior improvements will appeal mainly to those who use their Jeeps to cruise on paved roads. But those who do play in the dirt with their JL will appreciate the waterproof design of the JL's interior. Simply open the drain plugs and hose the interior off to clean it after use.
- Exterior
There has been some controversy about the more-sloped angle of the JL's windshield for improved fuel efficiency. But true off-roaders will love one key change in the windshield design. The new folding version on the JL can be easily and completely taken down so you can feel the wind in your face and your hair.
Another Jeep Wrangler JK vs. JL difference is the grille. The new JL grille has a somewhat more retro look, harking back to the classic CJs made from 1944 through the late 1980s. Also, the JK has a Jeep emblem on the grille while the JL does not.
Compared to the JK, the JL has also been on a reducing diet. Lower weight means better efficiency and higher speed. Lightweight aluminum has been used in the JL's hood, doors and fenders. Lighter, high-strength steel has been added in places.
Besides improving efficiency, lower weight makes it easier to remove the doors and hardtops. The JL's soft top is also easier to handle than the JK's, and the JL also has better bumpers that are stronger and have higher clearance.
The Wrangler JL Rubicon comes equipped with 33-inch tires, which are great for off-roading. In addition, larger flares on the JL mean you can use tires up to 35 inches in diameter. These big wheels will appeal to serious off-roaders.

- Drivetrain
Compared to the JK, the JL Jeep offers several changes in its engine, transmission and axles. These will be important to off-roaders as well as mall crawlers.
The JL still comes with the time-tested V6 3.6L engine. But now an optional turbocharged 2.0L four-cylinder or 3.0L Eco-Diesel V6 engines are available as well.
This option will provide superior torque. For off-roaders, torque is terrific. It can help you get over logs, rocks, mud, sand and just about anything else Mother Nature can throw in your way.
The transmission also has changed in the transition from JK to JL. The JL Jeep comes with an eight-speed automatic transmission, whereas the JK had a four-speed or five-speed automatic transmissions.
The new transmission has been refined to provide smoother shifting, which highway drivers will appreciate. Off-roaders will love the fact that the eight-speed can dig down deeper into a lower first gear, making it all the better for rock climbing.
The JL has a new electric-hydraulic steering system. This is said to provide better control at low speeds for traversing tough terrain. The Dana axles on the JL models are also a bit wider and stronger than those on the JKs.

The Bottom Line
All in all, the JL represents a more refined and sophisticated version of the JK. Although still a great vehicle for off-roading, the JL has evolved to fit well into the demands of urban and suburban dwellers.
Which one is better? That really comes down to your own situation. JL models will typically cost more than JKs because they are newer and come with more improvements. Either one could make a great vehicle for off-roading or everyday use.
