The Jeep Wrangler JK and JL: An Overview

The Jeep Wrangler JK and JL are two distinct models of the renowned Wrangler vehicle created by Jeep. If you possess a 2019 or 2020 Wrangler, it is the JL model. Nevertheless, in 2018, both the JK and JL models were available simultaneously to facilitate a seamless transition to the newer JL model.

The Transition From JK to JL

The JL model, introduced as the newest generation of the Wrangler, coexisted with the JK model in 2018. This strategy enabled customers to select between the two models, minimizing any possible disruption in sales.

Key Differences Between the 2018 JK and JL Models

While both the 2018 JK and JL models share the iconic Wrangler design, there are several key differences between them. One notable difference lies in the engines they feature. The JK model is equipped with a 3.6L Pentastar V6 engine, whereas the JL offers multiple engine options, including an upgraded 3.6L Pentastar V6 and a 2L four-cylinder engine.

Another variation between the two models can be found in their transmissions. The JK comes with a five-speed automatic transmission, while the JL boasts an eight-speed automatic transmission, providing a smoother and more efficient driving experience.

The JL model also showcases more advanced technology features compared to the JK. Notably, the JL includes a backup camera and keyless push-button start, which enhance convenience and safety for the driver.

Additionally, the JL exhibits different lighting design elements. The JL headlights encroach on the grille vents, giving it a distinctive look compared to the JK. The JL also features front-facing indicator lights on the fender flares, further adding to its unique appearance.

When comparing the engine and transmission options of the JK and JL models, Jeep has made significant improvements with the introduction of the JL.

• The JK model offers the reliable 3.6L Pentastar V6 engine.

The transmission variations are another area where the JL surpasses the JK.

• The JK features a five-speed automatic transmission, while the JL boasts an eight-speed automatic transmission.
• The additional gears in the JL’s transmission provide drivers with smoother gear transitions, improved fuel efficiency, and a more refined driving experience overall.

1. Upgraded version of the 3.6L Pentastar V6 engine
2. Addition of a more fuel-efficient 2L four-cylinder engine
3. Upgraded from a five-speed to an eight-speed automatic transmission

Jeep has taken great strides in enhancing the performance and driving experience of the JL model compared to its predecessor.

Technological Upgrades in the JL

As automotive technology advances, manufacturers are constantly integrating new features into their vehicles to enhance the driving experience. In the case of the Wrangler, Jeep has focused on improving the tech features in the JL model.

One of the notable upgrades in the JL is the inclusion of a backup camera. This feature provides increased visibility and assists drivers when maneuvering in tight spaces or reversing. Additionally, the JL features keyless push-button start, making it more convenient for drivers to start their vehicles without having to fumble for their keys.

These technological upgrades not only enhance the overall comfort and convenience of the JL model but also align it with modern automotive standards.

Both the JK and JL models of the Jeep Wrangler offer LED lighting packages, which include various components like headlights, fog lights, daytime running lights, and tail lights.

For the JL model, aftermarket modifications have expanded the lighting options even more. One notable addition is the Pro-Series Vectorâ„?Grill, the first replacement grill for the Jeep Wrangler with an integrated LED lighting system. This innovative grill is compatible with both JK and JL models and comes equipped with LED lights for high beams, low beams, and dynamic daytime running lights.

Compared to stock lighting, the Pro-Series Vectorâ„?Grill offers several improvements. These include enhanced durability and style, increased water resistance, and brighter LED lights. Additionally, it provides independent controls for adjusting the light beams based on the driver’s preferences.

Moreover, owners of both JK and JL models can install additional lighting accessories for further customization. These options include color-changing halo lights and demon eye headlights, allowing Jeep owners to personalize their vehicles and add a unique touch to their Wranglers.

Evolution of Jeep Wrangler Models

Jeep has a rich history of producing rugged and capable off-road vehicles, and the Wrangler is one of their most iconic models.

The Wrangler lineage began in 1987 with the YJ model, which was produced until 1995. It was succeeded by the TJ model, which was in production from 1997 to 2006. Finally, in 2007, the JK model took the reins and continued until 2018 when the JL was introduced.

Interestingly, the initials “CJ” in Jeep CJ models stand for “Civilian Jeep.” This term was used to differentiate the civilian models from their military counterparts. The CJ models laid the foundation for the Wrangler’s design and off-road capabilities that are seen in the JK and JL models today.
