The JK definition, explained, and more.

The End of the JK Series

Jeep models are often defined by specific acronyms, and oftentimes, there is some confusion about what they might actually mean. Throughout the years, Jeep has released various waves of models. Ranging from the aforementioned CJ series, down to the YJ (produced from the late 80s to the mid 90s), the TJ (from the mid 90s to 2006) and finally, the JK, which started in 2007, replacing the previous TJ series. The JK series ended in 2018, after 12 years of innovation.

For many jeepers, this truly marks the end of an era. The JK series has often been highly regarded as one of the company’s most successful forays into the market.

The halt of the JK series production also coincides with big changes in the company’s premier assembly complex in Toledo, as the plant will be retooled to focus on the production of other offerings, including Wrangler-based pick-ups, which will apparently roll out soon.

Identifying the Jeep JK Series

When you are looking into a JK model with 2 doors only, it might be quite easy to get confused with the previous TJ series, since there are many similarities between the two. Having said that, you might be able to easily tell a JK from a TJ if you actually know what you are talking about.

One of the biggest giveaways is most definitely the shape and style of the front grille. In the JK models, the grille is slanted back a little bit, and it has a rake, which makes the bottom stick out towards the top. This is also what makes the look of a JK’s front quite distinctive when compared to other older models. Some ever describe it as a pleasant vintage touch, which definitely enhances the aesthetic appeal of these Jeeps.

If you are looking for a Jeep with four doors, you are likely going to be looking at a JK. One thing that could get a little bit confusing is that the JK models can be branded differently. For example, there are several names out there, including Polar Edition, Willys, Unlimited, and others. Go past the branding and you will find that these are actually still JK models, in most cases!

There is a wide range of Jeep Wrangler JK models out there. The possibilities are truly endless, and whether you are in the market for a flexible 4-doors option, or you prefer the feel of a 2-doors instead, the possibilities are truly endless. In addition to that, you will also find many amazing Jeep Wrangler JK accessories to enhance your experience and truly bring your Jeep to the next level.

The Next Generation: JL Series

The Jeep Wrangler lineage will actually live on with a brand new series, which, you guessed it, will be marked by yet another two-letters acronym! The successive series, JL, is fresh off the shelves, so to speak (although you’ll need a very big shelf for a Jeep!). So far, it has shown the company’s commitment to  introducing quality features and innovative design appointments, contributing to an increasingly better experience tailored to the needs and preferences of the modern driver.

The 2-Letter History and Meanings

Ever since the late 80s, the “CJ” nomenclature became quite popular. Most people in-the-know are aware that it stands for “Civilian Jeep,” as to signify the fact that most models with that specific acronym actually were designed specifically with the civilian market in mind. Having said that, there are other acronyms as well, including “YJ,” as well as “TJ and “JK.” What does the latter mean? Long story short, these acronyms actually don’t really have a meaning, at least not one for the public. These are engineer codes, which are used by the company to keep track of their models, revisions and so forth.

More About the JK Series

The Jeep Wrangler JK series was actually introduced in 2007, and it has been going strong ever since it’s final production run in the year 2018. These models come in two or four doors options, making for extended flexibility, and making them perfect for various needs and applications. This is particularly amazing for people looking to travel in larger groups, or simply looking for a four doors layout, because previous models, such as the TJ series, actually only provided 2 doors options on the market.

Whether you are looking for a newer model, or you’re looking into an old-school Jeep series, you will certainly find that all of these beautiful Jeep vehicles have something in common. It is not by chance that this company has become synonym with this type of vehicle after all! What’s really interesting about Jeep is that the brand became a true cultural icon, partly due to the innovation of their designs, and partly due to their ever-increasing commitment to outstanding quality.
