How to Identify Jeep Wrangler Mods by Generation

When it's time to mod your Jeep Wrangler you're going to notice something really fast – there are a ton of names and trim levels to account for. You have strange code names, like YJ and TJ, and even more trim levels, like Rubicon and Laredo, so it can be a lot to handle sometimes. Fortunately, we’re here to help. In this article, we take you through how to identify Jeep Wrangler mods by generation, with the main focus being on identifying each Jeep generation.

Jeep CJ7 (1976-1986)

First things, we have to start with the CJ, which is what came before the mighty Wrangler. We’re covering this option because the CJ5 and CJ7 models laid the foundation for the Jeep Wrangler that we know and love today. Produced from back in 1945 to 1986, these Jeeps are loved by enthusiasts around the world. Plus, who doesn't love the sound of a Jeep with a 5-liter V8 in it?

You'll know you’re looking at a CJ7 or similar CJ model based on how dated some of the designs will feel. The windshield is flat, the interior is lacking in pretty much all amenities, and the body looks like it could be featured in an old-school black and white movie. Thankfully, a lot of this can be fixed with Jeep CJ7 interior parts and accessories.

You can also determine if you’re looking at a CJ7 by checking out the headlights. Unlike the first Wrangler generation that came after it, the CJ7 will have round headlights and a flat grille. It's hard to explain but if the Jeep looks like it could be in a World War II movie it's probably a CJ7 or an older model.

Jeep Wrangler YJ (1986-1995)

The Jeep Wrangler YJ hit the road in 1987 and stuck around for quite a while. If there's one quick way to tell you're looking at a Jeep Wrangler YJ, it's the headlights. Most Jeep Wrangler models across the vast pool of trim levels have round headlights. Well, not the Wrangler YJ, because this one has square headlights – not everyone agreed with that decision, either, so some aftermarket Jeep Wrangler YJ parts and accessories may cover them up or replace them with round lights. This can make it a little tricky if you don't know the other unique aspects of the Wrangler YJ. Aside from the headlights, the grille is another tell. Jeep went with grille slats that look almost bent in the middle. You'll also find that the YJ has slightly upgraded leaf springs compared to CJ models. For this reason, many CJ parts and accessories will work with the Jeep Wrangler YJ. When it comes to the engine options for this generation, the 2.5-liter inline-four and the 4.2-liter inline-six cylinder were the most common options. In later years, however, fuel injection started becoming an option so you may still be looking at late-model YJ if you pop the hood and see a 4-liter inline-six.

Jeep Wrangler TJ (1997-2006)

The late 90s brought with it the Jeep Wrangler TJ, which was produced until 2006. It received a lot of upgrades from the YJ and you'll notice them immediately when you hit the road thanks to the coil spring suspension that replaced the older lead spring options. Moving on to the interior, you'll find that it's comfortable, more spacious, and a lot more modern than the YJ. Still, it does come up short compared to modern models that may have navigation systems and other unique features. If you want to determine if you have a Jeep Wrangler TJ by popping the hood, it's fairly easy because this generation didn't come with a ton of engine options. In fact, you pretty much had to choose between the 4-liter six-cylinder and the 2.4-liter four-cylinder engine. Unfortunately, these engines are a little sluggish, so we recommend perking them up with a cold air intake for some quick horsepower gains.

Jeep Wrangler JK (2007-2018)

If you see a Jeep Wrangler driving by, there's a good chance you’re looking at the JK because they're some of the most common Wranglers on the road. What made the JK special right out of the gate was the four-door option – the Wrangler Unlimited. This trim was electric at the time because it enabled families to get in on the fun.

Other unique attributes that you'll find on the JK include a wider stance, bulky rounded fenders, and a slightly slanted grille. You'll also find that the turn signals are mounted on the front fenders instead of the grille. If you pop the hood you'll typically find one of two engine options. The earlier years (2007-2011) featured the 3.8-liter V6 and the final years of the generation got an upgraded 3.6-liter V6 that offered more power and fewer problems. When it comes to mods, the Jeep Wrangler JK has some of the best aftermarket support available.

You'll have no problem finding JK parts and accessories because this generation has more than 10 years of aftermarket support behind it. This is why lift kits, wheels and tires, and plenty of off-road mods are available for this model.

Jeep Wrangler JL (2018-Present)

The most recent model in the Wrangler stable, you have the JL. Any mods for the JL are referring to mods for the 2018-present generation. The beauty of the Wrangler JL is that you'll know you’re dealing with one the second you get behind the wheel. While the exterior remains rugged-looking and has that classic charm, the interior has the latest innovations ranging from Apple CarPlay, push-button start, heated seats, and much more.

Still, there are some noticeable differences between the JL and earlier models on the outside as well. The taillights are squared-off and LED and the headlights tend to be brighter LEDs as well.

You'll also find several motor options for this bad boy. Standard models have the 3.6-liter V6 but there are some crazy options like the 6.4-liter V8 in Rubicon 392. Plus, if you want to save money at the pump the 2-liter turbo has your back.
