Jeep finished production of the Jeep Wrangler JK in 2018 but they also started production the new Jeep Wrangler JL in, you guessed it, 2018.
So needless to say, there was bound to be a bit of confusion for some people who weren't up-to-date on their Jeep generation code knowledge. So let's clear things up and answer a question that comes up often:
1. One of the quickest and easiest ways to tell them apart is from the front, specifically the 7 slot grille.
The previous JK generation Wrangler has 7 identical vertical slots.
The newer JL generation Wrangler has the same 7 vertical slots except the outer most 2 slots curve around the headlights.
2. As long as you're comparing stock Wranglers, another way is to look for fender-mounted turn indicators. The New JL Wrangler has them integrated into the fenders whereas the previous JK does not.
3. The new generation JL only has push-button start versus the previous JK has a traditional ignition where you have to insert the key!
