The Jeep Wrangler generation produced for the 2007–2018 model years was the JK.
The JK was the Wrangler’s third generation. It was released in 2006 for the 2007 model year and represented a clean-sheet redesign of the body, frame, and suspension. Production continued until 2018, overlapping briefly with the arrival of the next-generation JL.
The JK is especially notable because it expanded the Wrangler lineup beyond its traditional two-door format. Jeep introduced the four-door Wrangler Unlimited, which had a wheelbase more than 20 inches longer and offered substantially more passenger and cargo room. That version became a major commercial success and helped make four-door off-road SUVs mainstream.
The JK also brought features that were less common on earlier Wranglers, including power windows, remote power door locks, navigation, and electronically disconnecting sway bars on some models. It is often confused with the JL because both can look similar, but the JL is the fourth generation and belongs primarily to the 2018 model year onward.
