The Wrangler has retained a body-on-frame construction and solid axles. The vehicle is offered with three different four-wheel drive systems: Command-Trac, Selec-Trac, and Rock-Trac. Options available on all JL models (except Rubicon) include an anti-spin rear differential. The JL is designed to be more comfortable on-road[7] and has recirculating ball steering with electric power assistance.

The Wrangler is 2.5 inches longer overall than before, while the Wrangler Unlimited has grown by 3.5 inches.[8] The new Wrangler is roughly 90 kilograms (200 pounds) lighter than the Wrangler JK. Overhangs increase significantly with the new model having 29.2 and 40.8 inches front and rear.
