Dual airbags went into redesigned Wranglers, introduced in early 1996 as '97 models. A revised suspension that did away with the leaf springs was also new. Appearance did not change so much, except for installation of round headlamps. Three trim levels went on sale: SE, Sport, and Sahara. The new canvas top, with plastic windows, folded more like a traditional convertible's roof. A hardtop with full metal doors and roll-up glass windows was optional. Wheelbase was again 93.4 inches, and overall length was identical to that of the earlier model. Powertrains were as before: a 4-cylinder engine in the SE, and a 4.0-liter inline six for both the Sport and Sahara. A 5-speed manual transmission was standard; 3-speed automatic optional. Command-Trac 4-wheel drive was standard, and antilock brakes were optional only on the Sport and Sahara.
