Sahara: 1997–2004 models came standard with 4.0 L, wider body colored fender flares, body colored rocker sills, optional 30-inch wheel and tire group and full steel doors. The Sahara also features exclusive decals, seats and trim. The Dana 44 rear axle and 3.73 axle ratio were optional. Standard features included an AM/FM stereo with cassette player and four speakers (later, a CD player replaced the cassette player, and seven premium speakers with center console-mounted subwoofer became standard), premium cloth seats, and alloy wheels. From 1996–2002 production, the seats were finished in a unique Camel/Forest Green color scheme.
