The Rubicon adds 17-inch alloy wheels, special tires, off-road suspension, an electrically controlled antiroll bar that can be disconnected for more wheel articulation while off-road, electronically locking front and rear differentials, a stronger front axle, a special low-range transfer case and rock rails. The Rubicon also features equipment unrelated to its hard-core off-road abilities, including acoustic insulation under the hood, automatic headlamps, air-conditioning, leather-wrapped steering wheel and satellite radio (optional on Sport).
