Starting with the Sport's standard equipment, the Rubicon adds special 17-inch wheels, 32-inch tires, a heavy-duty Dana 44 front axle (matching the standard-spec Dana 44 rear axle), a shorter 4.10 rear-axle ratio (standard with the manual transmission, optional with the automatic), an upgraded transfer case with a lower crawl ratio, electronic front and rear locking differentials, an electronically disconnecting front sway bar, rock rails, automatic headlamps and under-hood insulation.
