Jeep - Off-road Abilities

Off-road Abilities

Jeep advertising has always emphasized the vehicle's off-road capabilities. Today, the Wrangler is one of the few remaining four-wheel-drive vehicles with solid front and rear axles. These axles are known for their durability, strength, and articulation. New Wranglers come with a Dana 44 rear differential and a Dana 30 front differential (a dana 44 front and rear geared to 4:10 in the case of the Rubicon, also with lockers). The upgraded Rubicon model of the JK Wrangler is equipped with electronically activated locking differentials, Dana 44 axles front and rear with 4.10 gears, a 4:1 transfer case, electronic sway bar disconnect and heavy duty suspension.

Another benefit of solid axle vehicles is they tend to be easier and cheaper to "lift" with aftermarket suspension systems. This increases the distance between the axle and chassis of the vehicle. By increasing this distance, larger tires can be installed, which will increase the ground clearance, allowing it to traverse even larger and more difficult obstacles. In addition to higher ground clearance, many owners aim to increase suspension articulation or "flex" to give their Jeeps greatly improved off-road capabilities. Good suspension articulation keeps all four wheels in contact with the ground and maintains traction.

Useful features of the smaller Jeeps are their short wheelbases, narrow frames, and ample approach, breakover, and departure angles, allowing them to fit into places where full-size four-wheel drives have difficulty.
