The Rubicon model is the most off-road focused, with features such as heavy-duty axles, locking differentials, and an electronically disconnecting sway bar.
The Jeep Wrangler JK was offered with two engine options: a 3.6-liter Pentastar V6 engine and a 3.8-liter V6 engine. The 3.6-liter Pentastar V6 engine is more powerful and efficient, delivering 285 horsepower and 260 lb-ft of torque.

Transmission and Transfer Case

As for the transfer case, the Jeep Wrangler JK came with either a part-time 4WD system or a full-time 4WD system, depending on the model and trim level. The part-time 4WD system allows the driver to manually engage or disengage the front axle, while the full-time 4WD system provides constant power to all four wheels.
