More than just naming rights
What sets Wrangler Rubicon apart from the Sport and Overland models? Most notable are driveline changes aimed at toughness and crawling ability. Its axles are beefier Dana 44s and its low-range transfer case (called Rock-trac) provides a shorter ratio at 4:1, while its final-drive ratio is also shorter (4.10 versus 3.45). Further, Rubicon gets Trulock electronic locking differentials to help it find traction in really extreme conditions, and runs monotube dampers, along with a slightly higher ride height for better ground clearance. Finally, it gets an electronic disconnect for the front anti-roll bar to increase axle articulation, allowing it to find traction where lesser rigs would be hopelessly spinning a hung wheel.
