The Rubicon is known for its extreme rock crawling ability. One of the reasons is its highly rated Rock-Trac System.
Due to its 4:1 low-gear ratio, Rock-Track delivers massive amounts of torque to go up and down sharp inclines as well as crawl over big obstacles such as rocks. It boasts a 73.1:1 crawl ratio with manual transmission that makes it easy to cruise over tough terrain.
