I have modded my Rubi, but even in stock form it had out perform a very modded "Sport." Go Rubi. it has better axles (Dana 44 front and rear) and a 4:1 T-case, and drives selectable diff locks. The best way to describe a Jeep is; When looking at what they are designed to do, nothing in the world can compare. When it comes to everything else, they leave a lot to be desired. They do not ride great and they are not roomy, but they are a convertible for the summer, 4wd for the winter and just a whole lot of fun to drive.
4:1 t-case, lockers, beefy axles
factory lift & winch option (Mopar has it for the Dodge Power Wagon).
