I have a JKU with the 3.73 trac-lock although it's an automatic. I can stuff a lot into it and like the longer wheelbase. Can't imagine a two door but I also have two kids to stuff in there maybe that's why. I run a budget boost with 35's that measure out around 33.25 inches. The 3.73 is a bit more forgiving than the 3.21 gears. My only advice I can really give you, decide first what you want your jeep to do and or how you want it to look. One thing I have learned, it sucks paying for extras twice when you start changing modification. Either way, just enjoy it.
