What kind of wheeling are you doin? If its regular rock crawling, the 3.73 will bring the suck. Basic trails, mud, stuff like that 3.73 will be fine. Personally, I don't do a whole lot of rock crawling, but when I do, 3.73 gears are not fun, especially with a manual tranny. But, as I can see, you live in CO, lots and lots of rocks, I lived in Durango for 5 years, I loved it, miss it like crazy,...but I digress!.... Gears are at the top of my list for sure. Even though the 2012 is a better engine, your low end gearing is still the same. BUt dont let your gear ratio prevent you from getting 35s. Get the 35s, regear later.
