i wish i got 33s right outta the gate instead of 31s. the stock 3.55s arnt too bad, ive barley noticed a difference in fuel mileage with my 4.56s gears over the stock 3.55s and 33s, but the acceleration and offraod performance is quite noticeable, if your thinking of getting 33s, just get em, when i lifted my jeep and got 31s i had no intentions of wheeling my jeep, just wanted a tough looking jeep, well i got hooked, and now im off to Moab in 6 months. get the 33s!
