Hey, so Im pretty new to the Jeep world, I got my first jeep about a year ago being a 2006 65th Anniversary Wrangler.  I've tooled around a bit but im now ready to up it a notch.  I was thinking about putting 33" X. 12.5" tires because i like the look of the fater and wider tires.  If I were to do this, what else would I need to do to the jeep such as a lift and what not???  

there are many options there...for example,
RE 3.5" long arm
sye and cv shaft...recommended.
4.88 gears for the auto (.69 OD)/4.10 or 4.56 for the 6spd (.84 OD ratio)

33's will fit under 2" but may not have the "look" you're looking for, also the 2" requires fewer mods.
