I wouldn't off road a 20 unless I was rolling on 40s. As for lifts, there are tons of choices. If just doing minimal wheeling and you don't plan on adding a lot of accessories (bumpers, winch, armor) you could just get by with a 2" budget boost. I have Old Man Emu springs on my Franken lift and am quite happy with it on my 2011 JKU.
