In all honesty, unless you plan on lots of wheeling in some tricky terrain, a 2" bb on 31's will suit you fine. Its a Lil extra height and will allow you bigger tires and won't break your bank. That's why it's a budget boost lol. You'll be able to tell the difference as soon as you sit in it. My original bb was a set of procomp es1000s from 4wheelparts.com, I spent 35 a shock and 59 for all 4 pucks. So for about $200 I had my 2 inch lift. 4Wheelparts has some pretty good deals on shocks. Check them out.
