what's your budget?? the more we know, the more we can help...
Lots of companies make lift kits or blocks or springs to bring your ride height up a bit, but unless we know what you are willing to spend, and what type of driving you are going to do, we can't tell you much of anything.
If you plan to go wheeling like most of us here, then a different setup will be suggested... if you just want a big truck and do all street driving, then we'll suggest something completely different.
Best thing I can suggest right now is a 4" shackle flip in the back and 56" (I think) rear springs in front... that will give you more flex all around and give you 4" of lift all around.
