yeah, I agree with DPSHT and I suggest buying a kit, but if you want to do it on the cheap, bastard pack from an S-10 and TJ coil springs will get you excellent lift for around 160. Jeeps don't seem to like lift blocks much and a new spring pack is easy to deal with, and flexier. The only time I would use a block would be on a mud bogger where flex isn't very important.
