go w/a 4"lift - some good ones out there - i have the HellCreek lift - it has a supple ride - complete kit - fits 33's no problem and great service... it comes w/the drop pitman arm (borrow the pitman arm puller from autozone) and you have to break the ball joint free from the small end of the old one - the kit is really complete and figure a weekend to do it (air tools made mine an 8 hour project...) if you dont want 33's at least go 32's - thats what i had on my old 91 sahara - w/the pro comp lift ... waaaaay to stiff a ride - also - order a new steering damper... you can lose the sway bar in front and the rear track bar if you want - i did and have no problems on the street - hope this helps - i know i had TONS of questions the first time i lifted a jeep but you'll be diggin the results and wanting more!!!!
Oh, almost forgot, you'll need a longer rear brakeline, you can get braided stainless for about $35 from Rubicon Express. You can get longer front lines (more expensive) or move the hardlines further down the outside of the frame.
my sye and shaft costed me a total of no more than 230 bucks.... that was the cost of the sye and fluid to fill it... the shaft i have is a front cherokee shaft... i sleeved over it with some 2" pipe to strengthen it
