If you go to Rough Country's wbsite, they show 2 kits for a 3" lift for cherokee vehicles. One is cheaper than the other. The more expensive one includes lower control arms but niether has u bolts. The zone offroad kit is priced between the 2 rough country kits, comes with u bolts and you can cheaply upgrade to their nitro shocks. From rough country, find out how much the u bolts will cost, add the gas shock upgrade and compare the cost. Probably very similar, shiping cost can also be a factor, don't forget that. You can't go wrong with iether zone or rough country, go with the one that lets you keep some of your money.
