here is a cheap way (so to speak a cheat!!) to getting the 6" leafs for the rear, go to a junk yard get a pair of leaf packs from an s10 truck or even a blazer, i have a set actually dont think ill ever get around to using them as im not going to spend on a SYE and all that crap, but the widths of the leafs are same as stock jeep ones, and the only thing is center pins, 5/16 on jeeps and 3/8 on chevys, dont really matter as you keep the top one from your jeep pack, and the bottom one, take the 2 mids out of both packs and put chevy ones in middle of your jeep one reassemble and poof 6-7" lift, and yes this will work i was in the process of switching them but i realized(actually forgot) that i only had a 4" front lift!!!! that would look like a rail car heading to the track!!! good luck finding the coils for this idea but if you just dont want to go to a junk yard i paid 95 for my s10 leafs i would sell them to you (pending on where you lived) for 50 just to get them outta my hair!!!
