it all depends on what you want to use it for. with that much lift, what size tires do you want to run? if your going to pre-run or race with it and beat the hell out of it then you will want a kit like the one from total chaos. pricey but worth it if your going to use for what its built for. http://www.chaosfab.com/balljoint http://www.chaosfab.com/uniball
if you want it for just a light off road truck then check out downeyoff-road.com
on my truck i am running a 2'' 4crawler body lift, fabtech upper arms and downey torsion bars in the front. total i got about 4'' of lift from the suspension. i could crank in more but the ride quality would really suffer. on the rear i am running the downey HD shackles. got about 1.5'' of lift from the shackle and i just recently installed the prerunner add-a-leafs and they are great. didnt change the hight but made the ride 100x smoother.
for tires i am running 235/75-15 and have no rubbing at all. i could probably go to 31s and still have no problems.
also check out http://www.race-dezert.com or http://www.dezertrangers.com/vb/ classified sections and you might score a deal on some used parts or long travel setup.
thanks man, i just bought a 3.5 in lift kit for 518.98. it is made by fabtech and has an add a leaf and new spindles. it recommends putting sway away 1636 torsion bars with it . so it should be pretty sweet. will i have to get extended brake lines?
i am not going to be hitting it hard or anything but i think this kit is designed for it. I ride dirtbikes and i always have to go offroad to get to where i am riding so it is nice to have it lifted and i always feel so gay with a short little truck so thats why i am doing it..
