wind up the torsion bars that will give you 2" lift then if you look around you can get 2" taller springs for the back off the long wheel base ones some of them come with something called a winter pack you need the springs of the one with a winter pack. you can also put a 1" body lift on them without having to extend anything.if you go bigger than 1" on the body lift its a big job lots of things need extending. hope this helps
