Use a 3.5" lift so the drivlines don't have extreme angles. If you need more lift for larger tires use a 1-3" body lift or trim the fenders. James Duff makesa real good 3.5" lift kit. I tried Wildhorses first and wasn't pleased. Got the Duff set-up and its a smoother ride and flexes further. Its not hard to install the lift, the hardest part is the c-bushings, you have to tighten the bolts up evently on both sides are equal. Do this by connecting the radius arms to the axle and have the ends touching the ground. While tightening the bolts in an X pattern going from one side to the other if you see one of the arms lift, go to the other side and tighten it up to equal. Keep the ends touching the ground, this way you know its level. Other than that everything comes apart and goes back together the way it came out.
