Only thing I had to do was tweak the brake lines coming through the front fender wells and crank the torsion bars a bit to help with tire clearance. On the 'to do' list is to notch out part of the center console where the 4x4 shifter comes through to gain a little clearance. The bend in the shifter interferes a bit after the body lift. Took me about 1.5 hours start to finish by myself to do the lift. There is a brace in the middle of the truck underneath that I used a floor jack and some scrap wood to lift each side of the truck to install the lift blocks.
