Sorry about not getting back, I have been really busy. So I get alot of how did I lift my truck questions and here it is. I simply bought some 2" lift spindles with 2" spacers and 3" shackles. That was the four inch lift. I then built a drop set up and a 3" spacer instead of the 2" spacer, added a 3" body and another 3" in the rear for the 10" lift. I can go more in depth if needed. Just hit me up.
