body lift has no affect on suspension. is yours 2 or 4 dr? i got myt body lift from summit racing. was 171 to my door 2 summers ago. the rear bumper can be lifted by zone off road brackets or cut and welding frame higher. you can get some spray paint and make the frame look better after it. its pretty simple. instructuons say take seat out but i didnt the cable will move by itself. the parking cable was the only trouble i had. all you will need is a floor jack and some blocks of wood to raise the jack up since your truck is lifted more. place a long piece of wood on pinch seem to spread the load out, i bent part of mine. you can do it with simple hand tools in drive way. i did mine when i was 15 with the help of some friends. spray all of the bolts a few times a day the week before you attempt to do it.
