If you have coils thats the only thing u would have to worry about, i think. Depends on how you go about it. But other than that follow the instructions. If its IFS theres gonna be some welding and drilling, but other than that its pretty damn easy. me and friend did a 4" IFS lift a while back, wasnt hard, but took like 8 hours, so your gonna be in for a long haul. 
what did you have to weld?
