Just do an internet search on either energy suspension or prothane. You ought to be using smaller bumpstops up front and bigger in the rear. I think energy suspensions has low profile and ultra low profile for the fronts. You probably only need low profile for 0"-3" of lift IMHO. The rears you should be able to get away with 9.9104B or 9.9104R which just means either black or red. I am using these in the rear of mine, plus a piece of 2-1/2" square tubing as a n additional spacer. I am at 4-1/2" of lift. So you ought to be fine.
