Now I could be wrong......but I don't think anyone makes 5" drop shackles for the rear. If by some chance they do, I wouldn't buy them. I would either do a flip kit, which will get you about 5-6" drop, or do a drop shackle/hanger combo which will get you about 4" of drop. If you were to somehow find 5" drop shackles and install them, it would destroy your pinion angle. On the shocks, it depends on how you want your truck to ride. If you don't mind it riding a little on the stiff side, I'd get Doetsch Techs. They are inexpensive, ride nice and tight, and last a long time. A lot of guys are running them and are very happy. As far as everything else on your list, it sounds like you have it all pretty much dialed in as far as parts. Might want to also consider a rear sway bar.
