All you need to get to a stage 2 is front coilovers and new rear shocks. You dont have to go with Pro Comps brand you can go with ICON, Fox, or Kings if you'd like they a;; make shocks for the Pro Comp 6" lift.
I would assume and take this with a grain of salt that the one's BDS sells with there kit would also work with Pro Comp's because I know both the kIng & ICONs will both work with either pro comp or BDS so i'd assume the Fox Shocks that BDS sells will work as well.
