you cannot put the spacers up front on a 2wd, the camber adjustment wont be anough to get it back into alignment, and theres nothing to really hold the spacer in its place.also the rack and pinion would sit in such a way that the tie rods would be on a very hard angle...and wear out fast. fabtech makes lift kits for the 2wd trucks, but the only one available for the latest gens are 6.5" kits, and they are 1400 bucks.
