I could be wrong, but I was looking at the OP's goal as only wanting to soften the stiff ride, which is mainly from the factory leaf springs. I didn't read it as trying to save a buck. Not everyone wants a "leveled" truck. Maybe they don't want the added height, or they want to retain the factory rake....assumed he might be one of those owners, in which case, his plan sounds good to me
I do agree that shocks should be considered, but I don't necessarily think that a matched front/rear suspension pkg is absolutely necessary. Worst case is, he decides to add the front parts later. No big deal.
