Pretty much. There is no point in spending the money on new torsion bar keys (and even more for the tool to unload the torsion bar). 2" in about the most you want to go, and stock keys will give you that much adjustment. The aftermarket keys are indexed to allow you to have more adjustment (plus they claim to maintain the stock ride quality which is bs), but going over 2" isnt recommended, some will go as much as 2.5'' but it will stiffen up the ride quite a bit. I don't know much about those shocks, but you are due for new ones and you will notice a good improvement in the ride once you do replace them.
