Them 14-bolts are quite a bit stronger and heavier than the Dana 60's. If your worried about a stiff ride unloaded, go back with the rebuilt factory leafs and put a set of heavy duty air shocks on. Put some travel limiting straps on the front axle if your pulling eyes off the shocks. You can rebuild what you have and install helper springs or go with the 1-ton (4100) springs. I wouldn't go with the heavier new springs in the rear without replacing the front springs as well. How deep are your pockets is the question...Here's a couple of options to look at, the Super Spring with the active rollers are progressive allowing a smooth ride until they're loaded, they might suit your needs and not break the bank... https://www.sdtrucksprings.com/hellw...s-supersprings
