Probably should not have made that blanket statement. See a lot of posts with people stating the ride is not acceptable on lifted, lowered and stock trucks. Agree that the old solid axle trucks will not ride like a car even with the extent I am going with my project. I had no load capacity built into my rear leaf packs as I will drive unloaded 95% of the time. My strategy for going stock height on a semi DD would be stock spring rate for front and rear replacement leaf packs. Softer if going with a progressive custom pack. If you are going to haul extra weight at times consider a helper bag setup. Universal setups are not costly. The bags can actually improve dampening when unloaded running at 10-15 psi. Unless you will be driving the vehicle hard and need the performance use a hydraulic shock not a stiff gas shock.
