did you still need the airbags at that point? to me the best suspension is one you build good enough you don't need air bags, and yes I did use them on my 98 f150 with my old pull behind trailer. changed to timberins threw the airbags in a corner of the garage and never looked back. I should dig them out and put them on the buy and sell one of these days.
I use the airbags to trim and level the truck and camper. The new rear springs are 6+1 leaf's, and rated 4400# each. The front springs were sagging so I replaced them with 3 leaf springs. After the new front leafs were installed, unloaded, the truck unloaded, sat 42" high at all 4 corners measured from the ground, to the wheel well center above the axles. The camper weight lowers the rear a couple inches and the airbags can now bring the truck carrying the camper back to level.
I am confused a bit, are you making it level or are you bringing it back to the empty hight, and if the latter was that level or a little high in the back like trucks should sit so they are level when they have the load on?
This truck is setup to ride level unloaded. If I put 2000 pounds of concrete in the bed, it drops down but is close to level. If I put a 3000 pound TC with another 500 pounds of our stuff in it, the truck will drop a couple inches even with those big springs which I am pretty sure provide more weight carrying capacity than adding a pair of Timbrens with bump stops. The left side of the TC seems to be heavier and causes a slight left lean. The airbags allow me to compensate for ride height and to correct the left lean. I get back to a pretty level, normal ride using the airbags. Headlights aren't pointing into oncoming faces.
