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 is basically a solution looking for a problem and a hobby tinkering with the truck and camper. All good.
we all look at things different and it ain’t always right but it’s alright.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.
Did you custom set the springs, so it rides level empty? Stock, the rear aways sits a bit high, so adding beefier springs would typically increase that. If so, why didn't you keep the normal spacing?
^They could vary we’ll be and likely are stock type replacements.
some Super duty’s of that era had a heavy front spring package. Call it a snowplow package or whatever. Came from the factory “leveled”. And rode like a lumber wagon. Had a bunch of early superdoodys in the fleet with this package. Looked like a 2” front port basically.
ahh ok, I was hoping with heavier springs you wouldn't need them, setting up the springs is always the best option.
