But don't you already have the factory air assist? Or are you talking about a different truck.
Otherwise I believe it's pretty much physically impossible to exert approximately 2000lbs of upward force to a 4500lb downward force that has compressed the suspension ___ inches and not have it recover a little less than half the height it lost.
Or at least it is how it has worked in every air bag truck I've had.
Its a simple calculation. Existing ride height unloaded + load = new ride height. Air pressure * x sectional area of airbags = upward force.
Now if your suspension was stout enough that it didn't compress alot, less than half of not alot isnt much.
When the pressure returns the loaded truck back to original ride height, the air bags are taking 100% of the added load.
Either way, the bags do smooth out the harsh suspension compression with some air in them.
