My 1999 F-250 had bags that I ran for years. Truck has a big sprayer in the bed and weights quite a bit and I fought finding the best ride for 15 years. Played with different shocks which kinda helped. Air pressure was hard to keep in the sweet spot with the constant fluctuation of the volume in the tanks.
Last year, I bought some heavy aftermarket springs for it.
Shoulda done that 15 years ago!
Much better ride over a wide load range.
Call ATS springs and see what they got. Good folks.
