use this from Fleet Ford. Scroll down about 75-80 percent for front and rear spring ratings. Looks like 4000/4400/4800/5200/5600/6000 lbs rating on the 4x4 in all those years. Does your truck have the camper package or heavy service package ??

You won't find spring rating on the door tag certification placard...just FAWR/RAWR/GVWR.
Thanks JIMNLIN, that's what I was looking for. I have the camper package and snow plow package. I won't ever use a snow plow so I really don't need the heavy springs so I may look into have them changed or change them myself. A 4,800 lb. stock rating vs a 5,600 is quite a bit of difference so that may be where my problem is coming from.
I think I lowered the front pressure to 65 but left the rear alone. I think I'll experiment with the rear pressure before I spend any money.
Thanks for all replies.
