F550 & adding Air Bags.

I have a 2000 Model F550 crew cab with GVWR of 30000#. Naturally it has quite a stiff ride. If I were wealthy enough I would love to have the Kelderman air ride suspension. Unfortunately I am not that wealthy! Now the question. I have been told that adding helper air bags, such as though used for leveling and/or increasing the load on some trucks would make for a smoother ride. Anyone know if this is true? I don't see how it could help but I am no suspension expert.

i put the firestone bags on the front of our ford chassis rv and run them at 20# with an automatic pressure pump , and it does help some with the expansion jouints in the pavement.

I use air lift air bags on my f53 and it is very close to your 550. I think the help comes from removing the pre load on the leaf springs. It makes a real difference on pavement cracks and the like,not ona chuck hole. I run about 30 lbs on the front. The Kellerman unit would be nearly 5,000 bucks a big bite for most of us.

Did you put the bags on the rear, front or both?

Front for now have the rear ones in back of jeep, did not have the equipment in tx to raise the back and remove the tires to install. Will install soon. I had both on last MH and thought they helped. I would emphasize they only help on rough spots on HW not on big chuck holes. I also use them because most gas MH are under sprung IMHO.
