we just put a service body on our 1999 f350 dually 4x4... its of course a load so the truck is riding like its loaded (which it is) anyone have a suggestion of a product/ replacement spring that would upgrade it?

just go to Any spring shop and have them add a few leafs. Problem solved.

I would recommend Timbrens. Cheaper than either added leaf springs or airbags, and since you carry the extra weight all the time they are a good way to go. If you only carried extra weight occasionally, airbags would be the way to go.

I would track down a set of springs off an 05-07 F-350 dually. They bolt right in and the newer trucks had a higher payload. Surf craigslist, ebay, or some of the powerstroke diesel truck forums, seems that someone is always selling springs when they put a lift kit on their truck. Just remember that your payload is still limited by your tires and axle rating.
