Kelderman suspension

These posts have Kelderman in them.

I heard Keldeman is good suspension, but pretty expensive.
For my F350 I spend $300 for sulastic hangers and they made huge difference in empty drive comfort.
Suppose they improve ride with camper too, but not to degree you can feel.
My camper exceeds 6000 lb.

I have the Autoflex Ultra rear air suspension on my F350 DRW. It does not involve any permanent modifications to the truck frame, strictly bolt in. The install is a bit involved but I have been happy with the result. I run the bags about 35 lbs empty and 95 lbs with the camper (Bigfoot 10.4 weighed at 3600 lbs).

There is no kit made for the front unless you have 4WD, then Kelderman makes one. On the rear 4WD makes it easier, as the ride height is set higher, leaving more room for bags.

I have the “Two Stage” Kelderman on my dually. That’s the one that replaces the rear spring shackles with a big hinged bracket with air bags. I still have my rear leaf springs but they are floating on the bags. The main purpose is improving the ride while unloaded, and it works.
I don’t believe there is much benefit while carrying my camper.
The Two Stage isn’t terribly expensive and I like mine because my truck is also my daily driver to work and back.
