I have spent a considerable amount of time investigating what leveling kit I wanted to use on my 2016 F-350. It boils down to either a hockey puck like bracket for the springs with a similar set up for the front shocks that would allow you to use the existing shocks or jumping into the deep end and getting taller springs and matching shocks.
I figured in for a penny, in for a pound, and decided to get the taller springs and new shocks as the factory shocks are pretty lame. One of my overlanding buddies with a similar rig has also spent considerable time looking into the same upgrade and he brought up a good point. It turns out that some of the manufacturers, Carli for example, uses a smaller diameter "wire" to make their springs and the result is that you give up some of the load capacity of the truck in exchange for a softer ride. I had no interest in that so I contacted several manufacturers and to make a long story short I decided to go with Bilstien's leveling kit with matching 5100 series shocks.
The truck now sits more or less level (there is about a 3/4 inch difference now instead of almost 3 inches). The ride is nice and firm and I'm happy I made the upgrade!
Here are a few pictures ...
