Are there any better shocks out there for the 06 GM 2500 trucks?

I have a set of Koni Adjustable shocks (Adjustable rebound only) on my Camaro. The Koni's are a step above the Bilsteins in the Camaro world and I was curious if there were any Premium Shock companys out there catering to our trucks?

I have read about the Ranchos, but I don't know if they rival Koni's on quality and durability and I also don't know how adjustable they are (1-way, 2-way, 3-way or 4-way).

Thanks for the help guys...

Koni dont list shocks for these trucks.
I have a set of Konis off a 1980's F--d Bronco I kept when I sold it.
Made some extentions for the rears so I could try them on the 2500HD.
I have Stock, Rancho 9000X (9 way adjustable which adjusts the compresion & rebound) & Bilstiens, the Konis seem to be the best of the these
Trying to make it ride better is always a work in progress
