I did the Cognito kit on my 3500HD, I went with the shock extensions to use the Rancho shocks that it came with.

I would not want the pickup raised any higher (as far as going with a full lift kit). It rides level and even with a heavy gooseneck load it stays pretty level. I turned the stock keys on my 2011 2500HD and I will never do that again. That is why I went with the Cognito set up this time. The ride is excellent and it looks excellent, I dare say OEM quality. The Cognito stage I bought was only like $750, the next stage up with the Fox shocks was $1100.
