Anybody lifted one? what type of lift? are the kits for a 2500 similar to a 3500?

Cognito leveling kit would be your best bet. Same suspension as a 2500hd. Can use factory shocks, or upgrade to bilsteins or pro comps. That and a dual shock setup and you will be set. let me know if you have any questions.

+2 on teh congito levelling kit. I would upgrade on the bilsteins
