Hey guys and gals! I am looking to level out my 04 2500 4x4 and was wondering what the best kit is, how much i should expect to pay, and how hard it is to install. Thanks for your help!:)

Go for the cognito leveling kit. PM Nor-Cal Nick on here for more info. I think the cognito UCA kit is the best on the market hands down. Install is really simple as well.
