Well - Here goes my first post!  I have ordered a 2014 Sierra All Terrain Iridium Metallic.  It is set for production this week.  They are taking their sweet time as I ordered it over 3 weeks ago.  I have a leveling kit being installed when i take receipt along with a flares, tinting, and a topper (I know, I know).  It is a FabTech 2" leveling kit (FTS21039) I am also installing a 1.5" rear block kit. I personally really like the new wheels that come with the truck.  I was hoping to be able to keep the factory wheels and upgrade the tires to a Nitto trail grappler.  I am concerned about the effects of not modifying the offset.  Anybody have an opinion on rubbing, ride, handling, or other considerations with this modification?
Lastly, does anyone know if the front air dam (valence) provides any value after the vehicle height is modified?
