thanks for the input I knew it was different but was not sure by how much. would I be able to clear 35's with the 2.5'' leveling kit and the 3" body lift.
also how much more dicult is it to put the body lift on my truck. also Im new to this but is anything else needed with a body lift (ie longer steering shaft or whatever) or should everything come with it.

 

The bodylift is pretty hard to install, I think local shops here charge like $550 for the 04+ trucks.....

They come with everything you need,

With the spacer and the bodylift you could run 35's I am pretty sure.
