Here is a truck we did with just that package but with 22.5"s & 255's:
A package like that will range like stated above and your price will only reflect what options you want the package to have. I just sold a package for another guy doing the same thing and shipped with sway bars and dual shocks and all the steering upgrades was just over $5k. I can build you a more economy package with out some of the add ons for about $3k.
Again it all depends on what all you want for your needs and or concerns. When you are ready i am happy to build you a package and get it all shipped out.
