GR, I have a new set of Superlift 6" lift front springs collecting dust and I may have the drop pitman arm laying around somewhere too. All you'll need are longer Ubolts, a set of lift blocks and shocks. You can easily lift your truck, including tires, for less than this truck costs, not to mention ALL of the labor you would be getting yourself in for.
I'll make you an offer you can't refuse
And if you really want to top it off, my Sterling 10.25 with disc brakes is available as well.
