Get the RC 4" kit and some 5/5 to 6/5.5 2" wheels spacers for the rear, light duty 2500 rotors up front. I had to run the .25" spacer up from to clear the spindles, but you can also grind the spindle down slightly for clearance. 265's won't rub and will look great on there. Good luck, lmk if you have any questions, I'll be more than happy to help you!
But an easier thing to do would be just get the lift, 2" wheel spacers for the rear and buy some 32/11.50 for the factory 15's. I wish that's what I would have done, esp with the wheels you have.
