+1, you need bump stops. Going with 6" lift spring will NOT STOP YOUR TIRES FROM RUBBING. You can still flex the springs into a flat shape. As a matter of fact, with the right bump stops you could go down to a 2.5" lift spring and still run 35's with that body lift. I doubt that you will even need extended bump stops with a 3" BL. Just get some bump stops period. Bottom out your suspension to find out how much you need to limit it. Then get the proper bump stops. Going too long will limit your flex, but going too short will allow the tires to hit the body.
