2004 Yukon 4wd lift with 35's and NO RUBBING

I bought a Supreme Suspensions lift kit that to run my 35/12.50/r17 Ironman Allcountry MT tires on stock Z71 Tahoe wheels. I have 1" wheel spacers up front and 2" wheels spacers in the rear. no rubbing anywhere and it's rides great too. The kit came with 3" lift torsion keys up front, 2" aluminum coil spacers in the rear, and new shocks all the way around.
