index keys and lift kits

I have an 05 Z-71 Suburban with a 6 inch lift. Anybody out there know if you can use the index keys along with the lift kit to get the nose level with the rear and get rid of the tire rub during sharp turns? I'm running 35 inch Cooper STTs.It didn't rub with the Nitto Extreme Terrains

Yes you can put aftermarket keys on with a lift we do it all the time here at work. Just got done with an 04 chevy 1500 installed a 6in RCX kit with keys an 37in mudgrapplers on 20's
