I have a 2014 GMC Sierra with a 7 inch rough country lift, 35" tires and -12 offset rims, I tried putting 2 inch wheel spacers on but I couldn't turn my wheel fully without it rubbing on the inside of my wheel well, I was wondering if anyone knows if a 1.5" body lift will fix it or would I have to go with a 3"

 

When you say the inside of the wheel well are you rubbing the frame? If so the body life won't help.

 

It's not rubbing on the frame no,
