Picked up my Sierra last week, so decided to see what we could fit on it today. Installed the rough country 2” level and a set of fuel gripper m/t’s In a 35x12.50. After some trimming of mud flaps, removing bracket behind fender liner, and tying the fender liner back. Rubbing is gone. So if you’re not scared to trim some plastic it can be done. I think it looks good, let me know what you think. I knew worked on at4, couldn’t find anyone to confirm if would fit a standard level.
