I have a 2018 with a 7" lift with 37x12.50R20s ..... It rubbed on the corners of the bumper and the rear on the pinch welds .. I had to do a SoCal Mod on it, did some cutting on the pinchwelds, folded them back and cut the front bumper ... don't be scared to do the same ... the only other thing is is doing a body lift which I am actually going to do at some point ... nothing wrong with a body lift , don't let the bad stories about body lifts scare you from installing one on your truck ...

 

I’m not afraid to body lift the truck. I’ve done them before. I can’t do one with my Amp steps though. I’ve cut the bumper and the pinch welds already. I still rub :/
If I had about an inch to 1.5” I would clear. Who makes your 7” lift?

 

Here are the pictures of how much to cut on the body mount brackets ..

The first pick is the driver side rear mount that just needed a small notch cut out. The front mount needed a larger notch

The 2nd pic is the front driver side with larger notch

 

Here is another picture with the 1.5" body lift ... but I would just go with the 3" body lift to make sure you have zero issues
