Scraping sound on turns (metal on metal) with 275/65/20x9

[Big_Bertha_2016_2500HD]

i need help. i have 2016 silverado 2500HD that i just installed 20x9 wheels with 0 offset on 275/65/20 falken tires and i have the factory torsion keys turn a little up (was done before wheels installed) and after putting on the wheels when i mostly turn full turns and truck leans i hear an obnoxious scraping sound on the right side of front end of truck (while turning left).  i only hear it when i turn the wheel and truck leans. if i'm on level ground and turning it i hear no sound. i thought it was my rims scraping on lower control arm but it wasn't leaving any marks anywhere. i'm not sure if it's the shocks or what it is but when i turn the wheel to full lock i don't see where anything could be scraping on metal. please let me know what issue i'm having. i'm thinking of puting the rough country 3.5" leveling kit (or lift) on it to see if it stops the scrapes. it happens on both sides but more so on the right.

Could just be the pic angle but the shock in the last photo looks like the top of the shock is bent?

Crank your bars some more, you’re rubbing somewhere.

You need a leveling kit and likely some trimming to fit that combo.   Either that or find some wheels with a more positive offset.

i did crank the bars already before i put the wheels on it was cranked for a few months from dealership about 2" but the rubbing sound sounds like metal on metal but when i look under or have the installer look we didn't see anything where it looks like it could rub . i went to a mechanic shop and he said it was the metal plate behind the rotors that was touching the rotor when the truck lean in a turn but i checked that too . as far as the shocks it's not bent but i really do hope a 3.5 inch leveling(lift) kit from rough country will help it. it's getting to be annoying but mostly loud grinding when i turn left. not too much a right turn tho. i'm gonna have to figure something out.  thanks everyone for the inputs and i'm sure i'll have more questions about my truck in the future and i'll let everyone know when i get it leveled and the noise whatever it is goes away. thanks

so i found out the issue after taking it back to the shop that i got the wheels from it's the metal backing plate behind the rotor that covers the speed sensor that  was causing it to rub. so they pushed it back and grind down the rotor a little. thanks for your pointers as well.

Thanks for sharing this Big Bertha, I had a 2015 that did the same thing and I never could figure out what it was. I wonder if the shield got bent some how or if it's just a poor design, I will definitely keep this in mind if my 2018 starts making the noise.
