No metal at all just plastic... very Very small portion And that was just temporary because I will be doing the mud flap delete on it. And between the arm and tires I have about 3/16”.... I have flex the truck pretty hardcore To test out... and No touching at all from tire to control arm.
Here is my 2020 1500 4x4 Duramax. I have 2” Rough Country top coil spacer and 2”block on the rear with shock extension I put 35/12.50R20. I trimmed very minimal on the inner portion of the mud flap. Other then that i like the way it sits.
