Certainly appreciate everyone posting information here with pictures. Helped a lot. I finally got my lift and wheels on this weekend. 2021 Silverado Custom. Added a 4" rough country lift front and back. Fuel hostage D625 rims are 20x9 +1. Terra Grappler tires are 295/65 R20.
I don't feel there is a difference between stock and modified ride. Rides and handles great.
Required some trimming to the fender liners but not bad.
