2018 standard cab swb, 2wd, 13,000 miles. The original 17" wheels have been replaced with 20's by PO. It might have a leveling kit in the front because it it sits pretty level.
I've searched the net and found that many 4wd silverado owners have changed to Bilstein shocks to fix similar problems. The only two options I can think of are to change back to 17's and try the Bilstein shocks. Both cost money so I'd like to be reasonably certain I'll get some improvement before throwing money at it. Any suggestions will be appreciated.

Post an image of the truck so we can get a better visual.

Since you mentioned it's 'leveled', it has me questioning what was used to complete the change?
Obviously, the change from 17" to 20" tires will have some impact on the ride (depending on sidewall heights) so that plays into things as well.
