stock rear suspension problem

[Bill A]

I just traded my '17 Raptor for a '19. 500 miles on the new one. When I back up after the truck has sat for 20 or 30 minutes the left rear body drops about 1". It feels like I backed off a ledge or 2x6.

Had it back to the dealer yesterday. Machanic can't find anything wrong. He and 2 other machanics all saw the left rear drop when I backed up. After pulling ahead it will drop a minor amount ( when backing up ) that I can't feel but the machanics all saw.

Any ideas?????

This has been discussed and is normal. Byproduct of the active shocks engaging. Nothing bad is happening that I know of.

Yes definitely the live shocks. Nothing wrong.
