I would experiment with different air pressures in the Air Lift # AL57577 that you have installed in your 2020 Ford F-450 to see if you can find a pressure that reduces the harshness. I would try first lowering the air pressure by a significant amount as typically too much pressure in the bags will create a harsh ride quality. Contrary to what the name implies the air bag suspension kits aren't designed or known to make the ride quality smoother. Their primary job is to provide more suspension support which will easily make the ride quality harsh. Trick is to find just the right amount of support to reduce any sagging but not so much that the suspension gets too unforgiving.
