How are people setting their WDH bars with air springs? On the 4-corner air suspension, FCA recommends putting it jack mode, measuring fender heights, adding the hitch, then adjusting the bars so the front returns 2/3rds of the distance back to level. It has the advantage of being able to lower the front in addition to raising the rear. The airbags otherwise just raise the rear, leaving the front raised. above level.
