I have a 2006 3/4 Ton Suburban with an 8.1, 4 whl drive and Autoride. Has anyone tried to change the rear ride height ? I've heard that shortning the length of the rod that connects the axel and the lever arm to the ride sensor will reduce the ride height. Has anyone tried this ? and how did it work ? Hooking up my 31' Airstream even with a power jack is a bear because it needs to be extended all the way up for the existing ride height. I've already dropped the ball on the equilizer hitch down to the lowest level for hookup.
