Yes it does it at all speeds both towing and running empty. I also have the trailair pin box and trailair center point air on the 5th wheel.
No I did not need the air assist on the dually, but wanted to try it before I messed with the springs.
Called Dale at Trailair this morning and he said to try more air in pin box, have been carring 87 lbs will bump it up next trip out.
Maybe I'm expecting too much for the ride in the dually, had 2500HD single rear wheel last truck, and got a much better ride when towing. When running empty if I wanted a better ride I just put some weight in the box. Also had Bilstein shocks and a smaller 5th wheel.
Thanks for the replies.
