I installed on my E450 class c on the front and removed them after a couple of trips and sent them back. It seemed like the steering got to be really jittery. I would hit a bump and the thing would just jump one direction or another. Very disconcerting. I had already installed Firestone helpers in place of the bump stops on the rear and helped a lot so I was figuring the fronts would help too. It seemed to me with the twin I beam front when one side gets unloaded from a bump then retouches the Sumo Spring it would kinda pull at the steering wheel unexpectedly. Just my thoughts.
