2nd dam

I believe should be able to push the bumper up a bit to close off that gap. Looking at other rams I think mine is a bit lower than what it should be. I had the bumper of years back for a tow hook install.

so you think the 2nd air dam is a waste? I also looked at the possibility of the smaller deflectors off the frame and that should be do-able...
If you had the front airdam done,and the rocker panel bottoms matched that of the airdam,you'd be dragging an inverted pool of dead air around under the truck,with energetic flow down beneath it.
The 2nd dam would be entrained within the dead air mass and not really in a position to to affect the flow.In a crosswind,the air would 'see' the outside edges of the second dam,and unless it had generous outer edge radii,it could trigger flow separation which otherwise would not exist,aggravating the wake.
If it were me,I'd be looking at a belly pan.Trucks have the worst under bodies and respond the best to paneling.
