Hi KNDB welcome to the forum. You'll get various responses to your question here with some saying no sway control and some saying yes to sway control. By and large though the majority will say yes to sway control even with the Anti sway feature of the Ford. The theory is that the add on sway control dampens and stops sway before it happens. While the Ford system only comes into play after the sway has started. My personal opinion it add the sway control. If for some unfortunate reason you wind up with sway; then the Ford system will hopefully come into play and stop it.
