Sway Control (Dual Friction)

[Hansel]

I have a Laredo 284BH that has a Reese WD set up with a single friction bar, now my issue is with the swaying of the trailer. I'm going too double check the ride height of the truck to make sure the WD hitch is properly set up, I did notice that watching a video on youtube the guy was installing Drawtite kit#7903 and I notice that the head assemble had a spot on both sides of the head for a ball that the friction bar mounts onto, does anyone use a double friction bar set up?? or is the dual cam set up the way too go???

I've searched around alittle and can't seem too locate that head that was shown in the video, I'm thinking it would be more cost effective too just add a 2 friction bar if I could find this head that has the ball mount on both sides.
