I am going to deviate a tad bit here and attempt to get to the root cause of your issue.
1- you don't have a shock problem.
2- you don't have a spring problem.
3- you don't have a swaybar problem, front and most likely the rear.
So, since none of those product the gentle side to side boat feeling, something else does. That is typically the driver, the terrain, or some combination thereof if we can fully rule out that your steering is tight and we aren't fighting play in the system. So, what you need to do for us is go take it for a test drive on a nice road at speed and check a couple of things. Can you hold the steering wheel steady on a straight road without a lot of minor corrections to keep it going straight?
When you drive, are you watching the road right in front of the rig and making minor corrections to the steering wheel based on road surface imperfections? Don't guess, hold the wheel very steady and look out several Jeep lengths in front of you and ignore road surface conditions. Does that change the the rocking motion when you do it that way?
Go take a drive and report back. I strongly suspect we have a driver problem and not an equipment problem.
I always keep forgetting the human element. @DustinfromOhio please do share what you find out.
Oh jjvw likes Blaine's comment that says it's not a shock or Antirock problem.
Of course, because it is possibly realistic solution to the problem than your constant suggestion to try the RS5000X. I have had the factory swaybar and the swayloc and tried both settings on it. I know what difference the swaybar makes .. if you atleast care to try your antirock at the extreme settings one time you would know too, and you can help people better (never questioned that intent FYI).
