Sway Control

Need to use all mounting plates when installing sway control on trailer? Have two plates, one with eight holes and the plate with the small ball having four. Can I just use the ball plate? I do have room for all plates
  • I have used only the one plate for years and never had a problem. Important to have correct amount of tongue weight.
  • Not sure about the two plates. I have only seen the larger plate with 6 (maybe 8)or so holes in it. If you have a choice, I would use the larger plate.

    There is a terrific amount of force on that small ball when the trailer tries to turn or sway and the possible slight movement may be too much for the thin steel of the trailer A frame. The "tin canning" of the metal could cause it to fail. The larger surface of the big plate will tend to counteract that.

    Edit: Watch this video. It explains what the larger plate with 8 holes is for. After watching it, I still maintain it would be best to use it for the reason I mentioned.
  • I recommend using the spacer plate. When I first started RV'ing I installed my sway bar mount incorrectly and it caused the bar to crash into itself and the ball mount on the WD hitch during tight turns.

    Well, this is what I ended up with.



    More importantly than using the plate or not Mount it correctly. This measurement needs to be exact or you can do what I did... I was about 1 inch off IIRC.

    thanks!
