Can Friction Sway Control Be Added to a Class II 1-1/4 Inch Non-Weight Distribution Hitch

Updated 09/22/2011 | Published 09/21/2011

Question:

I am pulling a micro camper with my 11 Subaru Outback, R3.6 Limited. Camper dry wt is 1550# and max load is 2500#, using a std class II hitch not wt distribution, that I got from etrailer.com. Hitch wt capacity is 300#, and I am paying careful attention to hitch weight. We are towing well, but notice some sway over 60MPH, and some rocking depending upon pavement surface quality. I am considering adding an anti-sway friction bar to attempt to reduce rock and sway. Can I add an anti-sway bar to a non-wt distributing hitch? Will an anti-sway bar reduce my rocking, as well as my sway at higher speeds? Thanks

Proper trailer loading is your first-line defense against dangerous instability and sway. Heavy items should be placed on the floor in front of the axle. The load should be balanced side-to-side and secured to prevent shifting. Tongue weight should be about 10 to15 percent of gross trailer weight for most trailers. Too low a percentage of tongue weight can cause sway. Load the trailer heavier in front.

You can add a friction sway control like the Reese Friction Sway Control Kit, part # 83660, to a Class II non-weight distribution hitch. You will need the Reese Sway Control Bracket, part # RP26005 that mounts to your Class II 1-1/4 inch hitch and gives you an attachment point for the sway control system. I am including a link to the installation instructions on the Reese friction sway control.

The friction sway control kit does not work with surge brakes and needs to be removed when backing up the trailer. It will help with some rocking but is designed more to help with sway from winds, curving roads or sudden maneuvers. If you are getting rocking from an uneven surface it will not prevent that.

I am including a link to a FAQ page on weight distribution.
