Sway control bar >>>

Kenny, don't let people convince you that sway control is just a gimmick. No, it shouldn't sway at all under ideal conditions. Windy areas and large vehicles will push any of them. That sudden gust of wind that comes from nowhere; that stretch of asphalt with a rut in the middle of can cause problems. Just make sure it tracks straight on good roads in calm wind then add your sway control. Cheap insurance to keep it handling well. Don't let pride talk you out of it.

My two cents. My sig has my stats on it. Mine came with one and ended up buying two, so much more stable when trucks and large vehicles pass. I believe the cost was $80? Well worth it. Trailer is about 6,500 pounds behind a half ton.

I assume you have some sort of weight distribution set up...if yes, many can be converted to a Reese Dual Cam system that has built in sway control and will work much better than either a single or double anti-sway friction bar. The cost is a little more, but you will get much better performance.

Good luck and hope this helps

Before you buy special equipment searching for a solution ,
make sure you have enough tongue weight .
The design of certain trailers and the placement of the axles on the frame of such trailers can be the culprit.

There are ways to mod a TT to cure this, adjustments can be made and might be, money well spent . The most common reason for sway is not a lack of a sway control bar . Least expensive way is , move items in the TT forward to transfer weight. Try that , then road test it .

Adding sway control is helping but not attacking the core of the problem, its just masking it. A strong enough crosswind or bow wind from a passing truck can overcome sway bars if you have not addressed the core problem. Don't be fooled by a false sense of security because you added a sway bar and it feels better in a moderate wind.

Other factors involve the tow vehicles wheelbase, overhang distance from the tv rear axle to the ball .

You may have something causing sway. Post actual weights and pictures of hitch setup for useful advice. As far as sway bars go, when I needed one, two was not enough.

Buy one and then if necessary buy the second.
