Reese Sway Control Bar

Finishing up the first season with our TT and decided to get a friction sway control bar for our next trip. We have the Reese style hitch head with trunion style springbars. The hitch head already had the little sway control ball installed as well as on the TT. My question is about dialing in the amount of friction. How much friction should there be? Out of the box, it's tightened enough to where I can't slide the bar in or out at all. If I loosen the "On Off" lever, pull the bar out and tighten the lever back, if I put all my weight on it, it will barely slide back in. We towed the TT about 1,000 miles this year without much sway at all. Just wanted to add the swaybar for additional safety. Any suggestions would be greatly appreciated!

Thanks in advance!

You probably already know this, but proper loading of the trailer is also important to minimize sway. Adequate tongue weight, plus make sure there is more weight in front of the trailer's wheels than behind them.

I have towed over a hundred thousand miles (!) with just a sway bar -- works great on a smaller trailer like mine. For a big trailer, a weight distribution hitch works better, or so they say.

Thanks for all the great advice! I just got back today and the swaybar worked great to stabilize the trailer. I backed off the adjustment nut a quarter turn from where it was set from the factory and used the "on/off" handle as directed in the instructions by tightening it down but leaving it parallel to the bar. No sway at all at any speed. I'm sure it helped that it was pretty stable to begin with, but there would be noticable sway in high winds and when passing semi trucks. No issues any more with that.

Correct, but the steering wheel test is highly variable depending on trailer length, truck size, etc. What I do is find a straight road without traffic and do a quick input on the steering wheel to get the trailer to swing out a bit while watching for excess over-travel, then tighten the bolt a bit and retest. There will always be some over-travel due to play in the suspension and tires.

Since there is both a bolt and a handle, that is way too much for some to comprehend. The handle only needs to be tightened enough so that it doesn't move, that could be done with one finger. I doubt that there are many that are adjusted and used correctly.

Lynnmor is correct.
Here are the installation instructions from the DrawTite hitch manufacturer. The other manufacturers have the same instructions.
Sway bar installation install and adjustment.

Notice that statement 3 in the beginning states:
"3. The handle (5) is an on/off device. The bolt (7) below is for adjustment only."


Notice that in the "Hook Up" section "b" it states:
b. "Retighten handle until it stops (handle should be in its original level position)."
This means tighten the handle all the way and then back it off to a position parallel to the trailers A frame.

Then is section 3 "Adjustment" it states:
"To get maximum benefits from the sway control assembly, a series of road tests should be taken with
the loaded trailer. On subsequent trips increase or decrease tension by turning the adjusting bolt (7) in 1/4 turn increments in
the direction shown on the label until the desired control is achieved. For large trailers, it may be necessary to install a second
sway control unit."

This adjustment is done by turning the small bolt located below the handle in small amounts and road testing in between adjustments. By large trailers they are talking about those longer than 26 feet according to other manufacturers instructions.

The thing to remember is that the long handle is an "On/Off" device and not an adjustment device. By doing it the proper way, you will always be able to put the same amount of sway control on and not be guessing whether you turned the handle hard enough.
Hope this helps.:)

Please post the directions you are referring too. Otherwise, I take the direction posted by others as correct.

I had two on a 26' trailer for years. Tighten it down tight and back off until the handle is parallel to the bar. If you tighten it too much during a sharp turn you will either bend the bar or break the little ball off or both. For the first few times that you use a new friction grip sway control pull out the bar after use and clean off the friction residue with course steel wool. The residue can cause it to stick and damage the bar. Always take it off before you make a sharp turn backing up. Going forward it is highly unlikely that you will ever make a sharp enough turn to damage it.

Thanks guys! The biggest thing I worry about is having it too tight and having it break the hitch head or the trailer tongue. The thing is with these things is there really isn't a whole lot of information out there about adjusting them. Watched a few YouTube videos but it sounds like it's more trial and error than anything else.

Loosen the friction sway bar so it slides easily by turning the crank handle. After installing on both little balls, tighten the handle crank as much as you can by hand. Give it an extra "umph" and that's good. The tighter it is, the better it helps control sway. But there is a point where too tight is too much, so never use a cheater bar to make it tighter. However, it is OK to use a cheater bar if you need to initially loosen it.

Once it slides easily, remove it from both little balls until needed the next trip. I used one for years and years. I had to replace it once with a new one as the old one finally froze in place and I ended up breaking the handle to when attempting to loosen it. That was after 10 years of use too.


This is totally incorrect and the reason that so many find fault with the friction bars. Read the directions.

It sounds like from your description you had it about right. Drive with it a while, if it seems like you need a little more, tighten the bolt on the back a little. If it seems to much, loosen the bolt on the back. Over tightening it will break the balls off.

If you have the trunion style bars, add the dual cam kit to it.
Works far better than simple friction.

Too tight will pop the ball off. Check online sites for proper use. YouTube or etrailer etc
