Ultra-Fab Products Weight Distribution - UF35-946204

Attach this sway-control device to your weight-distribution system or ball mount to help prevent trailer sway. Friction-style control provides resistance to correct sway and keep your trailer in line.


  • Reduces trailer sway caused by winds, curving roads or sudden maneuvers
  • Lets you adjust tension for the perfect amount of control and resistance
    • Tension-adjustment screw easily turns in 1/4" increments to fine-tune tension
    • Built-in lever lets you disengage system to completely release tension
  • Works with either weight-distribution systems or ball mounts that have sway-control platforms
    • Does not work with surge-type couplers
  • Installs and removes quickly and easily
    • Attaches to either side of trailer tongue
    • Removes with just 2 clips
  • Includes ball-and-plate assembly, sway-control ball, and necessary fasteners and hardware
    • Sway control tab sold separately
  • Constructed of powder coated steel for durability and corrosion resistance
  • 3-Year warranty

Note: It is recommended that you remove the friction-style sway control before backing up to ease reversing and prevent damage to your system. When towing during slippery conditions such as wet, icy or snow-covered roads or on loose gravel, turn on/off handle counterclockwise until all tension is removed from unit. Failure to do so could prevent tow vehicle and trailer from turning properly.

Friction-style sway-control devices are designed to reduce trailer sway after it has already begun. As soon as your trailer begins to move out of line, the friction pads inside the unit touch one another and create just enough resistance to prevent any further side-to-side movement. To install this system, simply bolt the sway-control plate to the frame of your trailer and attach the other end to the included ball, which mounts on the head of your weight-distribution hitch or to the sway-control tab on your ball mount.

Installation was a snap! the hardest part was welding the adapter plate to the receiver! It works perfectly! No more trailer jumping around and sway all over the place! Thank you. This is a must have for your trailer if you do a lot of hauling! 50577

Expert Answers about Ultra-Fab Friction Sway Control for Weight Distribution Systems - UF35-946204Do you have a question about this Weight Distribution?

  • Trailer Ball Height to Increase Tongue Weight to Help with Sway Control on a Single Axle Fish House
  • You should have the hitch ball height set so that the trailer tows as level as possible behind your pickup. If there is a setting that goes between slightly higher than level and slightly lower than level, opt for the slightly lower setting, when the trailer is sitting on the trailer ball. An increase in tongue weight will most likely help with your sway situation. Adding weight in front of the trailer axles would be the best way to increase the tongue weight, just make sure you stay...

  • Is the Weld on Anti-Sway Ball Mount Tab Included with the Ultra-Fab Friction Sway Control Kit
  • Yes, I spoke with my contact at Ultra-Fab and he confirmed that the weld on sway control ball mount tab is included with the Ultra-Fab Friction Sway Control Kit, # UF35-946204. We also carry weld on sway control tabs separately, part # 3442, see link.

  • Can Friction Bar Sway Control be Used with a Valley Weight Distribution System
  • Friction sway bars like # UF35-946204 work independently of a weight distribution system. With that said as long as your Valley system has a small hole on the head for the small ball then you can use this sway bar. The sway bar type sway control are generally not restricted to any one system as long as that system is set up to accept the small ball. I included a picture pointing out the small hole on a head.

  • Comparing Bar-Style Friction Sway Control
  • The Curt friction sway control bar # 17200 is made overseas in China. It is comparable to the Pro Series system # 83660 and Ultra-Fab system # UF35-946204. The Reese system # RP26660 has higher quality materials inside and out and resists corrosion better so it is a better system. And it is made in the USA. But they all work in the same way. I have linked a video showing installation of the Pro Series system for you.

  • Trailer Hitch for a 2003 Chevy S-10
  • Since there are no adapters to go from a bumper mount ball you will need to install a frame mounted trailer hitch on your 2003 Chevy S-10 to be able to tow your trailer level. There are different configurations of the 2003 S-10 so I have linked the hitch main page. You will need to choose your vehicle style using the drop down menu at the top of the list on that page. Then you can choose a ball mount with the proper rise or drop needed to tow the trailer level. I have included a link...

  • Procedure for Adjusting Friction Sway Control Unit
  • Trailer configurations and loading, road and weather conditions, towing speed, tire condition and pressure, and center of gravity of trailer all affect towing and the degree of sway experienced. To get maximum benefits from the sway control, a series of road tests should be taken with the loaded trailer. On subsequent trips increase or decrease tension by turning the adjusting bolt in 1/4 turn increments in the direction shown on the label. It's very important that the tension be removed...
