2 sway bars on a pull behind trailer

I've got a 32 foot trailer and I get real tired every time a bigger vehicle passes me my trailer sways back and forth.

Just wondering, other than price to buy it, is there anything negative about putting 2 sway bars on my hitch? One on each side.

  • I think there are some instructions that specify two for trailers over 24 or 26 ft. Same general idea.

    You are right about tractor trailers. Those things didn’t bother me. Small SUV’s and minivans have some funky air pressure waves when they pass ya.

    Thanks!

  • Actually 2 sway bars are recommended for a TT over 30'. however. I would do as suggested, and readjust your hitch, and TT balance. I tow a 30' TT with my 150. I have no sway, and the big trucks don't bother me a bit. Strange thing is. I can feel regular vans, and trucks pass. But not the 18 wheelers
  • Never had a problem pulling my Jayco 33RLDS that was 35.6 feet long with a Ford Excursion with 1 sway bar. If being passed by 18 wheelers the truck and trailer maybe might move 1/4 inch. but no sway.
  • Howdy. Not certain what you're towing or what you're towing with. If the trailer box is 32 feet plus the hitch, you're about 35 feet in length--pretty fair sized trailer. Now if the tow vehicle is a 1/2 ton, with 1/2 ton tires and suspension, this might be a large part of the problem. One can imagine you're looking like a set of doubles in a wind storm.
    We 're running a 30 foot hitch to bumper trailer towed by a 3/4 ton Ram 6.4. Trailer weighs between 6700 and 10,000 (empty, loaded), has 10 ply tires and a Equalizer hitch. Truck weighs about 7500 lbs. and has 10 ply tires. NO SWAY.
    Now, if all is good with your rig, check the hitch setup and weight distribution bars for proper adjustment. You might be light on the front tires, tire pressures need adjusting, etc.
    This is a good place for questions, keep coming back.
  • You would be better off making some adjustments to try and reduce the effect. More spring rate or more weight at front of trailer.
    Also, a better hitch like the Reese Dual Cam with active sway control will both resist sway and push the combination back in line.
    There are other brands that offer active sway control but I've not used them.
  • Nope...works great. I ran two with my TT.

    You can pick one up at Harbor Freight for a few bucks.
