I have wanted to add an anti sway device but couldn't find anything for a straight tongue trailer that many of us have. I decided to make my own. I have a 7x31 Legend Trailer. It pulls really nice up to about a 18-20mph wind, then I can tell its back there. I am pulling it with a 2019 F250 gas. All of the reviews for these simple sway control units are very good so I thought I would give it a shot.
The total cost of the steel and 2 Kurt's Friction control units was about $130 (cheap!!!). The plates that mount to the trailer are 6x6 and 1/4 inch steel (trailer tongue is 6 inches long by 3 wide). The tubing is 2x2 by 1/4 inch. The longest part of the tubing is 12 inches. I used 1/2 bolts to mount the plates to the trailer and 3/8 for the sway control ball plate. The kit comes with self tapping screws but I used bolts instead. It clears the jack no problem so I probably would have been fine at 10-11 inches. I still have plenty of clearance for the door as well. I drilled all my holes before welding things together.
They recommend one anti sway on each side if you are over 6,000 lbs and 26 feet. I am right at 6,000 lbs and 31ft. If I was going to do just one, 4 or 5 inches from the trailer frame would be plenty. The distance from both balls on the anti sway should be 24 inches. I ended up at 25 inches because of where the jack sits. I did a few tight turn and everything seems ok.
I haven't got it on the road yet so no reviews there, but overall happy with the way it turned out.
