Ford Anti Sway and Blue Ox Sway Control

[Amazen1955]

For me this question is decided! I’ve followed several threads that contradict each other and are quite positive in their perspective. One side says Turn off anti sway in your truck and just use what comes from the hitch. The other side says they work completely in different ways and compliment each other. Recently going to Florida thru Tennessee and Georgia it was raining (drizzle) roads were wet with a good amount of water. It was a two lane divided hiway speed limit was 65. The road got a little curvy...not twisty just curvely and rolling hills. I was running about 63 while most people were doing 70. All of a sudden the trailer started swaying not heavy but noticible. Then it gave a big sway the truck anti sway immediately kicked in stopped it and on we went a little Leary but not concerned. It showed me how the truck anti sway only kicks in when things get dicey not in keeping the trailer quiet as you go along. It solved the question for me for sure...I will have the anti sway on while driving. Il also slowed it down when it gets that little bit curvy when wet! The truck anti sway was a definite saving grace in that situation. Have a 2020 max tow F150 long bed pulling 31 ft TT weighing 6800 lbs. It made a believer out of me!

The anti-sway system on the Ford/Chevy/RAM are not pro-active systems, they are a reactive system designed to work when the sway gets to a certain point. Same idea as anti-lock brakes. One should have an anti-sway hitch to prevent any trailer sway, with the truck system activating when things go beyond what the hitch can do.



Not sure why anyone would deactivate the system, as it does nothing until you get to that certain amount of sway.

Does anyone know if these anti-sway truck systems activate just the trucks various brakes to mitigate sway or does it also activate the various trailer brakes also?

I don't know how the system works (don't own one). However, from the physics of it, truck only brakes is the WORST thing you can do when trailer sway occurs, I'm betting the system likely works with trailer brakes only.

FYI, there is an aftermarket system you can add to your trailer that does this. Not sure how well it works.

I just watched a video that stated all f series trucks will have trailer sway control and will apply the trailer brakes if the trailer is plugged into the truck.
