Ah I didn't realize the sway was built into the equalizer. I used to have a separate friction plate that installed between the hitch and trailer tongue in addition to the equalizer. Maybe those are old technology now.
Mile High... don't be confused between the brand named Equal-i-zer (a weight distribution unit with built in sway control) and a run of the mill weight distribution unit without built in sway control. Two different animals. The latter is typically used with a separate friction type sway control bar. This is NOT as effective as the units with built in sway control.
Many people call the weight distribution unit an equalizer unit. In a sense they do "equalize" the weight of the trailer tongue, but they are better described as "distributing" the tongue weight of the trailer to the truck's front wheels and the trailer's wheels, making the load on the truck's rear wheels less. Hence, they are normally called weight distribution units.
As for weight distribution unit that have sway control built in...there are many different brands...some much better than others. Some are friction based and others incorporate a mechanical design.
Hope this helps rather than confuse.
