Over at their web site, they say that the friction of metal on metal is one
component of their sway control. 'Better than friction material'...
This friction is the resistance to the sway.
I agree, but on that surface there is no sway control. In a sway situation it would take some dramatic side to side sway at least 25 deg or more from the trailer for the sockets at the hitch head to stop any type of sway! I know they say "4 point sway control" but seeing how little those bars move in a slight turn it will not stop sway. The only real sway control is at the L brackets!
