How It Works
Downward pressure from the trailer tongue and upward pressure on the spring arms activates the rotational friction sway control. The spring arms link the rotational sway control to the sway control brackets and distribute the weight of the trailer tongue. The rigidity of the sway control brackets allows the dual rotational friction sway control to hold the trailer in line behind the tow vehicle.
Spring arm size 1" sq. x 36"L
