Examples provide a trailer hitch system for connecting a tow vehicle and a trailer. Some examples of the system include a vehicle connector configured to be coupled to the tow vehicle and a chamber coupled to the vehicle connector. The chamber includes a center, an interior wall, and a valve for modulating a flow of hydraulic fluid within the chamber. A pin extends through the chamber and is configured to rotate within the chamber. A paddle is coupled to the pin and sized and shaped to sit substantially flush against the interior wall. The paddle is configured to push the hydraulic fluid in a first direction and a second direction through the valve. A trailer connector is coupled to the pin and configured to be coupled to the trailer.
