Abstract
A trailer hitch system for equalizing trailer loads and reducing trailer sway. The trailer hitch system may include spring bars that may extend from a hitch head. The spring bars may be attached to the trailer using rigid brackets that reduce swinging of the spring bars. The rigid brackets may include an upward extending portion for attaching to the trailer tongue, and a lateral extending portion for receiving the spring bars thereupon. Pins may be utilized to secure the spring bars on the lateral extending portion of the brackets. The pins may each include a spring loaded clip that is rotatably between an unlocked position and a locked position.
