Abstract
A trailer hitch system for equalizing trailer loads and reducing trailer sway. The trailer hitch system may include spring bars that may be attached to a hitch head using a trunnion style connection. 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. The brackets may have a contact surface on the lateral extending portion that may be free from a coating such that a metal on metal contact is made between the spring bars and the brackets. Portions of the brackets beyond the contact surface may be covered with a protective coating.
