Abstract
An accessory for trailer hitch systems having components for equalizing loads and reducing trailer sway. The accessory includes a jacket for attaching to a bracket that supports a load equalizing spring bar. The bracket may include a lateral extending portion for supporting the spring bar. The jacket may include a socket for receiving the lateral extending portion of the bracket, such that the jacket may be removably installed on the bracket. The jacket may include a contact surface for contacting the spring bar. The contact surface may include a different coefficient of friction or a different shape, as compared to the lateral extending portion of the bracket, such that movement of the spring bar with respect to the bracket may be altered as compared to conditions in which the spring bar is supported on the bracket without the jacket.
