Abstract: This invention relates to central hanger brackets and equalizers for tandem suspension, used in trucks, trailers and semi-trailers, provided with spring pack arranged on the axles of the vehicle comprising an equalizer, provided with an intermediate area located in the upper part of the body, said area coupling to a surface arranged in the central hanger bracket. The set promotes a structural arrangement that allows the articulation of said equalizer, and eliminates the use of fixing pins, bushings or screws to attach said set to said central hanger bracket, in order to simplify the system and reduce the number of components, providing better conditions for the durability and maintenance of the suspension and thus reducing the operating cost and the cost of the product itself.
