ABSTRACT:
An equalizer for a suspension system for a trailer is configured to absorb or dampen the harsh shocks or vibrations coming off of the leaf springs proximate to a center frame hangar, thus allowing for a “softer” ride. The equalizer utilizes one or two independent equalizer arm assemblies or castings which are each rotatably secured within the equalizer. Each equalizer arm assembly or casting is operatively associated with one of the leaf springs such that upon upward movement of the leaf spring, the associated equalizer arm assembly or casting is forced to rotate within the equalizer and to deform a shock absorber provided within the equalizer. The shock absorber, upon the deformation thereof, absorbs the harsh shocks or vibrations which would otherwise normally be transferred from the leaf springs, to the equalizer, and thus to the frame of the trailer.
