Abstract
A vehicle suspension having a frame attachment portion attached to a saddle, first and second bolster springs mounted to spring mounts on an outboard side of the saddle and mounted on walls of a spring mount on an outboard side of an equalizing beam, and third and fourth bolster springs mounted to walls of a spring mount on an inboard side of the saddle and mounted to spring mounts on an inboard side of the equalizing beam, wherein upwardly extending flanges on the bottom of the first and second bolster sprints are mounted to each other using a common fastener, and wherein upwardly extending flanges on the bottom of the third and fourth bolster springs are mounted to each other with a common fastener.
