Claim:
1. An energy storing suspension component in combination with a bushing comprising: an energy storing suspension component comprising: an axle seat portion, an end configured to include an eye, and a limb extending between the axle seat portion and the end, wherein the limb comprises a first taper wherein the limb decreases in width as the limb extends toward the end, a second taper wherein the limb decreases in thickness as the limb extends toward the end, wherein along the limb there is at least a portion where both the first taper and second taper are present, and a third taper that is further from the axle seat portion than the first taper and wherein the limb increases in width as the limb extends toward the end, wherein the energy storing suspension component has a lower lateral spring rate than vertical spring rate; a bushing having a high radial to axial rate ratio; the bushing further comprising a central body and at least one rate ring portion having two or more pieces, and a continuous cylindrical outer can, with at least one first elastomeric member disposed between the central body and the at least one rate ring portion, and at least one second elastomeric member disposed between the at least one rate ring portion and the outer can; and wherein the central body, at least one first elastomeric member, at least one rate ring portion and at least one second elastomeric member have been pre-compressed and received by the continuous cylindrical outer can prior to the bushing being received by the eye of the energy storing suspension component.
