ABSTRACT:
A leaf spring for use in a suspension system is disclosed which includes an eye for attachment with the frame member on one side of a vehicle chassis. A front cantilever portion of the leaf spring extends from the eye to a predetermined point of the leaf spring. A rear cantilever portion extends from the predetermined point to its own endpoint which is positioned in close proximity to the end of the leaf spring. The front cantilever portion of the leaf spring has a relatively high spring rate and the rear cantilever portion has a relatively low spring rate to provide comfortable riding conditions for the vehicle and roll stability for the suspension system while eliminating the practical necessity of implementing auxiliary roll stabilizers within the suspension system.
