Abstract
A suspension system allows travel of a sprung mass relative to an unsprung mass. A primary stage has a primary leaf attached between the sprung mass and the unsprung mass. An auxiliary stage has an auxiliary leaf operatively attached to either the primary stage or unsprung mass. A variable engagement bracket includes a mount point, attached to the sprung mass and defining an axis, and an offset arm extending from the mount point and rotatable about the axis. The offset arm contacts the auxiliary stage at a first point at a first travel of the suspension system and at a second point at a second travel. The first point provides or defines a maximum contact span and the second provides a minimum contact span, smaller than the maximum contact span, for the auxiliary stage.
