The present disclosure relates to a method for producing a leaf spring 1 for a vehicle axle suspension, wherein the at least one spring arm 5 bordering on a clamping portion 2 is formed from a rod-shaped preliminary material 7, 8 by a rolling process. By the rolling process for shaping the leaf spring a preliminary material rod 7, 8 having a rounded cross-sectional geometry is rolled out to produce a rectangular cross-sectional geometry in the clamping portion 2 and in the at least one spring arm 5, and thus the portion of the preliminary material rod 7, 8 provided for forming the clamping portion 2 in the finished leaf spring 1 is also reshaped by the rolling process and as a result a rolled structure is also formed therein.

Energy storing suspension components having an end configured to include an eye are disclosed in combinations with bushings for use in suspension systems for wheeled vehicles and trailers. The energy storing suspension components include an axle seat portion, an end, and a limb extending between the axle seat portion and the end. The limb includes 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.
