Abstract
A spring assembly includes a spring seat clamped to a leaf spring at a center portion. The spring seat includes a cutout for distributing clamping stresses in a substantially uniform manner across the leaf spring. The cutout provides a relief for a central portion of the leaf spring to uniformly distribute clamping pressures across the leaf spring. Uniformly distributing stresses across the width of the spring increases leaf spring fatigue life.
