Leaf springs remain one of the most reliable and widely used suspension components in commercial vehicles, trailers, buses, and off-highway equipment. Their durability directly influences vehicle safety, payload capacity, ride stability, and overall operating costs. While operating conditions and maintenance play a role, leaf spring durability is primarily determined at the design stage. Subtle choices in geometry, material selection, stress distribution, and manufacturing processes can significantly impact service life.
