What Is an Extension Spring? An extension spring is a tightly wound helical spring designed to absorb and store energy while resisting a pulling force. Unlike compression springs, extension springs operate under tension and exert force when stretched. Most extension springs feature hooks, loops, or custom end configurations that attach to components within an assembly. Extension springs are ideal for applications requiring return force, tension control, counterbalancing, or controlled movement.
