Installation Notes

Extension springs store energy under tension and should be handled with appropriate care to prevent snapping during installation or removal. Relieve all load from the existing spring before removal and ensure the replacement spring is fully seated in its mounting hooks or anchor points before applying tension. Standard hand tools are sufficient for most installations. Follow applicable safety practices when working with loaded spring assemblies.
