With their tight-coil design, extension springs are engineered to absorb and store energy while generating resistance to a pulling force. Common extension spring applications include: automotive uses, garage doors, trampolines, and machinery. Utility extension springs are ideal for use with OEM or maintenance and repair applications. All springs meet ASTM standards. Please consider the rate per inch and max load-in when choosing a spring. Rate per Inch: the amount of weight a spring will withstand per utilized inch. Max load: the maximum load a spring should withhold in total.
