In this review of the 180lb heavy duty garage door extension springs, the bottom line is simple: these springs are aimed at homeowners who need an exact, durable replacement for residential doors up to 7 ft high. The most compelling reason to buy is the combination of professional ASTM-A228 steel and electrophoretic black coating promising corrosion resistance and a long cycle life, which makes them a practical choice for people replacing worn or broken extension springs. Installation items included mean you can start the swap immediately.
