Our take on the 80 lb. Garage Door Extension Spring- 8' Door

This is a single extension spring for an 8-foot-high sectional garage door, rated at 80 lb of pull. It uses gold Dasma color coding, high-quality spring wire, double-looped ends, and a 0.946 in inside diameter, and it stretches from 27 to 48 inches. It is rated for a minimum of 10,000 cycles, which is a standard service life for a residential spring rather than a premium one. It suits a do-it-yourselfer replacing a matched pair on a standard 8-foot door; buy two, since doors run on balanced pairs.

Pros
  • Clear 80 lb rating and gold Dasma color code for matching
  • Double-looped ends for secure attachment
  • Rated for at least 10,000 cycles
  • Stretch range of 27 to 48 inches covers typical 8 ft door travel
  • Standard 0.946 in inside diameter fits common hardware
Cons
  • Sold as a single spring, so a pair is needed for a balanced door
  • 10,000 cycles is a baseline rating, not an extended-life one
  • Extension springs store heavy tension and are risky to install without safety cables
  • No safety cables or hardware included

Questions and answers

How many springs do I need for my door?
Garage doors use springs in pairs, one per side, so a standard replacement takes two. Replacing only one leaves the door unbalanced.
What does the gold color code mean?
Gold is the Dasma color code for an 80 lb spring. Match the code and the door height so the new spring balances the door the same way as the old one.
Will this fit an 8-foot-high door?
Yes, it is made for 8 ft high doors, with a 27 to 48 inch stretch and a 0.946 in inside diameter. Check your door height and existing spring size before ordering.
How long should the spring last?
It is rated for a minimum of 10,000 cycles, roughly several years of normal daily opening and closing. Heavy use shortens that.
Do I need safety cables?
Yes. Extension springs should always be run through safety cables so a broken spring cannot fly loose. Cables are not included with the spring.

At Home Depot, for $14.16, 25% under what the other stores charge, as of our latest check.
