We make purchasing extension springs easy! Here at American Garage Door Supply Inc we strive to make your purchasing process simple and worry free.

What to Know about Extension Springs

  • The common sizes today are different than common sizes of the past
  • Color coding is the consistent measure for extension springs (a 150lb red spring for a 7' door could have been manufactured in several different sizes)
  • If you are not sure what color your old spring was, use a bathroom scale to weigh the door while it is unsprung and disconnected from your door opener.
  • The weight listed for each spring is for a pair of springs (1 spring rated for 150lbs will only lift 75lbs
  • 7' doors require a 25" long spring that stretches up to 42" (67" total length when the door is closed)
  • 8' doors require a 27" spring that stretches up to 48" (75" total length when to door is closed)
  • Extension Springs are a NON Returnable item Call Customer Service if you have any questions

Starting with our easy to use selection tool, you can easily find the garage door extension springs you are looking for the 1st time!

If you are having problems please consult our Extension Spring ID Chart
