What Is a Garage Door Extension Spring?

If you’ve ever needed a garage door repair, you’ve probably realized that your garage door and opener are much more complex than you originally thought. Your garage door and opener are comprised of many components, including:

  • Track and roller
  • Springs
  • Garage door lock
  • Opener chain
  • Opener travel
  • Eye beam
  • And more

When it comes to your garage door springs, you likely have one of two types: an extension spring or a torsion spring. For this blog post, we’ll focus on the extension spring.

Garage Door Extension Springs

Garage door extension springs are a type of spring used on lighter, single garage doors. The purpose of a garage door extension spring is to counterbalance the weight of your garage door when it opens and closes. Specifically, a garage door extension spring does this by extending—or stretching—then contracting to counterbalance the weight of the door when it opens and closes.

If you’re trying to locate your garage door extension spring, you’ll find one (usually) on each side of your garage door above the tracks.

However, for heavier garage doors or for commercial garage doors, it’s possible that you have more than one garage door extension spring on each side.

The type of garage door you have will largely determine what type of extension springs you need. For example, one-piece garage doors and sectional garage doors require different types of extension springs.

In addition, your garage door height will determine what size garage door extension spring you need. Installing an the incorrect sized extension spring can lead to premature spring failure and ultimately the need for garage door repair. That’s why it’s best to let a professional install and repair your garage door extension springs for you.
