What are the Different Types of Garage Door Springs?

When we come home and push the button to make our garage doors go up, there are different types of garage door springs that help them do this. These springs are like the heroes of the garage because they do a big job quietly. 

There are two main types: one called torsion springs that go across, and the other called extension springs that are on the sides. They work together to make sure the garage door opens and closes just right. There are also different kinds of springs made in special ways, like oil-tempered, galvanized, and powder-coated ones. These help the springs last longer and resist things like rust. 

In this blog, we’ll talk more about garage door spring types, what they do, and important things you should know about them.

What are the Different Types of Garage Door Springs?

Before we talk about the different kinds of garage door springs, let’s go over the basics. Garage door springs are really important because they help the door balance its weight, so it’s not too heavy to open and close. There are two main types of these springs: 

  • one is called torsion springs, 
  • and the other is called extension springs. 

They both have their own jobs in making sure the garage door works well.

Torsion Springs

Torsion springs are put on a metal rod right above the garage door opening. After setting them up, aluminum drums are placed on both ends of the rod. The number of torsion springs you need for your garage door can be between one and four, depending on the door’s size, strength, and weight (you have to figure out how to measure garage door springs).

In contrast to extension springs, each torsion spring spreads its energy evenly along the rod before it goes to the drums. This makes the cables spin at the same speed, and that’s what helps open the garage door. There are different types of torsion springs:


These are used for regular home garage doors and are put above the garage opening. There’s a metal rod in the middle that supports the springs. If your garage door is light, one standard torsion spring is usually okay; if it’s heavier, you might need two.


These springs are in the middle of the torsion rod. Different hardware is put on both ends of the rod, next to the cable drums.


Often used in big buildings, these springs go inside the rod that supports the rolling door.


This kind of spring is known as the safest. They are kept inside the rod and are secured by a winding cone at the end of each torsion rod.

Extension Springs

Extension springs work by stretching or getting longer. When the garage door is closed, the weight goes out on the horizontal track, making the stretched extension springs tight.

Normally, a garage door has two extension springs. They are put on each side of the door, running along the horizontal track. Each spring gives its own pull. If your garage door has extension springs, you can use metal pulleys to help. There are three kinds of extension springs based on their ends: 

  • double-looped ends, 
  • open-looped ends, 
  • and clipped ends.


These extension springs are easy to change because you don’t have to open the eyebolt or take apart the pulley. The downside is that if any part is damaged, you have to replace the whole spring.


These extension springs are stronger than the ones with open-looped ends. They have two coils at the end that connect to the pulley and eyebolt. Even though they’re stronger, they can be trickier to replace.


These extension springs for garage doors are the toughest among the three. The clips put less stress on the spring, making it last longer. Clipped ends extension springs are the best for garage doors that weigh 200 pounds or more. The downside is that they are the most challenging to replace.

Different Types Based on Construction

Now, let’s look more into garage door springs based on how they are made.

  • Oil-Tempered Springs: These springs are heated and covered with oil to make them stronger and prevent rust. They last a long time and can handle different weather conditions well.
  • Galvanized Springs: These springs have a layer of zinc on them to stop rust and corrosion. They are great for places with a lot of humidity or near the coast where there’s salt in the air.
  • Powder-Coated Springs: Powder-coated springs have a protective layer put on them through a special process. This not only stops corrosion but also makes them look smooth and shiny.
