Garage Door Torsion Spring Q&A

What size torsion springs do I need for my garage door?

Standard residential garage door torsion springs are found on a shaft above the center of the garage door, or there could be at the rear end of the horizontal tracks if you have low head room garage door system (Photo Below). The Springs typically come in 1 ¾, 2” and 2 ¼’ inside diameter.

How long does a garage door spring last

The answer to the question is depending on a number of things. The majority of modern overhead garage doors use a torsion spring, which has a standard rating of approximately 10,000 cycles. Each time you open and close your garage door, you complete one of these cycles. If you typically complete around 3 to 7 cycles each day, your garage door spring’s life cycle would be around 3 to 10 years. 

However, other factors — such as increased cycles, temperature changes, and lack of regular maintenance — can negatively impact how long your garage door springs last. Once you reach the end of your garage door spring’s life, you need to replace it. Depending on how often you use your door, you may want to consider high cycle springs. These springs, also known as long life garage door springs, are ideal if you complete over three cycles in a day. 

Can I use garage door spring 2 inch instead of 1 3/4 inch inner diameter?

If you currently have 1 3/4" ID or 2" ID springs, there is nothing to gain by changing the inside diameter from one to the other. The springs have the same lift or torque rating, and they have the same cycle life.

There are a few situations where it is advisable to convert from one inside diameter to another.

One is when the springs are very old, and the hardware or cones are obsolete.

Another situation is where you may want to install high life springs, but there is not enough room on the shaft. Increasing the inside diameter will allow you to install shorter springs with the same longer cycle life.

A third application would include times when springs with different inside diameters are available, and you need to check to see if what's available will work. For example, many doors have 1 3/4" ID springs, but some door companies carry only 2" ID springs on their trucks. This converter will provide the length of a 2" ID spring you will need to install if the broken spring you are replacing has a 1 3/4" inside diameter.
