The chstThis high cycle garage door torsion spring conversion chart color coded is what I use to make sure I’m always putting the right spring on a garage door.
If your springs didn’t last as long you thought they should then this article is for you. I will explain what makes some springs last longer than other and how to get springs that will last much longer so you don’t have to replace them ever couple years.
Most new sectional garage doors come with 10,000 cycle springs from the manufacturer. These springs usually last 6-8 years under normal use. brantdavidson.com
But many households use their garage door as the main entrance to the house and may open their garage door 15 – 20 times a day. When a door is used that much the spring life may be shortened dramatically. In those cases it is not unusual for the springs to last only a couple of years. If your springs break often you may want to upgrade to a higher cycle.
The springs life is based on rotations. Each time you open and then close the door you have just used one cycle. A standard 10,000 cycle spring will open and close the door about 10,000 times before it is worn out.
So if you park 2 cars in the garage and you open and close the door one time for each car to leave in the morning and one time for each car when you come home at night that would account for 4 rotations per day. Assuming you don’t go to the store and never open your door any more than that, your standard spring would reach 10,000 cycles in a little less than 7 years.

A house where the garage door is used as the main entrance and gets opened 15 times a day would use 5475 cycles per year and in that case would only last about 2 years. If you fall into this category then this article was written for you.
I carry only 18,000 cycle springs on my truck. I charge $195.00 to replace both springs on a standard size 16’x7′ metal 2 car garage door, total cost, out the door. That’s my everyday charge for customers in my service area, Riverside/Corona CA and the surrounding areas. Assuming that your old spring was the original 10,000 cycle spring, you can expect my 18,000 cycle to last nearly twice and long. brantdavidson.com
If that is still not enough rotations we can upgrade to even higher cycles. The chart below is what I use to figure out what spring is right for you. These higher cycle springs are special order and would require 2 trips out to your house and a trip to my supplier.
The first trip out I would measure your old springs and calculate the new size for the higher cycle, then come came back to change it either later that day or sometimes the next day, but I usually do it all the same day.

I charge a little more to cover the extra trip to your house, and the added cost of the larger spring (very reasonable). For the higher cycle I might recommend something around 50,000 cycles that would last 5 times longer than the original spring, under the same use. brantdavidson.com
Whether you get the 18,000 cycle spring that I normally carry, or you pay more for the special order higher cycle, the warranty is the same; 1 Year parts and labor. But that is a real warranty. It covers 100% of the cost to replace the springs.
I do not charge any service charges to you for a warranty call unless there are problems with the door that are not related to the spring, for example an opener repair would not be covered under the spring warranty.
I would be wary of any company offering a lifetime warranty on springs. If they do they will usually only cover the spring and they will charge you a hefty labor charge. Some companies charge more labor on a warranty call that I charge for the whole new spring change. brantdavidson.com
You can see by the charts below that when it comes to garage door torsion springs, usage and spring size determines longevity.
How to use this chart
The 2 charts are basically the same but one is for 1¾” ID and the other is 2″ ID. Which chart you use depends on the size of the spring you are replacing. I usually use the 1¾” ID because that’s what I carry. They are a little easier to change than the 2″ ID.
The left column shows the weight that each spring pulls individually. Two 80 pound springs is the most common size I see for metal roll up doors. For wood doors, two 150 pound springs is most common.
The top row of the chart shows the # of rotations x 1000. The spring I use most often is the 207×25. 207 is the thickness of the springs wire and 25 is the length of the springs coil in inches not counting the end cones. Each 207 x 25″ spring pulls 80 pounds at 7 winds and is rated for 18,000 cycles. brantdavidson.com

The color code of each measurement on the chart coincides with the color that the springs are usually marked with from the manufacturer. These colors are industry wide and usually, though not always, accurate.
This chart is only accurate for standard 7′ high doors. For taller doors you can adjust by percentage.
