In order to order new garage door torsion springs, you will need to measure (as accurately as possible) your current spring(s) and find the:

1. Wire size

2. Inside diameter (90% of doors have a 2.0" inside diameter)

3. Spring length (how long each spring is)

4. Spring orientation only worry about this if you have a 1 spring system (left wound or right wound). Generally, when looking from within the garage, if the spring is on the left side, it is right wound, and vice versa. It works as opposites, so if the spring is on the right side of the center when looking from inside your garage out to your door, it is left wound.

1. Here's How to Measure for Wire Size in < 1 minute (Step 1 of 3)

The only way to measure this accurately is to measure 10, 20, 30, and 40 coils and find a match on this chart. It is okay to round if you are very close.

Wire size is the most important measurement. This determines the strength of the spring. It is not recommended to manipulate this to try and get a longer life or stronger spring. If you'd like to upgrade your spring(s), you can add this to your cart:

2. How to Measure for Inside Diameter (Step 2 of 3)

It is very likely that, like 90% of Americans, you have a 2.00" inside diameter.

Please double check by measuring just the inside (interior) diameter of the spring. You can measure this while it's still attached.

3. How to Measure for Spring Length (Final Step)

Spring length is the most flexible measurement, but you should do your best to be within 1-2 inches.

The spring length may change slightly after years of use, weather, etc.

4. How to Determine Winding Orientation (left-wound or right-wound) *Optional

A general rule is that if the spring is marked with RED paint, then it is RIGHT wound.

Furthermore, if the spring is on the left side when looking from within the garage, it is RIGHT wound.

If you have a 2-spring system, you should replace both springs and you can skip this step.

Garage Door Nation,
Just wanted to drop a line to say "Thanks." Got the parts and my garage door is now working better than ever. Converting from a single spring to a dual spring was the key. A great product at a great price with great service! Thanks Much!!

Just wanted to thank Garage Door Nation for making this possibly the easiest DIY home repair. The kit had everything I needed. The videos were very helpful.

There is some potential risks involved with this project, but if one just follows the step-by-step instructions of the videos, they will have no problems.

I wanted to commend you for making torsion spring replacement an easy job. Anyone with a meaningful level of mechanical ability can do this; your tutorial was all it took to get the job done correctly in a little over a half hour. Nice.

Received all parts on Friday and they worked perfectly. My thanks to garagedoornation, you all provided great parts and the video by Tom Mello was spot on making the job very easy and safe. I appreciate it very much and thank you for the great support.

Just wanted to let you know how much I appreciate the quick service. Received the order and followed your excellent video on installation of the springs. I ordered a complete kit plus some extras so it took me a bit longer, but absolutely no problems with the installation and now my garage door works great. As someone who has written several assembly manuals I can say that your video instructions were way above average and easy enough for any novice to follow and succeed. Well done and thanks. I will recommend your company to everyone.
