When searching for an extension spring it is most important to determine what information you have about the spring or the application. Most of our customers fall within the following 3 categories.
- You have an existing spring in hand and are looking to duplicate or replace the spring
- You have an existing spring, but are looking to modify this spring to fit better in your application
- You are starting a new project and are looking to find an extension spring for your new application.
First let’s make sure what you are looking for is classified in the industry as an extension spring. To the left you can see an example of how an extension spring will work and to the right a blueprint showing the dimensions of an extension spring.
Now that we have determined you are searching for an extension spring and what type of customer you are, let us start our search.
Category 1
For all customers in category 1, replacing an existing spring, here is how you search for an extension spring.
Step 1: Measure your extension spring. For most accurate measurements we recommend using a dial or digital caliper. If you do not have a caliper to use we recommend using a tape measure or ruler. The main dimensions you want to measure for a basic search are outside diameter and length inside hook. The measurements you will use to narrow down your search are wire diameter, wire type and load.
Step 2: Use the search extension spring tool, modeled to the right. We recommend starting with a wide search and narrowing the results down. We would suggest starting with the outside diameter and length-inside-hook of the spring. If your spring fits inside or over other components in your application please make sure to take that into consideration. Please also take into consideration the tolerances on your dimensions.

Category 2
For all customers in category 2, modifying an existing spring, here is how you search for an extension spring.
Step 1: You will still need to measure your existing spring using calipers or other measuring equipment.
Step 2: Enter the dimensions of your extension spring into our Spring Creator Calculator. Make sure you are on the extension spring module by clicking “extension” at the top. The calculator will determine the “rate” of your existing spring. From there you will need to manipulate the extension spring to increase or decrease the strength.

Step 3: When you have determined the new rate range for your replacement extension spring enter the dimensions into the extension spring search tool.
Category 3
For all customers in category 3, starting a new project, here is how you search for an extension spring
Step 1: Determine the space, width and height, the spring will need to fit into. Use these search criteria to narrow down your search.
Step 2: If you know the force profile required in your application, use the “rate” search criteria to narrow down your search. Please note, rate is the amount of force per inch of distance traveled.
Step 3: If you are starting a new design we recommend choosing a few springs within your search criteria that fit in your application. By choosing different springs with unique force profiles it will allow you to determine which spring works best for your application. At this point you will be prototyping your application to determine which extension spring works best.
Step 4: Once you have received the spring options, test them in your application to determine the extension spring that best fits your needs. You can return to our stock store to purchase higher quantities of the extension spring or email us at sales@thespringstore.com to let us know of any additional modifications you need.
