Product Description

Now you can replace your own garage door springs thanks to this handy replacement kit from North Shore Commercial Door. Each garage door torsion spring replacement kit includes replacement torsion springs and sturdy winding bars to help you make the switch quickly and safely.

Standard springs come with a life of approximately 10,000 cycles. With our long-life option, you’ll get about 25,000 cycles out of your garage door torsion springs for just $15 more. Please note: when long-life spring option is picked, the spring size shipped with be different from what you ordered. We will have calculated the change in size to provide a spring that will function the exact same but will last much longer than your standard life cycle springs. For additional information about our garage door torsion spring replacement kit, see our “Questions” app below.

We always recommend replacing your garage door springs in pairs on doors with 2 springs. Springs are designed to open and close the door a predetermined number of times - if one spring breaks, it's only a matter of time before the other spring does, too.

  • Includes spring and winding bars for easy replacement
  • Comes with cones attached on each end as shown
  • Available in wire sizes and inside diameter sizes to the nearest 1/16th inch
  • Order custom spring sizes to fit your doors
  • Choose from left- or right-wound springs

    The four items required to purchase the correct replacement torsion spring:

    #1 Wire Size
    #2 Inside Diameter
    #3 Length of spring
    #4 Wind of spring (Right or left wound)


    A spring’s wire size can be determined by several different tools or techniques. Use of a caliper, micrometer, or wire gauge are common ways to determine a spring’s wire size. If none of these tools are available, simply measure ten coils of wire to the nearest 1/16th of an inch, and refer to the Spring Wire Chart. The spring must be tightly compressed, with no gaps. It’s also a good idea to measure twenty coils as a double check.


    Measure the inside diameter to the nearest 1/16th of an inch. In most cases, the cones inserted in each end of the spring will have a manufacturers name (OHD or Raynor, etc.) which will give a clue toward the proper identity. The chart on the right shows common ID’s used by various manufacturers. If no manufacturers name is evident, usually a part number on the cone will indicate the inside diameter: 134 or 175 = 1 3/4" ID 258 or 263 = 2 5/8" ID 375 or 334 = 3 3/4" ID


    Measure spring length with the spring in its unwound state. In the case of a distorted or broken spring, simply count the total number of coils and multiply by the wire size. 120 coils x .250 wire = 30" 120 coils x .375 wire = 45"


    To ensure the correct wind, please refer to the Winding Chart below. Please remember the side of the door a spring is located on does not indicate the wind of the spring. Most winding cones are color coded for hand identification. Right hand wound springs should have red winding cones. Left hand wound springs should have black winding cones.

    COMMENT: I took the measurements as directed and added high duty because I don't want to ever do this again! by Steve M 3/25/2015

    QUESTION: How do you determine what size spring you need for a double door? by None N 10/25/2014
    ANSWER: Do you have your existing broken spring? <br /><br />If so,take the broken part and measure 20 coils. Divide that amount by 20 so, if you measured 5" divided by 20 you get .250Do not round - they usually go by 1/8 incrememnts. This is your wire diameter.<br /><br />Next you need the inside wire diameter - this is written on the cone of the spring. If you see P200 that means you have a 2" inside diameter. On some it may actually provide you with the OMI measurement instead of the P#.<br /><br />Next measure the length of spring. Spring must be unwound and take a measurement. you can be within 3/4" Do not add the cone.<br /><br />Finally, determine if you need a left or right hand wind. If ou see the wire coming over the TOP of the cone on the right it is a right wind. If it is going of ther TOP of the left it is left wind if it is still on your garage, the left side is your right hand wind and if it on the right side it is a left wind.<br /><br />If you are not comfortable with taking these measurements you can call a local garage door company and give them the length/height/weight of your garage door and they can also tell you what will fit. by Steven M a
    ANSWER: I was able to calculate with an on-line calculator. You'll need to weigh your door. I just used my bathroom scale. Then while opening the door by hand, count the number of turns the pulley wheels make. With that info you can calculate the right springs. by Erik G a
    STAFF ANSWER: You will need to measure the existing Springso by Matthew O a
    QUESTION: I have installed the springs but cannot get the right amount of tension. Currently I have about 7 winds on the spring. The door will not stay down on it's own and flies up too fast. Then, it will not stay in the open position. What might be wrong? The new springs are longer than the old ones but I believe that was expected. Otherwise they appear to be correct. by Craig R 7/22/2014
    ANSWER: Unwind it by 4-quarter turnsone full turn and check it. When you get close to ideal tension make quarter turn changes. Do not be concerned that spring is longer. by Harvey J a
    ANSWER: You have to much tension on the spring. The winding of the spring is to help lift the door.Take all the tension off the spring. Start winding the spring and check opening the door. When the door does not stop before being fully open the tension is correct. You also most likely have opening and closing tension adjustments on the electric door opener by the motor and light if supplied. Check your door opener manual for how to adjust it. There are also plenty of instruction video's online for all of these installations and adjustments. Note that the new spring should not be longer than the old one.Are you sure you ordered the right spring. Good luck! by Hal B a
    QUESTION: One repair guy said my springs were too small for the size door I have 16'X 84" wood door with row of windows.
