To assure you are ordering the correct springs, read or review this page. The extra time should prove beneficial. Over the years we have discovered that informed customers are happier.
Standard residential torsion springs are found on a shaft above the center of the garage door. These springs typically come in 1 3/4", 2" and 2 1/4" inside diameters. If you have a broken torsion spring, read below to make the measurements you need, and then purchase a new garage door spring or springs.
Included below are a number of popular torsion spring topics, many of which you may want to consider before ordering a new standard torsion spring for your garage door.
A standard torsion spring has a stationary cone which secures the spring to the spring anchor bracket. Since this bracket is secured to the wall, the stationary cone, as its name suggests, does not move. The other end of the torsion spring has a winding cone. This winding cone is used when installing, adjusting, and uninstalling the springs. When installing the torsion spring, the coils of the spring are wound up to create a lot of torque.
Since these cables hold the weight of the garage door, the torque from the torsion springs does not dangerously spin the shaft until the spring is loose. Instead, the garage door weight slightly exceeds the lift produced by the torsion spring(s). (The lift is the amount of weight that each spring can raise off the ground.) As a result, a properly operating garage door with the right springs should not seem to weigh nearly as much as the garage door itself. When this principle holds true through the duration of the door's travel, the door is balanced.
With the help of the torsion springs, you should be able to operate the garage door manually without much trouble. Likewise, it does not take too much work from the garage door opener to lift the garage door. As the door opens (either manually or with the opener), the torque on the shaft keeps the cable tight on the cable drum. As a result, the cable winds up on the cable drum, allowing the torsion springs to unwind.
As the torsion spring unwinds, it loses some of its torque. Therefore, it also loses the amount of lift that it can produce. Vertical lift and high lift garage doors deal with this problem in a slightly different way, and you can read about How Vertical Lift and High Lift Garage Doors Work. Standard lift garage doors are almost universally used in residential garages, and are in the majority in commercial and industrial settings.
It all comes down to the cable drums. Standard lift cable drums have a flat portion for the cable, with one or two grooves that are a little higher. (These higher grooves are addressed in the link above.) As the garage door opens, the rollers slide along the track. The door transitions from the vertical track to the horizontal track.
When the top section is supported by the horizontal track, each spring does not need to support as much weight. Since the springs have unwound a little by this point, the amount of weight supported by the horizontal tracks roughly equals the lift that was lost from the decrease in torque in the torsion springs.
When the garage door is fully open, there is still about 3/4 to 1 turn still applied to each torsion spring. Since the bottom roller on the garage door typically rests on the curved portion of the track, the door will want to fall down. The extra torque in the torsion springs, though minimal in comparison to the torque when the garage door is closed, keeps the door open.
Included below are a number of popular topics that interest homeowners when considering torsion spring purchases. Though it may be helpful to consider these options, they do not apply to all garage doors.
If you have two torsion springs on your door, you should replace both of them. Most doors have springs with the same cycle life rating. In other words, when one spring breaks, the other spring will probably break before too much longer. Since you will be going to the trouble of changing one torsion spring, it is usually better to change your second spring as well. This will save you time in the garage as well as money on the shipping costs.
Some doors, however, have two springs with different dimensions. Many times, the cycle life of the broken spring is shorter than the cycle life of the unbroken spring. This means that you may still have another couple thousand cycles left on your unbroken spring. If you only change one spring now, you will probably need to change your other spring fairly soon down the road. Therefore, we recommend that you still replace both springs, but that you purchase springs with the same length, inside diameter and wire size.
If this is the case, each of your new torsion springs will need to lift 1/2 of the total lift of your two old springs. A matched pair of springs can be determined for you by using our Unmatched Springs calculator.
A lot of people have a garage door with only one spring on it and wonder whether they should upgrade to two springs. If the new torsion spring that you will install on your door has an inside diameter (ID) of 1-3/4" and a wire size of .250 or larger, we suggest that you convert to two torsion springs. The same holds true with a 2" ID and .2625 wire size or a 2-1/4" ID and .283 wire size.
The problem with having a larger wire size on a single-spring door is that the spring pulls on the shaft as the door opens and closes. This can cause serious problems in the future including cables breaking or peeling off the drums and steel sections getting damaged. While it usually costs $5-$10 to convert over to two springs, it can save a lot of money down the road.
One question that people frequently ask when converting to two springs is whether they need a second bearing for the second spring. The answer is no. The purpose of the bearing is to keep the stationary cone centered on the shaft so that the spring is centered on the shaft. Since the stationary cones from the two springs will be secured to each other in the process of securing the springs to the spring anchor bracket, the second spring does not need a bearing. Additionally, adding a second bearing will probably break one or both of the stationary cones.
For more information to help you decide whether to have one spring on your garage door or two, see our One Torsion Spring or Two? page.
If your two spring dimensions are not the same, we recommend switching to a pair of springs with the same dimensions. While it is possible to use unmatched springs, you are more likely to get the maximum cycle life out of a pair of springs when they are the same length, wire size and inside diameter.
If you purchased two torsion springs with different dimensions, it is possible to maximize the cycle life on the two springs. See our Maximizing Cycle Life on Unmatched Torsion Springs page for more information.
If you currently have unmatched springs and wish to convert to a pair of matched springs, or if you want to read how to use unmatched pairs, see our Using Torsion Springs with Different Lifts page.
The cycle life of a torsion spring refers the to rating regarding how many cycles (the door opening and closing is one cycle) the spring should make before it breaks. The cycle life rating does not account for premature breakage, often caused by chips in the steel or highly corrosive environments.
The standard cycle life in the garage door industry is 10,000 cycles. Spring under 10,000 cycles are considered overstressed and are not recommended for use. If you would like to have more than 10,000 spring cycles, your new torsion springs will need to have a larger wire size. The larger the wire, the longer it will take for the spring to break as thicker steel requires more bending before it breaks.
If you increase the wire size of your springs, you will also need to increase the length to keep the same lift and torque rating. On narrower, heavier doors it may also be necessary to increase the inside diameter to provide enough space on the shaft for the springs to fit.
When you search for a specific torsion spring, compatible springs with the same lift but a different cycle life will be listed. You can upgrade your torsion springs by purchasing one of these springs instead of spring matching your old dimensions. If you are browsing instead by door height, you can look under larger wire sizes to find a compatible spring with more cycles.
In recent months, there has been a rising concern about the type of steel used in springs. For example, Chinese imported steel and springs are often more brittle or not properly heat-treated and they fail prematurely. At DDM Garage Doors, we make it our primary concern to not only help people figure out how to repair their doors, but also to provide excellent products for our customers. Therefore, if you purchase a spring from us, you can rest assured that all our springs are made with high-quality steel from the United States. The aluminum alloy cones, however, are made in China, but we have not seen any product failures with these.
We supply oil-tempered coated torsion springs. We also sell galvanized torsion springs for the same price, but we do not recommend them in most circumstances. Over time, galvanized torsion springs lose more tension than oil-tempered springs, often losing one to two turns by the time they break. This can create service problems as well as shortening the life of the opener. There are times when galvanized springs last longer, simply because they lose more tension. The same longer life can be achieved by not winding oil-tempered springs as much, but we don't recommend this as doing so can damage your opener. If your door is in a highly corrosive environment, galvanized torsion springs may help to prolong the life of the springs. To prevent against premature breakage, we still recommend oiling galvanized springs as we do oil-tempered springs. For more information about galvanized and oil-tempered torsion springs visit our blog.
To learn more about how these systems work, see our How Vertical Lift and High Lift Doors Work page. If you are interested in the work involved when performing a high-lift conversion, check out our Garage Door High-Lift Conversion tutorial.
If you are interested in converting your standard lift garage door to a high-lift door, please find the dimensions specified in the High-Lift Conversion Tutorial and fill out the form on our Garage Door High-Lift Inquiry page. After filling out the form, you will see options for the spring cycle life for your conversion kit and the total cost; we will then contact you to complete your order.
Custom roofline lift conversion kits are also available. Most of these doors travel vertically for a foot or two before reaching the curved part of the horizontal track. Rather than rolling back parallel to the garage floor, the door instead continues to roll back and upward, following the pitch of the ceiling. This option is only available for garages with ceilings that pitch up and away from the door. These conversion kits are also available - visit our High-Lift Inquiry page to receive a quote for a custom roof-line high-lift kit.
If you have enough space in your garage for your door to open vertically and are instead interested in a custom vertical-lift conversion kit, please contact us so we can determine the parts you need and the cost of your new kit.
Follow the instructions below to make the proper measurements when looking to buy new torsion springs. Once you have your measurements, you can contact us or use our Find My Spring Database™ and the bottom of this page to order new springs.
You will also need your track radius. As pictured, this is the radius of the curved portion of your horizontal track. While this varies from door to door by only a few inches, a larger track radius requires more turns on the spring and therefore slightly increases the lift of a spring while slightly decreasing the cycle life rating.
Your door height will also be a necessary dimension when finding new torsion springs.
Torsion springs have five primary characteristics: 1. inside diameter (ID), 2. wire size, 3. length, 4. wind, and 5. type of ends. Determine all of these measurements for each spring that you are replacing.
If you have two springs, we recommend that you replace both springs on your door. If this is the case, be sure to measure both springs. If after measuring you find that your springs are unmatched, you can use our Unmatched Springs Calculator to find a pair of matched torsion springs.
Each of these measurements needs to be taken carefully, so be sure to read our How to Measure Torsion Springs page.
If you have a 4" diameter cable drum and you have measured the torsion springs you are replacing, you can enter your spring dimensions in our Find My Spring Database™ to purchase new torsion springs.
Once you have your garage door weight, door height, cable drum number, and track radius, you can purchase new springs. If you have a 4" diameter cable drum, you can browse our Torsion Spring Prices. Rather than entering specific spring dimensions, you can browse springs for your door height based on the spring's lift. If you have two springs, the lift of each spring will be half of your door weight. You can browse by either 1-3/4" or 2" inside diameter (it does not matter which one you choose); only purchase 2-1/4" ID springs if you have a Raynor door as you may otherwise experience hardware compatibility problems.
In order to determine the weight, we will also need to know how many struts are on the door. These are silver metal bars that run across the length of the door. They will be either be about 2-1/4" or 3" off the inside surface of the door.
Once we determine the weight of your door, we will need to find springs that will match your door. To do this, you will need to provide your door width and height, your track radius and your cable drum number as mentioned before.
After you have gathered this information (door manufacturer and model number, number of struts, door width and height, cable drum number, and the track radius), contact us so that we can find suitable replacement springs for your door.
If you do not have a 4" diameter cable drum, you will need to contact us so that we can determine the springs you need.
If you have a high-lift or a vertical-lift garage door, our database will not give you accurate spring information. If you can find an exact replacement spring in our database, it will work. Because of the extra turns required on the spring for the lift design, the cycle life will not be accurate. If you are instead finding new springs from your door weight, you will have to contact us so that we can find replacement springs for your system.
If your garage door is greater than 8' tall, please contact us so that we can find replacement springs for you.
If you cannot find your current spring in our Find My Spring Database™, your spring may be overstressed for your door height. Many manufacturers and installing garage door companies are cutting corners and installing garage door springs with cycle lives that fall below the 10,000-cycle industry standard. Try changing your door height to 6' 6". If you then see the spring, consider using one of the suggested cycle life upgrades for the 6' 6" high door for your taller door. If you can't find it there contact us. We will find their torque ratings and recommend suitable higher cycle replacements. We may also ask questions about your garage door to make sure your measurements are correct. We will sell springs rated below the 10,000-cycle minimum, but we will not accept returns on any of these springs.
Garage Door Torsion Springs are normally centered above the garage door on a one inch shaft. At one end of the spring is the winding cone that is secured to the shaft with set screws. At the other end of the spring is the stationary cone. This is secured to the spring anchor bracket, which is secured to the header. On two-spring assemblies the stationary cones of both springs are mounted back to back to the spring anchor bracket. The shaft running through the springs transfers tension from the springs to the cable drums at the end of the shaft. These drums pull on the cables, which pull on the bottom of the door to balance the weight of the garage door.
All the residential torsion springs we provide are wound with 1/2" rods, usually 18 inches. You can buy 1/2" X 36" rod at almost any hardware store and cut one in half. If you would like for us to include a pair of winding rods in the order you can follow the links at our garage door tools page.
Customers have also asked us about whether they should replace their cables, end bearing plates and center bearings. Cables normally don't need to be replaced. It would be good, however, to check for frays along the length of each cable and for rust at the bottoms if they are subject to salt corrosion. If needed, you can purchase new cables on our Garage Door Cables page. The end bearing plates rarely need to be replaced. The Chinese made some bearings several years ago stamped with the letters "ADH." These, along with some of the old McKee Door end bearings are about the only ones we've seen wear enough to warrant replacing. It is even rarer when a center bearing needs to be replaced. In our experience it's probably only one in 5,000 or more spring replacements where a new bearing would be needed. That's usually only on center support brackets that were not installed plumb or perpendicular to the header. A drop or two of oil is usually all that most center bearings ever require. If needed you can purchase these parts on our Garage Door Bearings & Bearing Plates page.
Clopay and Ideal make EZ-Set springs that wind with a drill. These springs are specially gapped and they are made differently from the springs in our database program. If you have EZ-Set Springs, you can order the spring or springs you need on our EZ-Set Garage Door Torsion Springs page. However, if you live near the coast, and if you have a wind-rated door, you will need to call or e-mail us to order the correct springs.
Garage door torsion springs on larger sectional and rolling steel doors come with many additional inside diameters. For information and prices visit our Commercial Torsion Spring page.
When ordering springs for the older style Overhead Door brackets, let us know in the comment section. Notice in the picture that standard cones are wider where the bolts pass through them. The one inch bolts used in the older Overhead Door cones are not long enough to secure the cones to the bracket. We will provide longer bolts and wider flange nuts at no charge to help with your project.
We don't recommend reusing the cones because they are dangerous; the hole sizes for the winding bars are inconsistent.
However, if you do decide to order two inch inside diameter springs without cones, let us know in the comment section if you have Overhead Door cones so we can bend up the ends of the spring wire to fit in the clips. These clips keep the spring from spinning off the cones. Standard cones screw into the spring and are held in place by friction.
At DDM Garage Doors we strive to minimize shipping time and shipping costs. Getting the springs to customers for their weekend DIY projects without extra shipping costs is a priority.
National Sales. When ordered by 3:30 P.M. CT Monday through Friday, all the springs in our database are normally available for shipping on the same day by UPS or FedEx from our warehouse in West Chicago. The cut off time for USPS is 2 PM CT. If you have a preference please note that when ordering. Expedited shipping is also available. Please call for options and pricing. We also ship internationally.
Midwest. In all of Illinois, in most of Iowa, Wisconsin, Michigan and Indiana, and in selected parts of Missouri, Kentucky, Ohio and Minnesota, springs are usually delivered in one day - including Saturday - at no extra cost. In this select midwestern area you can usually order on Friday and get the springs on Saturday.
California. We ship springs to California either from West Chicago or from a manufacturer in Visalia, California. Our shipping decision is based on three factors: controlling product and packaging quality, minimizing the cost of additional packaging, and delivery time.
On Mondays and Tuesdays we ship springs over 27" long from West Chicago by FedEx for delivery by Saturday. If the springs are under 27" long, we ship by Priority Mail with normal two to three day delivery.
On Wednesdays springs under 27" normally ship by Priority mail and springs over 27" ship from our supplier in California by UPS.
On Thursdays all springs are shipped from the manufacturer in California by UPS with normal expected delivery on Friday if they are ordered by 11 AM Pacific Time.
On Friday we follow the Monday schedule.
If you need the springs sooner let us know in the comment box of your order, and we will try to ship from our supplier in California. When shipping springs from California, however, additional parts such as cables and winding bars require separate packages and additional shipping charges reflected on your cart invoice. This may also require extra shipping time as well. If the only additional part you need is winding bars, you can avoid the extra shipping time and costs by picking them up at a hardware store.
Customer Pickups. In three parts of the country you can also save on shipping and get your springs same or next day. Many customers in the greater Chicago area stop by to pick up springs at our warehouse in West Chicago. Customers also purchase springs from us and pick them up next day from a supplier in Mesa, AZ or from a different supplier in Maumee, OH. Just call us to make arrangements. Our California supplier does not allow customers to pick up springs.
