Standard residential torsion springs are found on a shaft in a higher place the center of the garage door. These springs typically come in i 3/4", 2" and 2 1/4" inside diameters. If you accept a broken torsion spring, read below to make the measurements you need, then buy a new garage door spring or springs.
Included below are a number of pop torsion bound topics, many of which yous may desire to consider before ordering a new standard torsion spring for your garage door.
A standard torsion leap has a stationary cone which secures the jump to the spring anchor bracket. Since this subclass is secured to the wall, the stationary cone, as its name suggests, does not movement. The other end of the torsion bound 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 jump are wound up to create a lot of torque.
The torque transfers from the shaft to the cable drum, pulling the cablevision and the lesser of the garage door upward.
Since these cables concord 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 past the torsion bound(due south). (The lift is the amount of weight that each spring can enhance off the footing.) As a result, a properly operating garage door with the right springs should non seem to counterbalance virtually equally much as the garage door itself. When this principle holds truthful through the duration of the door'south 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, information technology does not have 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 event, the cable winds upward on the cable pulsate, assuasive the torsion springs to unwind.
As the torsion jump unwinds, information technology loses some of its torque. Therefore, it besides loses the amount of lift that it can produce. Vertical elevator and high elevator garage doors deal with this problem in a slightly unlike way, and yous 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.
Information technology all comes down to the cablevision drums. Standard lift cable drums have a flat portion for the cable, with i 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 forth the runway. The door transitions from the vertical track to the horizontal track.
When the horizontal runway supports the top section, each spring does non need to back up equally much weight. Since the springs accept unwound a lilliputian past this signal, the corporeality of weight supported by the horizontal tracks roughly equals the elevator that was lost from the decrease in torque in the torsion springs.
When the garage door is fully open, there is still about iii/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 actress 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 leap purchases. Though it may be helpful to consider these options, they do not apply to all garage doors.
Supercede Both Torsion Springs?
If you have two torsion springs on your door, you should replace both of them. Almost doors take springs with the same cycle life rating. In other words, when one leap breaks, the other leap will probably break before also much longer. Since yous will be going to the trouble of irresolute ane torsion jump, it is usually meliorate to change your second spring as well. This will save you time in the garage every bit well as coin on the shipping costs.
Some doors, however, have two springs with different dimensions. Many times, the wheel life of the cleaved bound is shorter than the cycle life of the unbroken leap. This means that you may still have another couple thousand cycles left on your unbroken spring. If you simply change one spring now, you will probably need to modify your other spring fairly soon down the road. Therefore, we recommend that you still replace both springs, simply that you buy springs with the same length, inside bore and wire size.
If this is the case, each of your new torsion springs will need to lift 1/ii of the total elevator of your two old springs. A matched pair of springs tin be determined for you by using our Unmatched Springs reckoner.
For assistance determining whether you should replace both springs on your door, run into our Torsion Leap FAQ's page. Yous can also read more almost springs with dissimilar dimensions.
One Spring or Ii?
A lot of people accept a garage door with only spring on it and wonder whether they should upgrade to ii springs. If the new torsion spring that yous will install on your door has an within bore (ID) of 1-3/four" and a wire size of .250 or larger, we propose that you convert to two torsion springs. The aforementioned holds true with a ii" ID and .2625 wire size or a 2-1/iv" ID and .283 wire size.
The problem with having a larger wire size on a single-leap door is that the bound pulls on the shaft as the door opens and closes. This tin crusade serious problems in the future, including cables breaking or peeling off the drums and steel sections getting damaged. While it ordinarily costs $5-$ten to convert over to ii springs, it can save a lot of money downward the road.
One question that people oft ask when converting to two springs is whether they demand a 2nd begetting for the 2d 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 ballast bracket, the second spring does non need a bearing. Additionally, adding a 2nd begetting will probably break one or both of the stationary cones.
For more information to help y'all decide whether to have one spring on your garage door or two, meet our I Torsion Spring or Two? page.
Different Spring Dimensions?
If your two bound dimensions are not the same, nosotros recommend switching to a pair of springs with the same dimensions. While it is possible to utilise unmatched springs, yous are more likely to get the maximum cycle life out of a pair of springs when they are the aforementioned length, wire size and inside diameter.
If you purchased two torsion springs with dissimilar dimensions, information technology is possible to maximize the cycle life on the two springs. See our Maximizing Cycle Life on Unmatched Torsion Springs page for more data.
If you currently have unmatched springs and wish to convert to a pair of matched springs, or if you desire to read how to use unmatched pairs, see our Using Torsion Springs with Dissimilar Lifts page.
Longer Life Torsion Jump Options
The cycle life of a torsion spring refers the to rating regarding how many cycles (the door opening and endmost is one cycle) the leap should make before information technology breaks. The cycle life rating does not business relationship for premature breakage, often caused past fries 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 lot would similar to accept more than 10,000 bound cycles, your new torsion springs volition need to have a larger wire size. The larger the wire, the longer it will take for the spring to intermission equally thicker steel requires more angle earlier it breaks.
If you increment the wire size of your springs, you will too need to increase the length to go on the same elevator and torque rating. On narrower, heavier doors it may also be necessary to increase the inside diameter to provide plenty 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. Y'all tin upgrade your torsion springs past purchasing one of these springs instead of spring matching your old dimensions. If you are browsing instead by door height, you tin can expect under larger wire sizes to detect a compatible spring with more than cycles.
Spring Steel
We supply oil-tempered coated torsion springs. We can as well provide galvanized torsion springs, only we do not recommend them in most circumstances. Over fourth dimension, galvanized torsion springs lose more tension than oil-tempered springs, often losing 1 to 2 turns by the fourth dimension they intermission. This can create service bug equally well as shortening the life of the opener. There are times when galvanized springs last longer, simply considering they lose more than tension. The same longer life tin can be accomplished by not winding oil-tempered springs as much, but we don't recommend this every bit 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 foreclose against premature breakage, nosotros still recommend oiling galvanized springs as we do oil-tempered springs. For more than information almost galvanized and oil-tempered torsion springs visit our blog.
High Lift and Vertical Lift Conversions
Custom high-lift conversion kits are bachelor for buy.
To learn more about how these systems work, see our How Vertical-Elevator and Loftier-Lift Doors Work folio. If you are interested in the work involved when performing a high-elevator conversion, bank check out our High-Lift Garage Door Conversion tutorial.
If you are interested in converting your standard lift garage door to a loftier-lift door, please notice the dimensions specified in the High-Lift Garage Door Conversion tutorial and fill out the form on our Garage Door High Lift & Vertical Lift Inquiry page. After filling out the form, you volition run across options for the leap cycle life for your conversion kit and the total cost; we volition then contact you to consummate your order.
Custom roofline lift conversion kits are too available. Well-nigh of these doors travel vertically for a pes or ii before reaching the curved part of the horizontal runway. Rather than rolling back parallel to the garage flooring, the door instead continues to roll back and upward, post-obit the pitch of the ceiling. This pick is only available for garages with ceilings that pitch upward and away from the door. These conversion kits are also bachelor - visit our Garage Door Loftier Lift & Vertical Lift Inquiry page to receive a quote for a custom roofline loftier-lift kit.
If y'all have enough space in your garage for your door to open up vertically and are instead interested in a custom vertical-elevator conversion kit, delight contact us and so we can make up one's mind the parts y'all 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, y'all can contact us or use our Find My Spring Database™ and the bottom of this page to society new springs.
Measuring Your Garage Door
What is a balanced garage door?
A balanced garage door will:
1. Stay downward when close
2. Stay up when open
iii. Not move when in the middle
This cable drum says "OMI 8". In that location is typically a 4 or an eight on 4-inch diameter cable drums. If the drum says 525 or 575, the diameter is larger.
Concur a level at the bottom of the rails junction, and measure out the distance from the center of the horizontal track to the peak of the level.
You volition also need your track radius. As pictured, this is the radius of the curved portion of your horizontal runway. 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 bicycle life rating.
Your door height will besides be a necessary dimension when finding new torsion springs.
Method 1: Measure your existing springs
Torsion springs have five chief characteristics: 1. within bore (ID), two. wire size, 3. length, iv. air current, and v. type of ends. Decide all of these measurements for each leap that you are replacing.
If y'all take two springs, we recommend that yous replace both springs on your door. If this is the instance, be certain to measure both springs. If after measuring y'all find that your springs are unmatched, you lot tin use our Unmatched Springs Calculator to find a pair of matched torsion springs.
Each of these measurements needs to exist taken carefully, and then exist certain to read our How to Measure out Garage Door Torsion Springs page.
If yous accept a 4" bore cablevision drum and y'all have measured the torsion springs you are replacing, you can enter your bound dimensions in our Notice My Spring Database™ to purchase new torsion springs.
Method 2: Weigh your door with an analog scale
Use an analog scale to weigh your door.
If you cull instead to weigh your garage door, delight follow our How to Weigh a Garage Door tutorial. Be sure to use an analog bathroom scale to weigh your door equally well-nigh digital scales do non alter their reading after a few seconds if the weight changes.
Once you have your garage door weight, door height, cablevision drum number, and track radius, you lot tin purchase new springs. If you have a iv" bore cable drum, you tin 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 2 springs, the lift of each spring will exist half of your door weight. You can browse by either 1-iii/4" or two" inside diameter (it does not matter which one you lot cull); just purchase 2-1/four" ID springs if you have a Raynor door as you may otherwise experience hardware compatibility problems.
Method 3: Determine the manufacturer and model number
Virtually garage doors have a characterization on the bottom section that gives the serial number.
If y'all choose to permit united states of america to determine the springs you need based on your door manufacturer and model number, nosotros will first discover your door weight. Sometimes this information is located on the within of the garage door, and sometimes it is located on the side. If it is on the side, information technology may be difficult to read every bit the track is usually in the way. You may also be able to notice the manufacturer and model number if y'all have paperwork from when you bought the door.
In order to determine the weight, nosotros volition 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 volition be either be about 2-1/iv" or 3" off the inside surface of the door.
Once we make up one's mind the weight of your door, nosotros will need to notice springs that will match your door. To practise this, you volition need to provide your door width and tiptop, your runway radius and your cable pulsate number as mentioned before.
After you accept gathered this information (door manufacturer and model number, number of struts, door width and height, cablevision pulsate number, and the track radius), contact us so that we tin can find suitable replacement springs for your door.
Special Orders
If you do not have a four" diameter cable drum, you will need to contact us and so that we can determine the springs you lot need.
If you have a high-elevator or a vertical-lift garage door, our database will not give you lot accurate jump information. If you can find an exact replacement spring in our database, it will work. Because of the extra turns required on the leap for the elevator design, the bicycle life will not be accurate. If yous are instead finding new springs from your door weight, you will have to contact u.s. so that we can notice replacement springs for your system.
If your garage door is greater than 8' alpine, delight contact usa so that we can find replacement springs for you.
If y'all cannot find your electric current spring in our Find My Spring Database™, your spring may exist overstressed for your door pinnacle. Many manufacturers and installing garage door companies are cutting corners and installing garage door springs with cycle lives that fall below the 10,000-bike manufacture standard. Attempt irresolute your door top to 6' half dozen". If you then see the bound, consider using one of the suggested bike life upgrades for the half dozen' six" high door for your taller door. If you tin't find information technology there contact us. We will find their torque ratings and recommend suitable higher bicycle replacements. We may also ask questions about your garage door to make certain your measurements are correct. Nosotros will sell springs rated below the 10,000-cycle minimum, but nosotros will not accept returns on any of these springs.
Buy Standard Torsion Springs with our Find My Spring Database™
Garage Door Torsion Springs are normally centered above the garage door on a one inch shaft. At 1 end of the bound is the winding cone that is secured to the shaft with set screws. At the other end of the jump is the stationary cone. This is secured to the leap anchor bracket, which is secured to the header. On two-leap assemblies the stationary cones of both springs are mounted back to back to the jump anchor bracket. The shaft running through the springs transfers tension from the springs to the cablevision drums at the end of the shaft. These drums pull on the cables, which pull on the lesser of the door to residuum the weight of the garage door.
When you cannot utilize our Observe My Spring Database™:
1. Your cablevision drums are not iv" in bore.
2. You have a high-lift or vertical-lift door.
3. You have a commercial door.
4. Your door is greater than 8' loftier.
If yous cannot use our database, contact united states of america with the information listed above.
Winding bars are necessary for replacing your springs.
All the residential torsion springs nosotros provide are wound with ane/2" rods, ordinarily 18 inches. Yous tin can buy 1/2" X 36" rod at almost any hardware store and cutting one in half. If you would like for united states of america to include a pair of winding rods in the gild you tin follow the links at our Garage Door Tools & Technical Support page.
Customers have also asked us about whether they should replace their cables, end begetting plates and center bearings. Cables normally don't need to be replaced. It would exist good, nevertheless, to cheque for frays along the length of each cablevision and for rust at the bottoms if they are subject field to salt corrosion. If needed, you can buy new cables on our Garage Door Cable and Fittings folio. The end bearing plates rarely demand to be replaced. The Chinese made some bearings several years agone stamped with the letters "ADH." These, along with some of the former McKee Door finish bearings are about the only ones we've seen clothing enough to warrant replacing. It is even rarer when a center bearing needs to be replaced. In our feel it'south probably just one in 5,000 or more leap replacements where a new begetting would be needed. That'southward commonly just on center back up brackets that were not installed plumb or perpendicular to the header. A drop or two of oil is commonly all that well-nigh center bearings ever crave. If needed, you can buy these parts on our Garage Door Bearings & Bushings page.
Torsion springs for EZ-Set up systems cannot be purchased through our database.
EZ-Set Springs: Do Not use this database
Clopay and Platonic make EZ-Fix 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, yous can order the spring or springs you need on our EZ-Prepare Garage Door Torsion Springs page. Still, if you lot live near the declension, and if yous have a wind-rated door, you volition need to telephone call or email u.s.a. to social club the correct springs.
Commercial Torsion Springs
Garage door torsion springs on larger exclusive and rolling steel doors come with many additional inside diameters. For data and prices visit our Commercial and Industrial Torsion Springs page.
Overhead Door Cones
Springs used with Overhead Door cones need to have their ends bent upward to fit in the clips.
When ordering springs for the older way Overhead Door brackets, let u.s.a. know in the comment section. Notice in the picture that standard cones are wider where the bolts pass through them. The 1 inch bolts used in the older Overhead Door cones are not long plenty to secure the cones to the bracket. We will provide longer bolts and wider flange nuts at no charge to help with your projection.
Nosotros don't recommend reusing the cones considering they are dangerous; the hole sizes for the winding bars are inconsistent.
However, if you do decide to order two-inch inside bore springs without cones, allow us know in the annotate section if y'all accept Overhead Door cones so we can bend upward the ends of the jump wire to fit in the clips. These clips keep the spring from spinning off the cones. Standard cones spiral into the spring and are held in identify by friction.
Shipping Times
Delight Note. Due to COVID shipping times are non guaranteed, even on next day and 2d 24-hour interval shipments. Normal times do not apply.
At DDM Garage Doors, Inc. we strive to minimize shipping times and shipping costs. Getting the springs to customers for their weekend DIY projects without extra aircraft costs is a priority.

How To Mensurate Torsion Springs * How to Replace Garage Door Springs (2 Springs) * How to Replace Garage Door Springs (1 Jump) * How To Convert Within Diameters
Of import NOTICE: COVID has interrupted international supply chains resulting in an unprecedented rising in cone costs. Cones never wear out. To avoid the extraordinary price we recommend ownership springs without cones and reusing your old cones as we show on our Torsion Spring Cone Replacement tutorial and in our newest video beneath. If replacing the cones is too dificult, and if you are local, you lot tin bring your springs to u.s.a. and we tin can exchange your cones. The labor charge for this is half the cost of new cones.
The savings is particularly noticeable on the two 1/4" ID springs because Raynor'due south OEM cones cost 3 one/2 times as much as the 2" cones. For example, the 2 1/4" - .225 - 22" jump costs $175.22. A two" ID spring with the same wire, lift and cycle life, costs but $110.75 as of January 15, 2022. For ii springs yous would salve $128.94. You can convert your springs to 2" ID past using our Bound Inside Diameter Converter. We as well recommend y'all social club 1 of our Jump Ballast Bracket Kits to avoid possible compatibility problems.
