Garage door springs do the heavy lifting when opening and closing your door. Over time, these springs will sustain wear and tear, eventually needing replacement to restore your door’s smooth operation. Whether you want to upgrade or replace old springs, knowing what type you need will make the process easier.
In this guide, we’ll cover the different types of garage door springs to help you get a better understanding of your garage door system. We also tackled common spring issues and how you can extend its lifespan to minimize garage door spring repair.
How garage door springs work
Garage door springs counterbalance the weight of your door, which can range from 100 to 450 pounds, depending on its size and material. The torque stored on the springs assists the garage door opener motor in lifting your door, ensuring smooth closing and opening every time.
Think of torsion springs as a tightly coiled rubber band. When you twist it, the band stores energy and unwinds automatically when released. Garage door springs, especially torsion springs, work in a similar way when operating your door.
Please note that springs are available in various tension levels, calibrated for specific door weights. Too low and it will cause the door to slam shut or open slowly. Too high and it will make the door fly open suddenly.
Below, we discuss more of this and how torsion vs. extension springs differ.
Types of Garage Door Springs
Choosing the right type of springs ensures proper functionality and safety of your garage door systems. If you’re new to this component, here are the main garage door spring types, how they work, and which one you should get for your home:
1. Helical Spring
Helical springs are essentially a wire material coiled into a spiral or helix shape. The compressed coil structure allows the springs to extend or compress along a bar or axis.
Moreover, helical springs are available in different wire thicknesses, numbers of turns, coil diameters, and materials – all of which affect their durability and weight ratings.
Below are the main types of helical springs:
Torsion springs
Torsion springs are the most common springs used in garage door systems. It’s mounted at the top of your door and suspended on a fixed rod where it twists and untwists during operation.
Most garage doors use a pair of torsion springs to counterbalance their weight. It can be connected to a motor opener or simply assist with manual operation.
Types of Torsion Springs
There are several types of torsion springs, though not all of them are widely used in garage door systems. Here are some that you may encounter:
1. Standard Torsion Springs Ends
Standard torsion springs are the most common torsion springs you’ll find on residential garage doors. They sit on a metal shaft above your door and twist to balance its weight. If you have a typical two-car garage door, chances are you already rely on standard torsion springs.
2. Heavy-Duty Torsion Springs
Heavy-duty torsion springs are built for oversized or extra-heavy garage doors, such as custom wood doors. If your door feels heavier than most, these springs provide the lifting strength you need. They also last longer, making them a good choice if you want durability.
3. High-Cycle Torsion Springs
High-cycle springs are designed to last far longer than standard ones, often 50,000 cycles or more. If you and your family open and close the garage door many times a day, these springs save you from frequent replacements. They’re a smart investment for busy households.
4. Wagner Ends
Wagner ends are shaped to work with Wagner-style hardware. If you have an older garage door system, you may find these springs installed on your door. Because they’re not standard, you’ll need the right match if you ever replace them.
5. Mini Warehouse Ends
Mini warehouse torsion springs are made for roll-up doors in storage facilities and small commercial spaces. If you rent or manage storage units, you’ve likely used doors with this type of spring. They’re built to handle heavy use throughout the day.
6. Mcknee Ends
McKnee ends are a type of spring designed to fit shafts of different inside diameters. If your garage door setup uses unique shaft sizes, these springs make it possible to get a proper fit. They give you flexibility when standard sizing doesn’t apply.
7. Crawford Regular and T-Spring Ends
Crawford springs are common in Crawford garage door systems, often seen in Europe but sometimes in the U.S. If your system uses these, you’ll either have the regular ends or the “T” shaped ends that lock into matching hardware. You can’t swap them with standard torsion springs, so exact replacements are important.
8. Barcol Ends
Barcol ends are brand-specific springs for Barcol garage door systems. If you own this type of system, your springs must match the unique ends. They won’t work with standard garage door hardware.
9. Overhead Ends
Overhead ends are designed specifically for Overhead Door brand systems. If your garage door was installed by this brand, your torsion springs likely use this style. You’ll need these exact ends for replacements to ensure your system works correctly.
10. Rolling Steel Long Ends and Steel Loops
These torsion springs are used in large rolling steel commercial doors. If you manage a warehouse, loading dock, or industrial building, this is the type of spring your doors probably use. The long ends and various sizes let you handle heavy-duty, high-traffic applications.
Extension springs
Extension springs are the second main type of garage door spring, working by stretching and contracting as your door moves. They run along the sides of your garage door tracks and help lift the door’s weight. Here are the three main types you’ll find:
Types of Extension Springs
Here are the three main types of extension springs you’ll find:
1. Clipped-End Extension Springs
Clipped-end springs use metal clips at the ends to attach securely to the garage door hardware. These clips reduce stress on the spring itself, which helps the spring last longer compared to other designs. If you want a more durable option for your garage door, clipped-end springs are the strongest and most reliable choice.
2. Double-Looped End Extension Springs
Double-looped springs have two wire loops at the end that connect to the door’s hardware. The extra loop provides more strength than open-looped springs, but they’re not quite as durable as clipped-end springs. You’ll often find these on standard garage doors where homeowners want a balance of strength and affordability.
3. Open-Looped End Extension Springs
Open-looped springs have a single loop at the end that hooks directly to the hardware. They’re the easiest to install or replace because you don’t have to take apart as many parts of your system. However, they don’t last as long as clipped or double-looped springs, so you may need to replace them more often.
2. Leaf springs
Leaf springs are less common in modern residential garage doors but can still be found in certain systems, especially older or heavy-duty setups. They work by flexing and absorbing the door’s weight as it moves, helping balance the load.
Here are some of the common leaf spring types:
Elliptical leaf springs
Elliptical leaf springs are made by joining two semi-elliptical springs facing each other, forming an oval shape. They flex smoothly to balance the garage door’s weight and provide stable support. If your system uses this type, you’ll notice a sturdy setup designed for consistent, even lifting.
Semi-elliptical leaf springs
Semi-elliptical springs are the most common type of leaf springs. They curve like a half-circle and flex as your garage door moves up and down. If you have a heavier door, this spring type helps distribute the weight evenly, making it easier for you to operate it safely.
Quarter elliptical leaf springs
Quarter elliptical springs look like a quarter of a circle and are often mounted at one end of the door frame. They push upward to help lift the garage door, especially when space is limited. If your garage has a smaller or more compact setup, you may find this spring type in use.
Three-quarter elliptical leaf springs
Three-quarter elliptical springs combine a semi-elliptical spring with a quarter elliptical spring, creating a stronger and more flexible support. They’re used in doors that require extra lifting power without taking up too much space. If your garage door is unusually heavy but doesn’t allow for large springs, this design may be the solution.
Transverse leaf
Transverse leaf springs are mounted sideways, running across the garage door rather than along its length. They connect to both sides of the door and provide balanced lifting from the middle. If you see a spring stretching across the width of your garage, that’s likely a transverse leaf spring.
Common Issues with Garage Door Springs
Garage door springs wear down over time, and when they do, your door will show signs that something’s wrong. Here are some of the most common problems you may notice and what they mean:
1. Unbalanced doors
An unbalanced door means one side is heavier or doesn’t stay level when opening or closing. This often happens when one spring is worn out or broken, leaving the other spring to do all the work.
You can spot it if your door looks crooked or feels much heavier to lift. If ignored, the imbalance puts extra strain on your opener and can lead to sudden spring torsion or extension spring failure.
2. Slow or jerky movement
If your garage door moves unevenly, shakes, or feels sluggish, your springs may be losing tension. Springs are meant to keep the motion smooth, so any jerky movement signals they aren’t pulling evenly.
You’ll usually notice this when the door hesitates midway or rattles as it moves. Left unchecked, this can damage the door tracks and opener.
3. Visible gaps or rust
A gap in the coil of a torsion spring means the metal has snapped or stretched out, and the spring is no longer working. Rust is another common issue, as it weakens the metal and speeds up wear.
You’ll see this during a quick visual inspection above your door or along the tracks. Once a spring is cracked or corroded, it’s only a matter of time before it breaks completely.
4. Loud noises
Popping, grinding, or squealing garage door noises often come from springs under stress. A healthy spring operates quietly, so new noises usually mean the spring is worn, misaligned, or rubbing against other parts.
You’ll hear it most when opening or closing the door. Ignoring the sounds can lead to a sudden break, which is both dangerous and inconvenient.
Garage door spring replacement tips and guide
Replacing garage door springs is one of the most dangerous DIY repairs you can attempt. Springs are tightly wound and under extreme tension, which means a wrong move can cause serious injury.
Still, it helps to understand the process so you know what’s involved, why safety is critical, and when to call a professional.
Safety Precautions You Should Know
- High tension risk. Springs can snap or unwind suddenly, which could injure you if you’re in the way.
- Use proper tools only. You’ll need winding bars, clamps, and safety gear. Household tools like screwdrivers aren’t safe – never improvise!
- Disconnect the opener. Always unplug your opener so it doesn’t activate while you’re working.
- Work with the door closed. This keeps the door from falling on you while also reducing spring tension.
- Know your limits. If you feel unsure at any step, stop and call a garage door professional instead.
Garage door spring replacement: Step-by-step guide
Step 1. Identify your spring type
You’ll find torsion springs on a bar above the door. If you have extension springs, you’ll see it running along the sides of your tracks.
Step 2. Secure the door
Clamp the tracks or use locking pliers so the door doesn’t move on you while you’re working.
Step 3. Release spring tension (torsion only)
This step is extremely dangerous. If you don’t have proper winding bars, you should never attempt it.
Step 4. Remove the old spring
You’ll need to carefully disconnect the garage door spring from the brackets, cables, or center bar.
Step 5. Install the new spring
Position the new garage door spring correctly and reconnect it. With torsion springs, you’ll re-secure it on the shaft above your door.
Step 6. Tighten and adjust tension
Using winding bars, you’ll set the right tension so your door lifts evenly. For extension springs, you’ll need to align the cables properly.
Step 7. Test the door
Lift your door manually halfway. If it stays in place, the balance is correct. If it drops or shoots upward, you’ll need to adjust the tension.
Reminder: This guide is for informational purposes only and should not be taken as a step-by-step instruction manual. Garage door spring replacement is dangerous—always hire a garage door technician for repairs.
Maintenance Tips to Extend Lifespan
Taking care of your garage door springs helps them last longer and keeps your door running safely. Here are some simple maintenance tasks to extend the lifespan of garage door springs:
1. Lubricate springs regularly
Apply a garage door lubricant to your torsion or extension springs every few months. This reduces friction as the metal coils move, keeping them flexible and preventing rust.
Avoid using WD-40 or other penetrating oils to lubricate your garage door springs. Instead, use a silicone-based spray or a light lithium-based grease.
2. Check door balance
Disconnect your opener and lift the door manually halfway. If it stays in place, your springs are balanced. If it drops or shoots up, the springs may need adjustment.
Regular balance checks help you catch spring issues early before they strain your opener or cause uneven wear.
3. Inspect for rust or damage
Inspect your springs carefully for signs of rust, gaps in the coils, or stretched areas. Rust weakens the metal, and gaps mean the spring is already broken. Spotting these signs early gives you time to call a professional before the spring fails completely.
4. Keep the springs clean
Dust and debris can build up on your springs and tracks, causing extra friction. Make sure you wipe down the springs and surrounding hardware occasionally to keep everything moving smoothly. A clean system reduces wear and helps your springs do their job properly.
5. Schedule professional inspections
Even if everything looks fine, have a garage door technician inspect your springs once a year. A professional can test tension, spot hidden wear, and make safe adjustments that you can’t do on your own. This preventive step often saves you from costly emergency garage door repairs.
FAQs about garage door springs
How do I determine what garage door spring I need?
To determine the correct garage door spring, check the type of spring you currently have. Torsion springs sit above the door while extension springs run along the tracks.
Next, measure the length, inside diameter, and wire thickness of the spring, or provide the door’s weight and height to a professional. This ensures the replacement spring matches your door’s size and balance needs.
Can I replace garage door springs myself?
No, DIY spring replacement is not recommended. Springs are under extreme tension and can cause serious injury if mishandled. It’s best to hire a certified professional like Rock Garage Door Repair in Los Angeles for safe and long-lasting spring replacements.
How many springs should a 2-car garage door have?
A standard double garage door (16 feet wide) usually requires two torsion springs mounted on a shaft above the door. Having two springs ensures the weight of the door is evenly balanced and reduces strain on your opener.
Some lighter aluminum or single-layer steel doors may function with just one spring, but two springs are generally recommended for durability and smoother operation.
Should I replace both garage door springs at the same time?
Yes, you should replace both garage door springs together. Garage door springs are designed to wear out at roughly the same rate, so if one breaks, the other is usually close to failure.
Replacing just one spring creates an imbalance, makes the system less efficient, and can lead to premature wear on your opener. Replacing both at the same time saves you from another repair visit in the near future.
Are garage door springs universal?
No, garage door springs are not universal. Every spring is sized for a specific door weight, height, and setup. Installing the wrong spring size can make your door unsafe by causing it to slam shut, remain too light, or place extra strain on your opener.
To get the right spring, you’ll need accurate measurements or the door’s specifications. A professional like Rock Garage Door Repair can match the correct spring quickly and safely. Simply call us and we’ll source and install the garage door springs you need.
How long does it take to replace a garage door spring?
For a trained garage door technician, spring replacement usually takes 30 minutes to 1 hour, depending on the type of spring and the condition of the hardware. If both springs need replacement, the process can take slightly longer.
Attempting this as a DIY project may take much more time, and because of the safety risks, so it’s not recommended. Instead, you can call a professional like Rock Garage Door to handle it for you.
What happens if you put the wrong spring on a garage door?
If you use the wrong spring, your garage door won’t operate properly. A spring that’s too weak will make the door feel heavy and may keep you from opening it at all. On the other hand, a spring that’s too strong can make the door fly upward, or your garage door won’t close fully.
Either way, wrong springs will put extra strain on your opener and tracks, which can lead to expensive repairs and unsafe operation.
Is it OK to use WD-40 on garage door springs?
No, you shouldn’t use WD-40 on your garage door springs. WD-40 is a cleaner, not a true lubricant, so it will only quiet the springs temporarily before drying out.
If you rely on it, your springs won’t get the protection they need. Instead, use a silicone-based spray or lithium grease, which keeps your springs flexible, prevents rust, and helps your door operate smoothly.
Is it safe to adjust garage door springs?
No, it isn’t safe for you to adjust garage door springs yourself. Springs are tightly wound and store a lot of tension that can release suddenly if you handle them incorrectly. For your safety, you should always leave spring adjustments to a trained professional.
