Each time you hit press the remote to open your garage door, the opener gently lifts the door and lowers it back once you are in. Yet, it comes unexpectedly for you to notice that it's not the opener doing the heavy work.

Rather, it's the garage's door starters and regulators at work. They start the door lifting movement and regulate it for smoothness and optimal speed. So, it's not the opener opening the door. All credit falls to garage door springs.

And so, there is the extension spring or the torsion spring. In this guide, we will comprehensively explore the two options. See where they are best used and what they offer.

Extension Springs

Standard, yet old-fashioned, extension springs use lingers in older homes where they are rooted on the sides of sectional doors. These springs connect to puller systems running along garage door walls and thus are connected on cables.

Their design features a single, double, or clip mechanism. Even so, they only last up to 10,000 cycles due to their proneness to wear and tear.

Understanding Extension Spring Mechanisms

Upon closure, the springs absorb some of the door weight, storing it as potential energy. The extension spring will release this energy upon opening to lift the door. Understand this: the door is a couple of hundred lobs, making lifting without springs unconceivable.

Following this, garage doors commonly employ two extension springs installed above the perpendicular tracks. Even so, the lighter door could use one spring.

How to Get the Right Garage Door  Extension Spring?

You can identify the right spring by the color codes or by the door mass. Color codes mean precision in the buying process. The code is attached at the end of the spring, guiding you toward getting the correct spring as long as you have your garage door weight in mind.

Now, we remain with the old-fashioned use of clamps and bathroom scales. They help in figuring out the door mass so long as you get the clamps under the rollers. Then, slowly unplug the extension spring. Afterward, you may have to get the doors edge upon the scale. Remember the weight in the display will be the correlation of the spring size needed.

Are Extension Garage Door Springs Worth It?

An extension spring is slightly on budget and best if you have small doors.  However, they don't keep much energy, so you will need about two springs for safety (failsafe and even stress distribution) to get the job done. As for maintenance, you will need a pro installer to do it for you.

On your end, you can only observe the weird noises and tension when the door is in use. The extension springs can last up to a decade if properly maintained, provided the cycles are two per day.

Torsion Springs

With a torsion spring, there is a connection to metal cones and tubes instead of pulleys. They operate parallel to the garage door along the metal shafts connecting to the cable drums on the corners of the garage.

Metal doors mainly use torsion springs, but heavy garage doors require two. Torsion spring turns rather than extend and will last up to 25000 turns. Even so, they allow more precise control and balance than extension springs.

Pathway to Choosing Torsion Spring

Do you need torsion springs? Here are tips on getting the right torsion spring for your garage door. Read on.

Know the Wire Size

You have to measure the length of the spring and ensure it falls within 10 to 20 coils. Provided you have the values, all you have to do is check your manufacturer's wire chart and then select the matching spring.

Measure the Interior Diameter Length

Occasionally, the diameter values will be written within the springs. The reading is usually rounded to the nearest sixth inch. But when there are no readings about the diameter, you will have to remove the spring and obtain the readings by yourself.

Obtain the General Length

You can get the right torsion spring if you know its general length. That means measuring it from end to end to determine its winding capacity. You have to round off the reading to the closest quarter inch. A shorter spring won't open the door; it will be best to measure the length when the door is shut.

Figure out the Wind's Direction

Direction matters, especially if you have to get your spring in full working order. It affects the spring rotations, its torque, tension, and overall safety, which are all critical for garage door applications.

Correct wind direction ensures alignment with intended use and system compatibility, thus avoiding unsafe operation on so-called wrong-way winds (clockwise).

Wind direction checking visually checks coil slopes when held vertically; coils moving up and to the right side denote a right-hand wind (clockwise).

Alternatively, check for gaps at the spring's end—right side gaps denote right-hand wind ostensibly labeled by manufacturers' part numbers to provide insights. Comparing replacements with old springs helps maintain consistency, as do consulting experts or manufacturers who clear uncertainties.


Is the Right Wind or Left Wind Torsion Spring Better?

Did you know torsion springs come in two variants? Yeah, that's right, it’s the right wind and left wind. Generally, this difference goes unnoticed; as such, the placement and function of the springs are important.

So, if your system has two torsion springs, the one on the left side is normally a right wind while the one on the right side is a left wind. This rule follows patterning to allow for the proper operation of any garage door or any system in which the springs are used.

The choice between the two will depend on the spring you need to replace. Assuming you got a single spring setup, it's still the left wind for a spring on the left side and the right wind on the right side. Mistaking the direction of the wind can lead to mishaps and reduced longevity.

Torsion Garage Door Spring Lifespan

Several user feedbacks show torsion spring hitting about 15,000 cycles. Yet if you get your garage door running twice daily, you can enjoy four decades of nearly 30,000 cycles. So, the extension on this spring's life makes it a good choice for high-traffic doors.

Either way, you must remember that Its longevity depends on factors like maintenance and usage patterns, not a fixed timeline.

Maintaining Garage Door Springs

It's important to check for any signs of wear or rust to keep the torsion or extension garage springs in condition. Apply a silicone-based spray to lubricate the springs and reduce friction. Ensure that your garage door operates smoothly without any jerking or imbalance, as this could strain the springs.

It's best to hire a professional for any repairs, adjustments, or replacements of attempting them yourself. Also, remember to keep the area around the springs from debris accumulation. By performing checks and seeking care, you can ensure that your garage door operates safely and efficiently while extending the lifespan of your springs.

Should You Choose Extension Springs or Torsion Springs for Your Garage Door?

Regarding the age debate of whether torsion springs are superior to extension springs, we often find ourselves delving into a realm of exploration. Upon examination, it becomes clear that torsion springs have notable advantages which make them stand out. Join me as we uncover why torsion springs often emerge as the preferred choice.


Safety is a factor that sets the stage for this discussion. Torsion springs hold an advantage in terms of safety. Their design, tucked securely within a tube, provides an added layer of protection that extension springs lack.

Extension springs' constant stretching and contracting can lead to wear and tear over time. What's worse is that when these extension springs snap, they can become projectiles, posing a threat to those. On the contrary, torsion springs avoid this energy accumulation, creating an environment.



Maintenance, the other factor in this equation, amplifies the case for torsion springs. Extension springs get bashed as maintenance issues with their assortment of parts and components. So, picture two extension springs flanking either side of your garage door versus a single torsion spring elegantly positioned above the door.

"The first option, distinguished by its complex design and numerous points where issues can arise, is more likely to require maintenance assistance due to the increased chances of encountering problems. On the other hand, torsion springs, known for their durability and strength, remain unyielding in the face of these challenges."



On garage door operations, torque is the stand-out contestant. And so, torque harnessing torsion springs uses a modern method that uses a twisting motion to power your garage door. On the other hand, extension springs rely on the precarious accumulation of expanding energy.

Expect to raise eyebrows given its safety implications. However, torque provides both efficiency and a gentler and more organized operation. And that one that cuts down repetitions concerning calls for maintenance.


Why You May Prefer Extension Springs?

Overall, torsion springs may come front and center stage. Yet extension springs still have their role to play. So, depending on your unique circumstances, extension springs might be the practical choice. They are budget-friendly and frequently find their home in residential settings.


Navigating the World of Garage Door Springs: Answers to Common Questions

The section below aims to explore the complications involved in garage door springs. We highlighted some popular queries regarding torsion and extension garage door springs.


Can I Replace the Garage Door Springs Myself?

Sure, it's technically possible to handle those springs yourself. Though, it's not recommended. These springs store a lot of energy. Can lift doors. However, the potential dangers of spring snapping during your DIY project are quite serious.

Incidents have resulted in loss of life due to mishandling these springs. No matter how skilled you are at DIY or how simple the task may seem, seeking help is crucial. Don’t take this risk alone; trust the experts for this repair job.


Are Springs Universally Compatible?

Picture yourself attempting to lift a heavy garage door using too small and light springs. It's bound to end in disappointment. Springs, like the doors they assist, come in sizes and strengths.

It's crucial to take an approach. Expert installers can match your door with the spring regardless of its make, model, or age. There's no one size fits all solution. Your garage door has requirements that call for customized solutions.


Rusty Springs: To Replace or Not to Replace?

Is rust a death sentence for your springs? Not necessarily. While rust can be a nemesis for metal components, including springs, it doesn't always mean the end.

The severity of the rust is what matters. If your springs have been regularly oiled and the rust results from wet weather, a professional inspection might be all that’s needed.

On your part, you can lubricate the spring to restore its functionality. However, if the rust has been persistent and has compromised the spring's integrity, consider replacing it. Ultimately, making this decision requires balancing your maintenance history with the extent of corrosion present.


Uneven Lifting: Springs or Something Else?

Picture your door lifting unevenly—could it be the springs? Especially if your door has two springs. A discrepancy likely means something snapped and defective, but tread with caution; it could also mean track issues. Loose tracks, obstructions, or even malfunctioning rollers could be at issue. You may need experts to decipher these issues.


Wrap Up

Some truths, however, shine brightly in the labyrinth of garage door springs: Safety always deserves a higher place than DIY ambitions; customization is supreme in spring selection; rust isn't always a death knell for springs; and uneven lifting hints at a symphony of possible culprits.
