Torsion vs. Extension Springs in Downey: Which Does Your Garage Door Need?
2026-05-30 7 min read
Here's what most homeowners don't realize about garage door springs: not all springs are created equal. Your garage door relies on either a torsion spring or an extension spring to lift 300 to 400 pounds safely every single day. Get the wrong type, and you're looking at a failed door, a safety hazard, or worse. I've seen garage doors come crashing down because someone tried a DIY replacement with the wrong spring configuration.
What Are Torsion Springs?
Torsion springs sit horizontally above your garage door opening, wound tightly like a clock spring. When your door closes, these springs store mechanical energy. When it opens, that energy unwinds, counterbalancing the door's weight so your opener doesn't have to work as hard.
Most modern homes in Downey use torsion springs. They're durable, precise, and last 7 to 9 years under normal use. A single torsion spring can support your entire door. If it snaps, the door won't open or close smoothly. Unlike extension springs, torsion springs fail less dramatically. You'll notice the door getting heavier to lift before catastrophic failure.
The tradeoff: torsion springs are more expensive to replace than extension springs. But they're worth it for safety and longevity.
What Are Extension Springs?
Extension springs run horizontally along both sides of your door opening, parallel to the tracks. They work like a rubber band: as your door lowers, the springs stretch. When your door rises, they contract and help lift the weight.
Extension springs are common in older Downey homes or budget installations. They're cheaper upfront. However, they have two major drawbacks. First, they wear faster than torsion springs, typically lasting 5 to 7 years. Second, when one snaps, the other side takes the full load instantly, which often causes it to snap within weeks.
That's where danger enters. A snapped extension spring can cause the door to fall unevenly, pinching cables or damaging the frame. Safety cables run alongside extension springs specifically to catch them if they fail, but those cables need maintenance too.
How to Tell Which Type You Have
Walk into your garage right now and look above the door. If you see a single coiled spring running horizontally across the center, you have a torsion spring. If you see two springs running along the left and right sides of the opening, you have extension springs.
Not sure? That's exactly when you should call a professional. Misidentifying your spring type can lead to ordering the wrong replacement, which wastes time and money.

The Safety Case for Torsion Springs
If you're planning a spring replacement, torsion is the safer choice. A torsion spring failure is usually gradual. You'll notice the door getting heavier or jerking slightly. An extension spring snapping feels like a gunshot. The door can slam down without warning.
I've attended to houses in Downey and surrounding areas where extension spring failures injured people. A child's hand. A pet. A car parked underneath. Torsion springs reduce that risk significantly because they fail more predictably and are contained above the door.
Modern building codes in California increasingly favor torsion systems for residential doors. If your home still has extension springs and you're thinking about replacement, read our guide on when to replace your garage door springs to understand the full cost picture.
Installation and Replacement Costs
Torsion spring replacement typically costs between 200 and 400 dollars in Downey, depending on the spring's size and your door's weight. Extension springs cost 150 to 300 dollars. But here's the catch: if you have extension springs and one snaps, you should replace both at the same time. That doubles the cost immediately.
Many homeowners try to save money by replacing only the broken spring. Within a few months, the surviving spring fails from the added stress. You end up paying twice.
Never attempt spring replacement yourself. These springs are under extreme tension. A slip means serious injury or death. Schedule a free quote with Garage Door Downey and let a trained technician handle it safely.
Which Should You Choose for a New Door?
If you're installing a new garage door or replacing an old one, choose torsion springs. The extra upfront cost pays for itself in safety, durability, and peace of mind. You'll get 7 to 9 years instead of 5 to 7, and you'll sleep better knowing your family is safer.
Your garage door opener works more efficiently with torsion springs too. Less strain on the motor means fewer repairs down the road. Check out our services page for spring replacement options to see what we recommend for your specific situation.
Don't Wait on a Failing Spring
A snapped or failing spring won't fix itself. Every time you use that door, you're putting stress on your cables, tracks, and opener. Costs compound quickly. If you've noticed your door feeling heavier, jerking, or making unusual noises, that's a warning sign.

Frequently Asked Questions
Can I replace just one torsion spring? No. If one torsion spring snaps, the other is likely near failure. Replace both at the same time to avoid imbalance and a second expensive repair within weeks.
How do I know if my extension spring is about to snap? Listen for squeaking or creaking. Watch for uneven door movement or the door sagging on one side. These are early warnings. Don't wait for the snap.
Are torsion springs worth the extra cost? Yes. They last longer, fail more predictably, and are safer. The 50 to 150 dollar difference per spring pays back through fewer repairs and peace of mind.
Can I upgrade from extension springs to torsion? Yes, but it requires professional installation. The mounting hardware and door frame may need adjustments. Get a same-day estimate from our team.
How often should I have my springs inspected? Every 6 to 12 months, especially if your door is over 5 years old. Early detection prevents emergency repairs and keeps your family safe.
