Torsion Spring
Torsion Spring
vs
Extension Spring
If your garage door spring has broken and needs replacement, you may have a choice between torsion and extension springs — or you may want to upgrade from extension to torsion. Here's how the two types compare.
| Feature | Torsion Spring | Extension Spring |
|---|---|---|
| Location | Mounted on a shaft above the door opening | Mounted along the horizontal tracks on both sides of the door |
| Safety | Safer — spring is contained on the shaft if it breaks | Less safe — can fly across the garage if it breaks (safety cables mitigate this) |
| Lifespan | Longer — 15,000–25,000+ cycles standard | Shorter — 10,000 cycles standard |
| Balance | Better — provides even, balanced lifting force | Uneven — springs wear at different rates, causing imbalanced operation |
| Noise | Quieter — smooth, controlled operation | Louder — stretching and contracting creates more noise |
| Price | $150–$350 per pair installed | $100–$200 per pair installed |
| Opener Wear | Less — balanced force is easier on the opener motor | More — uneven tension puts extra strain on the opener |
🏆 The Verdict
Torsion springs are the clear winner in every category except price. They are safer, last longer, operate more quietly, and are gentler on your opener. If you currently have extension springs, we strongly recommend upgrading to torsion springs during your next replacement — the conversion is straightforward and well worth the investment.
Comparison FAQ
Frequently Asked Questions
Can I convert from extension springs to torsion springs?
Yes. Converting from extension to torsion springs is a common upgrade that our technicians perform regularly. The conversion requires installing a torsion bar, spring(s), cable drums, and new cables. The existing extension spring hardware is removed. The entire conversion typically takes 2–3 hours.
How do I know which type I have?
Look above your garage door opening. If you see a horizontal shaft (metal bar) with one or two tightly coiled springs wound around it, you have torsion springs. If you see long springs stretching along the horizontal tracks on either side of the door (parallel to the ceiling), you have extension springs.
