Garage door springs are the muscle behind your door’s operation. Understanding the two main types can help you make informed decisions about repairs and replacements.
Torsion Springs
Torsion springs are mounted horizontally above the door opening. They work by twisting and storing energy as the door closes, then releasing it to help lift the door.
Advantages:
- Longer lifespan (15,000-20,000 cycles)
- Smoother operation
- Safer when they break
- Better for heavier doors
Extension Springs
Extension springs run along the horizontal tracks on either side of the door. They stretch and contract to provide lifting power.
Advantages:
- Less expensive to install
- Simpler design
- Good for lighter doors
- Easier to find parts
Which Is Better?
Torsion springs are generally superior for residential doors. They last longer, operate more smoothly, and are safer. However, extension springs work well for lighter doors and are more budget-friendly.
Safety Warning
Spring replacement is dangerous and should only be performed by trained professionals. Springs are under extreme tension and can cause serious injury if mishandled.
