Torsion Springs
Torsion springs are mounted on a metal shaft above the garage door opening. They use torque (twisting force) to lift the door. Most modern residential garage doors use torsion springs because they provide smoother, more controlled operation.
Torsion springs are the most common type of spring used in modern residential garage doors. They are mounted horizontally on a steel shaft directly above the door opening, inside the garage.
When the door closes, the springs wind up and store energy. When you open the door, that stored energy unwinds and helps lift the door — which can weigh 150 to 400+ pounds depending on the size and material.
Why size matters: Every garage door has a specific weight, height, and track configuration. The springs must be precisely matched to these measurements. A spring that is too weak will not fully support the door, causing the opener to work harder and wear out faster. A spring that is too strong can make the door fly open uncontrollably.
Why professional installation is essential: Torsion springs are under extreme tension. A standard residential torsion spring stores enough energy to cause severe injury or death if it breaks or is improperly handled. Spring replacement should only be performed by trained, licensed professionals with the proper tools.
When you might need two springs: Many single-car garage doors use one torsion spring, while most double-car doors use two springs working together. Some homeowners upgrade single-spring setups to dual-spring systems — if one spring breaks, the other spring helps prevent the door from slamming down uncontrollably.
Key Characteristics
- Mounted horizontally above the door opening
- Uses twisting (torque) force to counterbalance the door
- Smoother, more controlled operation than extension springs
- Available in standard and high-cycle ratings
- Must be precisely sized for each door
When to Choose Torsion Springs
- Most modern residential garage door installations
- When you want smoother, quieter operation
- When upgrading from an extension spring system
- Two-car garage doors (dual spring setup recommended)
Safety Warnings
- • Torsion springs are under extreme tension — never attempt DIY replacement
- • A breaking spring can release with explosive force
- • Improper sizing can damage the opener motor or cause the door to fall
- • Always hire a licensed professional for spring work
