Torsion vs Extension Springs: Everything You Need to Know
2024-01-08 7 min read David Garcia
Garage door springs are the unsung heroes of your garage door system. These heavy-duty components do the actual work of lifting your garage door, which can weigh anywhere from 150 to 400 pounds or more. Understanding the different types of springs and how they work will help you maintain your garage door and recognize when professional service is needed.
The Two Types of Garage Door Springs
Torsion Springs
Torsion springs are mounted horizontally above the garage door opening on a metal shaft. When the door closes, the springs wind up and store energy. When you open the door, this stored energy is released, helping to lift the heavy door with minimal effort from the opener.
Advantages of Torsion Springs: - Longer lifespan (15,000 to 20,000 cycles vs. 10,000 for extension springs) - Smoother, more controlled door operation, Less wear on other door components, Safer design with contained energy release, Better balance and less strain on the opener
Considerations: - Higher initial cost, More complex installation requiring professional expertise, Require more headroom above the door
Extension Springs
Extension springs are mounted on either side of the door, running parallel to the horizontal tracks. These springs stretch and contract as the door opens and closes, providing the counterbalance force needed to lift the door.
Advantages of Extension Springs: - Lower initial cost, Easier to install in spaces with limited headroom, Individual spring replacement possible
Considerations: - Shorter lifespan, Can be dangerous if they break without safety cables, Less smooth operation, More wear on other door components
Signs Your Springs Need Replacement
Recognizing the warning signs of failing springs can prevent sudden breakage and potential safety hazards:
Visual Signs: - Gaps in the spring coils (torsion springs) - Stretched or elongated appearance (extension springs) - Rust or corrosion, Visible wear or fraying
Operational Signs: - Door feels heavier than usual when lifting manually, Door doesn't stay open or closed, Loud bang or snapping sound (indicates spring has already broken) - Door opens unevenly or crooked, Opener struggles or strains to lift the door
The Dangers of DIY Spring Replacement
We cannot stress this enough: garage door spring replacement is not a DIY project. These springs are under extreme tension and can cause serious injury or death if mishandled. Every year, thousands of people are injured attempting to repair or replace garage door springs themselves.
Torsion springs, in particular, store an enormous amount of energy. A spring that suddenly unwinds can cause the winding bar to strike with tremendous force. Extension springs without safety cables can become dangerous projectiles if they break.
