Torsion springs are tightly wound coils of steel, positioned horizontally above the garage door frame. Their core purpose is to counterbalance the full weight of the door, making it possible to lift or lower large, heavy doors with minimal effort. When the door opens, the torsion spring unwinds, releasing stored energy to help raise the panel smoothly. As the door closes, the spring winds back up, preparing for the next lift.
Mechanics and Key Components
A typical system uses one or two torsion springs mounted on a shaft. The ends of the shaft are supported by sturdy bearings, while cable drums sit at both sides. High-tension steel cables attach to the bottom of the door and wrap around these drums. As the garage door moves, the springs' tension is distributed through the shaft and cables, allowing the panels to travel effortlessly. Correct adjustment is key for balance and safety.
Understanding Spring Life Cycle and Influencing Factors
Most residential torsion springs are rated for 10,000 to 15,000 cycles—each cycle being one full open and close—translating to a service life of 5 to 7 years under average conditions. Some premium models exceed 30,000 cycles. Added door weight from extra insulation, windows, or decorative hardware may stress springs and shorten their expected lifespan. Regular checkups and avoiding excess modifications will help your springs last longer.
Safety, Maintenance, and When to Call a Professional
Due to the high tension and risk involved, torsion spring repair and adjustment is never DIY—special tools and training are required to prevent injury or property damage. Warning signs of wear include loud noises, jerky movement, uneven door positions, or visible gaps in the spring coil. Routine maintenance done by licensed pros ensures reliable performance and protects your investment.
