There are two types of springs used on traditional garage doors, torsion and extension. While both support the function, safety, and efficiency of your door's lift system, they each have unique characteristics that set them apart. Learn more about these spring types in the guide below. 

Torsion Springs

Metal torsion springs are mounted horizontally above the garage door and use torque to lift its weight. Depending on your system, your door may use one or two springs.

Typically, a single door uses one spring, while a double-wide door, or a heavy door, requires two. Torsion springs are highly durable, with an average lifespan of five to seven years, depending on use. Extended-life torsion springs may double their life expectancy.

While strong, their metal body can be susceptible to rust and cold weather, potentially weakening its structure over time. Without proper care and maintenance, torsion springs will gradually weaken and become less effective, requiring replacement. Unlike extension springs, torsion springs are not typically dangerous when they break. 

Extension Springs

Extension springs sit above the upper tracks on either side of your garage door. They operate as a traditional spring, expanding and contracting with the movement of your door.

Unlike torsion springs, extension springs are manufactured specifically for the height of your door, using the relaxed and compressed length to determine the size of the spring. While extension springs are often less expensive than torsion, they require additional components, such as hardware and safety cables.

While these parts provide security and stability, they can be prone to damages, potentially costing more in repairs over time. Like tension springs, extension varieties have a five to seven-year life span or 10,000 life-and-close cycles with care and maintenance.

Extension springs have more exposed mechanical components than torsion, potentially making them dangerous. When they break, they can detach and catapult into the air, potentially causing damage or injury. 

Whether your garage door uses torsion or extension springs, replacing them yourself can be dangerous and should always be done by a professional.
