Traditional garage doors operate using either torsion springs or extension springs. While both support the overall function, safety, and efficiency of your door, they each provide unique differences and benefits that set them apart. Learn more about garage door springs and the best option for you using the guide below.

Torsion Springs

Torsion springs are mounted horizontally above the opening of your garage door. Depending on your garage, either one or two springs work together with the shaft and drums to form an assembly known as the counterbalance. This counteracts the force of balance on the door, making it easier to lift.

These springs are durable, maintaining an average lifespan of five to seven years, or around 10,000 open and close cycles. However, torsion springs may be susceptible to rust and cold weather.

Over time, the spring will gradually weaken and become less effective, indicating the need to be replaced. When a torsion spring breaks, it makes a loud sound but is not typically dangerous. Replacing or repairing the spring should be completed by a professional.

Extension Springs

Extension springs sit just above the upper tracks on both sides of your garage door.

Like torsion springs, they help to open and close the door as the springs expand and contract. Extension springs are manufactured specifically for the height of a garage door using a relaxed and compressed length to determine how far the spring should be stretched when the door is closed.

While extension springs are typically less expensive than torsion springs, they require more parts and can be prone to damage. Like tension springs, extension springs are also certified to last up to 10,000 lift-and-close cycles, maintaining an average lifespan of seven years depending on use.

Extension springs can be dangerous when they break, potentially launching into the air and causing damage or injury. Repairs or replacements should only be done by an experienced repairman.
