Understanding Torsion vs. Extension Springs in Garage Doors

Garage doors use two main types of springs: torsion and extension. Understanding the difference can help homeowners know which type their garage door uses and what maintenance is necessary.

Torsion springs are mounted horizontally above the garage door opening. They work by twisting and storing energy, allowing them to control the door’s movement smoothly. Torsion springs are generally more durable and last longer than extension springs.

Extension springs run parallel to the garage door tracks. They expand and contract as the door moves, which can cause more wear over time compared to torsion springs. Extension springs are often found in smaller or older garage doors.

Both types are reliable, but torsion springs are typically more robust and require less frequent replacement. If you’re unsure which type your garage door uses, Pacific Experts can inspect your setup and recommend the best maintenance practices.
