Garage door springs do the heavy lifting every time your door opens, and there are two main types: torsion and extension. Knowing which one your door uses helps you understand how your system works and what to expect when it is time for a repair. Here is a simple breakdown.
Torsion Springs
Torsion springs mount on a metal shaft above the door opening. When the door moves, they wind and unwind, using twisting force to lift the weight. They tend to operate more smoothly, last longer, and handle heavier doors better, which is why most newer doors use them. Because they carry a lot of stored energy, they are also higher rated by cycles.
Extension Springs
Extension springs run along the horizontal tracks on each side of the door and stretch and contract as the door moves. They are common on older systems and single doors, and they usually cost a little less up front. Because they are under tension along their full length, safety cables are important to keep a broken spring from becoming a hazard.
Which One Is Better?
For most homes, torsion springs are the better long-term choice thanks to smoother operation and a longer lifespan. That said, the right option depends on your door size, weight, and setup. A technician can tell you exactly which type you have and recommend the best replacement for your specific door.
Why Spring Work Is Never a DIY Job
Both spring types are under extreme tension, and a spring that releases unexpectedly can cause serious injury. That is why spring replacement should always be handled by a trained technician with the right tools. Keeping the springs lubricated during regular garage door maintenance helps them last, but replacement itself is not a do-it-yourself project.
