Extension Springs are the baseline spring system that are supplied with Garage Doors. They are effective and cost-efficient, but tend to be much more dangerous and not as long lasting as torsion springs. Instead of being mounted on a tube shaft, these springs are operated on a drive cable and safety cable. The safety cable is meant to keep the spring in place when it breaks, but regardless, the breaking of an extension spring can cause damage versus a torsion spring. If when your door is up, and tension is off your extension spring and you can see spaces in between the coils, it is time for new extension springs or a conversion to torsion if applicable.

Torsion Springs are the safest, most reliable spring system that is available for garage door systems. Easy to maintain, and safer operation. When a torsion spring breaks, most of the time it will snap somewhere in the spring wire, but it will stay all on the tube shaft it is secured to. Torsion springs are an upgrade from extension springs. We recommend all customers who have the correct headroom, to switch their extension spring system to a torsion spring system.
