Garage doors use either extension springs (one either side of the track, often used on lighter doors), or torsion springs (typically one or two along the wall above the door opening for heavier doors).

Extension Spring

Torsion Spring

A well-designed spring system counterbalances your garage door. The correct spring system required for safe and consistent equilibrium of your garage door is predetermined by our engineers and shipped with your door.


Steelead spring systems are considered among the best in the industry. Here are some things to consider when comparing the safety of garage door springing systems.

We strongly recommend that only a trained garage door professional install standard torsion springs. Standard extension springs can also be tricky.


Steelead extension springs come with a safety containment cable system that spans the entire length of the spring and prevents loose ends from causing damage or injury. If your garage doors have extension springs, be sure they utilize a safety containment cable.

Torsion springs are mounted on a shaft that acts as a containment system for that specific type of spring system.


Many injuries occur when unqualified do-it-yourselfers attempt to remove or adjust the bottom bracket that connects the lifting cables to the spring system. This bracket is under extreme pressure.  If it becomes loose, it can separate from the garage door’s overall structure and cause injuries or property damage. T-Bracket™ cannot be removed under normal circumstances until after the spring tension has been released.


Steelead uses normal black spring and corrosion resistant galvanized torsion springs on its standard size residential doors. Simply put, they are more attractive and last longer than oil tempered springs.


Standard Extension Springs

These are coiled springs installed above the door’s horizontal track. Experienced do-it-yourselfer’s can install these springs by closely following the installation instructions and safety warnings included with each Steelead garage door.

Standard Torsion Springs

These include a shaft, spring and drum assembly installed directly above the door opening. The torsion spring distributes the garage door’s weight evenly, which is critical with a wide and/or extremely heavy door. Standard torsion springs should only be installed and removed by a trained garage door professional.
