Torsion vs. Extension Springs: Which Is Right for You?

If your garage door isn’t opening smoothly, or has stopped working altogether, it could be time to inspect the springs. When it comes to residential garage doors, torsion and extension springs are the two most common types used. But how do they work, and which is right for you?

Read on to explore the key differences between these spring types, how they affect door performance, and which option may suit your home best.

What Do Garage Door Springs Actually Do?

Garage doors are heavy. Even B&D’s lightweight models are designed with premium materials that can weigh 100 kilograms or more. The spring system is what makes manual lifting possible and allows your opener to do the hard work with minimal effort.

Springs store mechanical energy as tension, helping balance the door’s weight. If they’re not properly chosen or maintained, your garage door could become noisy, slow, or dangerous to operate.

What Are Torsion and Extension Springs?

Torsion springs

Torsion springs sit horizontally above the garage door opening. As the door closes, the spring coils tighter, storing energy. When you open the door, the spring unwinds, releasing that energy to lift the door.

 

Extension springs

Extension springs stretch and contract along the tracks on each side of the door. They expand when the door closes and contract as it opens.

Comparing Performance and Lifespan

Torsion springs are generally more durable and last longer than extension springs. They distribute weight more evenly and operate with fewer moving parts, reducing wear.

Feature Torsion Springs Extension Springs
Lifespan 15,000–20,000 cycles 5,000–10,000 cycles
Operation Smooth and balanced Can be jerky
Maintenance Less frequent More frequent
Safety Safer with fewer risks Requires safety cables

Which Is Right for You?

If you’re installing a new garage door or upgrading an old one, torsion and extension springs offer different advantages. Here’s a breakdown to help you decide.

In most modern installations, especially those handled by an accredited B&D dealer, torsion springs are the recommended standard due to their reliability and long-term value.

Are B&D Garage Doors Compatible with Both?

Most B&D garage doors are engineered for torsion spring systems. Products like the Panelift® Icon™ and Roll-A-Door® Series 2 are designed to deliver smooth lifting motion, quiet operation, and enhanced control, making torsion springs a natural fit.

In rare cases where extension springs are still in use (usually older roller doors), B&D dealers can assess whether a spring upgrade is possible or recommend a full replacement with a compatible torsion-based setup.

For all new installations, B&D only supplies garage door systems using torsion springs for maximum performance and safety.
