Over time, your overhead doors may require a spring replacement. Swapping out the old part for a new one will require ascertaining whether the door features extension or torsion springs. Here are four main differences between the styles that you should know.

4 Critical Differences Between Torsion & Extension Springs

1. Number of Parts

Torsion springs require only cables and springs to operate the garage door. Extension springs use much longer cables and sheaves that attach to the door track and help guide the door. With more parts, this model is more likely to have mechanical difficulties and requires more maintenance. It’s essential to tighten up the hardware on the sheaves regularly and to lubricate everything to keep the structure functioning properly.

2. Lifetime

Most homeowners have to have a technician replace the springs in their overhead door every seven to nine years if they regularly open and close it around four times per day. Torsion springs may last up to 20,000 cycles, which is around twice as long as extension options because they undergo less wear and tear. Torsion springs stretch less, and unlike extension springs, it can minimize the impact of each movement.

3. Motion

Extension springs can be jerky as the spring pulls the door open. Torsion springs are denser and store more energy, which allows them to have better control of the door and create a smooth opening and closing motion. 

4. Safety

Many overhead door spring replacement technicians prefer torsion springs because they are less likely to fly through the garage. Extension springs can break apart, sending pieces smashing into your vehicle and potentially injuring someone. Torsion springs stay on the shaft, and while you may hear a loud noise as they break, they won’t turn into a projectile.
