Torsion Springs vs. Extension Springs

Garage door springs, torsion and extension are crucial for door operation. Torsion springs, mounted horizontally, offer better balance, stability, and safety with longer lifespans and lower maintenance. On the sides, extension springs are budget-friendly but lack stability and may be hazardous if they break.

Choosing the correct type of springs is essential for ensuring the longevity and functionality of a garage door.

In this article, we will explore the two main types of garage door springs – torsion springs and extension springs and help you decide while considering factors like door weight, headroom, balance, safety, lifespan, maintenance, and professional installation.

Torsion Springs

Torsion Spring

Torsion springs mounted horizontally above the garage door provide better balance, stability, and safety during door movement.

Torsion springs last longer and need less maintenance than extension springs, making them cost-effective despite higher upfront costs and complex installation.

Extension Springs

Extension Springs

Extension springs on either side of the door parallel to the tracks are budget-friendly and ideal for lighter doors. They offer more straightforward DIY installation.

Extension springs have few drawbacks as less balance and stability during door movement than torsion springs, leading to potential misalignment over time. Their side location poses safety concerns, as they can snap back if they break, potentially causing harm.

Torsion Springs vs Extension Springs

Both types of springs have advantages and disadvantages, so understanding your specific needs and preferences will help you make the right decision. Here are the main characteristics to look out for.

Mounting Location

Torsion Springs are mounted horizontally above the garage door on a metal shaft.

Extension Springs are mounted on either side of the door, parallel to the horizontal track.

Space Requirements

Torsion Springs requires less vertical space, making them suitable for garages with limited headroom.

Extension Springs require more vertical space compared to torsion springs.

Balance and Stability

Torsion Springs provide better balance and stability during door movement, resulting in smoother operation.

Extension Springs offer less balance and stability, potentially leading to a less smooth door operation and misalignment over time.


Torsion Springs are considered safer because they are above the door, reducing the risk of accidents and injuries.

Extension Springs pose safety concerns as they are located on the sides and can snap back if they break, potentially causing harm.


Torsion Springs generally have a longer lifespan compared to extension springs.

Extension Springs have a shorter lifespan and may require more frequent replacement.


Torsion Springs require less maintenance, contributing to their cost-effectiveness in the long run.

Extension Springs need regular maintenance to ensure proper operation and safety.


Torsion Springs are more expensive than extension springs due to their design and installation complexity.

Extension Springs are more budget-friendly but may incur higher maintenance costs over time.

Weight Capacity

Torsion Springs are suitable for heavier garage doors due to their superior weight-handling capabilities.

Extension Springs are best suited for lighter garage doors.

Professional Installation

Torsion Springs installation is more complex and should be done by a professional to ensure safety and proper functioning.

Extension Springs are relatively easier to install, but professional installation is still recommended.


Choosing between torsion springs and extension springs requires careful consideration of several factors. Torsion springs offer better balance, stability, and safety with longer lifespans and lower maintenance needs. However, they come at a higher upfront cost and require professional installation.

On the other hand, extension springs are more budget-friendly but may lack stability and pose safety concerns. They are better suited for lighter doors and may require more frequent maintenance.

Ultimately, the decision depends on your garage door requirements, weight capacity, available space, safety priorities, and long-term cost considerations.
