Which Springs Will Fit My Garage Door? 

Understanding what types of garage door springs compatible with your door is crucial to comprehend the color code utilized for identifying its distinctive features. Selecting the wrong type and size of spring can cause problems with opening and closing the garage door, in addition to causing long-term wear and tear on its components.

Both torsion springs and extension springs use color-coded options when it comes to sizes, materials, and load ratings. This is because there are two different types of springs, each requiring different specifications to fit properly.

  • Torsion Springs are wound in a coil shape and store energy as it is released when the garage door opens or closes. 
  • Extension springs, on the other hand, stretch and retract as the door moves up and down.

Hence, understanding their differences is essential in making sure your garage door runs smoothly every time.

Torsion Springs

Torsion springs are garage door springs that can be spotted above the door and look like large steel rods in two separate coils. They often have larger bends on each end. When broken, they split into two separate pieces, which makes them quite visible and easy to identify.

These springs are within an assembly inside the header, typically centered above the garage door. They use torque to increase lift power, pressing against drums that rotate when operated.

A garage door torsion spring chart can be used to determine the sizes and characteristics of those springs. The chart is color-coded to indicate the wire size, type of material, outside diameter (OD), inner diameter (ID), active coils, and various other factors.

For example, a torsion spring in orange may indicate an 18” length with a 2.25” inside diameter and 1.25” wire thickness. A blue torsion spring may indicate a 22” length with a 2.5” inside diameter and 0.243” wire thickness.

It is important to remember that not all manufacturers use the same color code. Therefore, it is best to double-check the door manually or call the manufacturer before buying and fitting new springs.

Torsion springs are favorable over other springs due to their increased lift capacity. They have improved dynamic performance in rough conditions, as they absorb grinding shocks and vibration better. As such, torsion springs provide reliable use for longer than other garage doors.

Extension Springs

Extension springs are a type of spring commonly used in garages and can be identified easily due to their distinctive look. They resemble a coil and have hooks on either end.

They are typically found along the length of the garage door and connected with pulleys. They work when a system tension is released, which contracts the spring resulting from an extension of those coils, creating energy.

You can use a garage door extension spring size chart to determine the characteristics of the springs. Extension springs use a color code system similar to torsion springs, though they may differ from manufacturer to manufacturer.

For instance, an extension spring in black may indicate a 19” length with two coils and 0.1875” wire thickness.

Compared to other types of springs, extension springs offer multiple advantages, such as being cost-effective and providing more power, allowing heavier objects to be lifted.

Additionally, they offer greater safety since they have fewer rotating parts than torsion springs, thus preventing accidents related to excessive tension on cables.

Knowing how to recognize this type of spring will help ensure your garage door works properly.

Yellow-colored springs typically hold doors up to 125 pounds, while blue-colored ones are designed for a slightly heavier door weight of up to 150 pounds.

Additionally, red-colored springs support even bigger, heavier doors weighing up to 175 pounds.
