The Garage Door Springs Anatomy

The garage door springs for a standard overhead door are located on the shaft, above the garage door. The standard garage door torsion springs have winding cone in one end and a stationary cone at Garage-Door-Spring-Winding-Conethe other. The winding cone is being used when installing and adjusting the springs, as the stationary cone secures the springs to the spring anchor bracket (center bracket). While the spring’s coil connecting between the winding cone and the stationary cone, the winding cone gets wound up to create the necessary torque level.

The Shaft System

The shaft is the hollow metal tube that crosses the garage door lengthwise. It is being held by the spring anchor bracket and by the end bearing plates; its purpose is to shift the springs’ torque level to the lift cable drums. The cables that wrapping around the drums going down to the door’s lowest section and attaching to the end bottom brackets on both ends.


With the right springs you can the easily operate the garage door manually up and down. When the garage door is in down position, the cables hold the garage door’s weight while the torque level remains as is and the garage door springs staying wound up. When the garage door goes up, the cables are wrapping around the lift cables drums, allowing the springs to become unwound. Since the horizontal tracks holding the upper section of the garage door’s weight, the garage door springs do not need substantial amount of torque to keep the garage door in up position.


Garage Door Spring that designed to lift 120 pound, installed on 200 pound garage door, will cause it to be heavy to operate. On the other hand, garage door spring that designed to lift 200 pound, installed on 120 pound garage door, will cause it to pull up. In both cases, wrong springs will cause to an early wear out of the garage door components, of the garage door opener mechanisms and can easily cause the garage door to go off its tracks.

Many Hands make Light Work

A single, large garage door spring will definitely hold the garage door’s weight and will keep it balanced; the problem with one garage door spring installed is that with lack of counter force on the other side of the spring anchor bracket, a single spring will pull the shaft to the side when the garage door is going up and down.

A single garage door spring will cause severe damage to the garage door system components, including early wear out of the cables, bearings, brackets, door’s sections and hinges.”

This situation is a major safety issue as well; by pulling the shaft to the side, the spring anchor brackets’ bolts can get loose over time. Furthermore, pulling the shaft sideways can damage the end bearing plate’s bearing and to cause system misalignment and unwanted pressure on the shaft, what will eventually bring the shaft to shear off.

Replace Broken Spring Only?

The vast majority of garage doors systems have two torsion springs or more installed on them. When the garage door goes up and down, each spring goes one cycle. Since all of the garage door springs accumulate the same amount of cycles over time, when one spring breaks, the others will break soon. As you go through the process of replacing one broken spring, replacing the others will save you valuable time, trouble and money. Therefore, once spring breaks, the recommendation is always to replace all other garage door springs.

Garage Door Springs Measurements

There’s a lot to consider when measuring a garage door spring. The standard torsion spring has five main properties:

  • Length
  • Wire Type
  • Inner Diameter
  • Wind Side
  • Ends’ Type


Each property must to be carefully examined.

As garage door experts, we must have the knowledge and the expertise to determine what type of torsion spring the garage door system needs.”

In most cases, the garage door spring type can be determined by designated equipment. However, in some cases, the spring’s coil can get deformed overtime. In this case, we required to recompute corresponding system’s attributes, such as: the garage door’s weight and size, the garage door track’s radius and the lift cable drum’s radius, all must be taken into account.
