Garage Door Springs

Shop replacement garage door springs for residential, commercial, and light-duty overhead garage doors. Garage door springs are the main counterbalance system that helps lift and support the weight of the door. When a spring is worn, broken, incorrectly sized, or installed in the wrong direction, the door can become heavy, uneven, unsafe, or unable to open properly.

Garage-DoorParts.com carries garage door spring options for common repair and replacement needs, including torsion springs, extension springs, right-wind torsion springs, left-wind torsion springs, coated torsion springs, and related spring hardware. Whether you are a garage door technician, contractor, property manager, maintenance professional, or an experienced DIY customer, choosing the correct spring size is critical for safe and proper door operation.

Garage Door Torsion Springs

Torsion springs are mounted above the garage door opening on a torsion tube. These springs twist and store mechanical energy as the door moves, helping balance the door’s weight. Most modern sectional garage doors use one or two torsion springs, depending on the door size, weight, and design.

When ordering a torsion spring, always confirm these specifications before purchasing:

Wire size
Inside diameter
Spring length
Wind direction: Right Wind or Left Wind
Overall door height and weight
Spring finish, such as coated or oil-tempered
Cone type and compatibility
Single-spring or two-spring system

A torsion spring that is too strong or too weak can cause the garage door to open too quickly, close too heavily, stop unevenly, or put extra strain on the opener. Matching the correct spring size is not just a convenience issue — it is a safety and performance issue.

Right Wind vs Left Wind Garage Door Springs

Garage door torsion springs are directional. A Right Wind spring and a Left Wind spring are not interchangeable. On a standard torsion spring system, the right-wind spring is usually installed on the left side of the center bracket, and the left-wind spring is usually installed on the right side of the center bracket when viewed from inside the garage looking out.

If your existing spring is broken, do not guess the wind direction based only on which side it was installed on. Confirm the coil direction carefully before ordering. Selecting the wrong wind direction can prevent the spring from winding correctly and can create a dangerous installation condition.

Garage Door Extension Springs

Extension springs are usually installed along the horizontal tracks on both sides of the garage door. These springs stretch and contract as the door opens and closes. Extension spring systems are common on many residential garage doors, especially older installations.

When replacing extension springs, it is important to match the spring rating to the door weight and height. Extension springs should also be used with proper safety cables. Safety cables help contain the spring if it breaks and reduce the risk of injury or property damage.

How to Choose the Correct Garage Door Spring

Before buying a replacement garage door spring, identify the spring type used on your door. Torsion springs and extension springs are not the same and are not installed the same way. Then measure the existing spring carefully and compare the specifications to the product listing.

For torsion springs, measure the wire size, inside diameter, and spring length. Confirm whether the spring is Right Wind or Left Wind. For extension springs, confirm the door height, door weight rating, spring length, and end type.

If the original spring is missing, damaged, or impossible to measure accurately, the safest method is to weigh the garage door and calculate the correct spring based on door size, weight, and track setup. Guessing can lead to an unbalanced door and premature failure of the opener, cables, drums, rollers, hinges, and other hardware.

Common Signs You Need a New Garage Door Spring

A broken or worn garage door spring can cause several noticeable problems:

The garage door feels extremely heavy
The door will not open fully
The opener runs but the door barely moves
The door opens a few inches and stops
The door closes too fast
The door looks crooked or uneven
There is a visible gap in the torsion spring coil
The spring is stretched, loose, or damaged
The door slams shut or will not stay open
The opener is straining more than usual

If your garage door opener is struggling to lift the door, the opener may not be the real problem. In many cases, the issue is an unbalanced door caused by a weak, broken, or incorrectly sized spring.

Professional Garage Door Spring Safety Warning

Garage door springs are under extreme tension. Torsion springs and extension springs can cause serious injury, property damage, or death if handled incorrectly. Do not attempt to remove, wind, unwind, cut, stretch, or adjust garage door springs unless you understand the correct tools, procedures, and safety precautions.

Garage-DoorParts.com sells replacement garage door springs and related hardware for customers who are qualified to identify, order, and install the correct parts. If you are not experienced with garage door spring systems, we strongly recommend hiring a professional garage door technician.

Related Garage Door Spring Parts

Many spring repairs also require inspection of related hardware. When replacing a garage door spring, check the condition of the cables, drums, bearings, center bearing plate, end bearing plates, torsion tube, bottom brackets, rollers, hinges, and track alignment. A new spring installed on worn or damaged hardware may not solve the full problem and can create additional safety risks.

Frequently Asked Questions

How do I know which garage door spring I need?

You need to identify the spring type first: torsion spring or extension spring. For torsion springs, confirm the wire size, inside diameter, length, wind direction, and finish. For extension springs, confirm the door height, door weight rating, spring length, and end type.

Can I replace only one garage door spring?

If your garage door uses two torsion springs or two extension springs, it is often recommended to replace both springs at the same time because they usually have similar cycle life and wear. Replacing only one spring can leave the door unevenly balanced if the other spring is old or weak.

What does Right Wind and Left Wind mean?

Right Wind and Left Wind describe the coil direction of a torsion spring. The wind direction determines how the spring is installed and wound. Right Wind and Left Wind springs are not interchangeable.

Why does my garage door opener struggle after a spring breaks?

A garage door opener is not designed to lift the full weight of the door by itself. The spring system balances the door. When a spring breaks or becomes weak, the opener may strain, stop, reverse, or fail to lift the door.

Are coated torsion springs better?

Coated torsion springs can offer cleaner handling and added surface protection compared with standard oil-tempered springs. The correct size, wind direction, and cycle rating are still more important than the finish alone.

Can I order a spring if I only know the door size?

Door size alone is usually not enough. Two garage doors with the same width and height can have different weights depending on material, insulation, windows, struts, and hardware. The safest way to choose a spring is by using accurate spring measurements or the actual door weight.

Need Help Choosing a Spring?

If you are not sure which spring you need, gather as much information as possible before ordering. Helpful details include the wire size, inside diameter, spring length, wind direction, door width, door height, door material, door weight, and photos of the existing spring system.
