Garage Door Torsion Springs
Professional Series Springs --- ALL IN STOCK & READY TO SHIP
Torsion spring(s) for torsion systems set above the garage door. If there are multiple springs on your garage door we strongly recommend replacing BOTH torsion springs. Winding bars are 18" in length and are also advised when winding and un-winding springs. We we offer a vast selection of wire and spring sizes and both left and right wind torsion springs. All springs come with a free nylon center bushing.
* "High-Cycle" is a upgrade to the measurements entered above to a higher cycle, longer lasting springs.
Please read: For most garage door torsion systems: Left Wound (Black Cone) = Right side / Right Wound (Red Cone) = Left Side.
Torsion spring coated and oil tempered and include cones installed. Springs are factory coated for smoother, cleaner operation. For use on garage doors with standard lift drums. Minimum 10,000 cycles, Springs are made of steel coils with aluminum cones.

How to Measure Torsion Springs
WARNING: Torsion springs, extension springs, and other garage door hardware can cause serious injury or death if not handled and installed properly. Professional installation is recommended. Do NOT attempt to install springs or hardware yourself unless you have the proper tools, reasonable mechanical aptitude and experience, and upper arm strength. Read and understand all instructions before you begin work. Extension and torsion springs, along with attached hardware, are under extreme tension at all times. All tension must be released from springs before any work is performed.
This method of measuring your torsion spring requires you to measure the existing springs. Use this method if the door worked correctly before the spring(s) broke and the garage door has not been tampered with. To measure the torsion springs, follow each of the following steps carefully. If the garage door has two springs measure each spring individually. It is not uncommon to have two different size springs. If you prefer a matching set, we can convert a mismatched set to a matching set.
Step 1 Determine Wire Size
The most efficient way to measure the wire size is to measure 10 coils and then measure 20 coils and compare the measurements to the chart below. Measure to the nearest 1/16" of an inch. It is important to make sure there are no gaps between the coils and that the spring(s) is not wound. Measuring coils that have gaps or a wound spring will give incorrect measurements.
Step 2 Determine Springs ID (Inside Diameter)
For your broken spring(s) measure the inside diameter of the spring. If the spring is in one piece you can find the diameter on the cones, p175=1 3/4" and p200=2". Typically residential springs will have a 1 3/4" or 2" inside diameter.
Step 3 Determine Spring Length
When measuring your torsion spring, remember that in order to get a proper measurement the spring must be un-wound. If the spring is in two parts, unscrew set screws and connect spring ends together to get a total measurement. Do not include the cones in the measurement.

Step 4 Determine Spring Wind
Most standard residential torsion systems have two torsion springs, one on the right and left. The Left spring is right hand wound(RHW), and the right spring is left hand wound(LHW). If one spring is broken on your torsion system, we highly recommend replacing both springs.
