Replacement Torsion Springs for Self Storage Roll-Up Doors
Door Springs for Roll-Up, Overhead & Garage Doors

Torsion springs are essential for the smooth, efficient operation of roll-up, overhead, and garage doors. These heavy-duty springs store energy as they’re wound when the door closes, then release that energy as they unwind during opening. This counterbalances the door’s weight, allowing it to lift and lower with minimal effort. Without a torsion spring, the door becomes dead weight and can’t operate safely or efficiently.
A correctly sized and calibrated torsion spring improves performance, reduces strain on openers, and helps prevent premature wear on other components. Choosing high-quality replacement door springs ensures long-term reliability, smoother daily operation, and enhanced safety for both commercial and residential applications.
Note: Each spring is custom made to order. No returns, exchanges, or refunds. Report any order discrepancies within 15 days of delivery; minor length variations of ±1 coil width are normal.
›How to Measure a Replacement Spring
Overview: How to Find the Right Spring Size for a Self Storage Roll-Up Door
When ordering torsion springs, there are four specific items you will need to know in order to get the correct replacement spring:
- Wire Size
- Inside Diameter of the spring
- Length of the spring
- Wind of the spring (right or left wound)
How to Measure the Wire Size of a Torsion Spring
The best way to determine the wire size of your spring is to measure the length of ten or twenty coils to the nearest one-sixteenth of an inch, and refer to the Spring Wire Chart.
How to Measure the Inner Diameter of a Torsion Spring
The inside diameter is the distance across the inside of the spring. Measure the inside diameter to the nearest one-sixteenth of an inch.
How to Find the Length of a Spring
The spring must be tightly compressed with no gaps. If distorted or broken, lay the pieces together to get the overall length, or count the total number of coils and multiply by the wire size. The final size of the spring you receive may vary by plus or minus one coil width.
How to Determine the Wind Direction
Spring wind refers to the direction the spring’s wire is coiled. It determines how the spring unwinds as the door moves. If the incorrect wind type is installed, the door will not function properly.
Look at the end of the spring with the hooks, as shown in the image. Does it rotate to the right or left as it winds away from you? Right-hand springs wind clockwise. Left-hand springs wind counterclockwise.
How to Determine the Spring End Type
Compare your spring ends to the images on this page to determine the end type.
