SSC .2437 x 1.75" ID x 35.25" Torsion Spring – Left Wind (LW) – Green

🇺🇸 Made in USA

This Left Wind (LW) torsion spring is manufactured by Service Spring Corporation (SSC) for sectional overhead door torsion systems requiring a .2437" wire size, 1.75" inside diameter, and 35.25" spring length.

Manufactured from coated, oil-tempered spring wire, this spring comes with the winding cone and stationary cone installed and is rated for an industry-standard minimum lifecycle of 10,000 cycles.

The .2437" wire size uses the Green color code. Color should be used only as an identification aid—always verify the actual wire diameter, inside diameter, spring length, and wind direction before ordering.

Specifications

Application

Designed for torsion-spring counterbalance systems where the calculated requirements call for a Left Wind .2437" x 1.75" ID x 35.25" torsion spring.

This spring may be used in residential or light-commercial sectional door systems when its torque characteristics correctly match the door weight, height, cable drums, track configuration, and overall counterbalance requirements.

Compatibility & Fitment

Torsion springs are not universal replacement parts.

Correct replacement requires matching or properly calculating:

• Wire diameter

• Inside diameter

• Spring length

• Wind direction

• Door weight

• Door height

• Cable drum type

• Track configuration

• Number of springs

• Required torque / IPPT

• Available shaft and spring space

Two torsion springs that look almost identical can have substantially different torque characteristics.

Left-Wind Identification

This is a Left Wind (LW) torsion spring.

On a conventional torsion setup, a left-wound spring is typically installed on the right side of the center support when viewed from inside the garage looking toward the door.

System configurations can vary, so always verify the actual spring winding direction rather than relying only on its installed position.

Green Wire Color Code

The Green color code identifies the .2437" wire size.

Do not select a replacement spring based on color alone. Paint markings can fade, become dirty, or be confused with other markings.

For accurate identification, physically verify:

• .2437" wire size

• 1.75" inside diameter

• 35.25" unwound spring length

• Left Wind direction

Important Matching Notes

When replacing one spring in a two-spring system, inspect and identify the opposite spring as well.

Paired torsion springs typically use opposite wind directions, but the two springs are not necessarily identical in every application.

Changing the wire diameter, inside diameter, or spring length changes the spring's torque and cycle characteristics. Alternative spring sizes should only be used after the counterbalance requirements have been properly calculated.

Cones Installed

This spring comes with both the winding cone and stationary cone already installed.

Proper torsion-spring installation requires correctly sized winding bars and knowledge of:

• Spring winding

• Shaft positioning

• Cable drum setup

• Cable tension

• Bearing alignment

• Door balancing

After installation, verify that the lift cables remain correctly seated on the drums and that the door is properly balanced throughout its travel.

Ready to Order?

If your existing spring matches the .2437" wire size, 1.75" inside diameter, 35.25" length, and Left Wind configuration, this SSC replacement spring is ready for your repair.

Add this spring to your cart today and restore proper counterbalance with the correct SSC-made replacement.

Before purchasing, double-check:

• .2437" wire size

• 1.75" inside diameter

• 35.25" spring length

• Left Wind (LW)

If any specification differs from your existing spring, verify the correct replacement before ordering.

Safety Warning

⚠️ Torsion springs operate under extreme stored mechanical energy and can cause severe injury, death, or property damage if improperly installed, adjusted, or removed.

Installation and service should be performed only by a qualified person familiar with torsion-spring systems and using proper tools and procedures.

Never loosen a winding cone, stationary cone, cable drum, bearing plate, or related torsion-system component while the spring is under tension unless you understand the correct service procedure.
