SSC Right-Wind Garage Door Torsion Spring – .2343 Wire × 1.75-Inch ID × 29-Inch Length, Coated with Cones

Product Description

This right-wind garage door torsion spring is manufactured by Service Spring Corporation (SSC) from .2343-inch coated oil-tempered spring wire. It has a 1.75-inch inside diameter and a 29-inch unwound coil length.

The spring comes with professionally installed winding and stationary cones, making it ready for installation on a compatible residential sectional garage door torsion system.

As part of the garage door counterbalance system, the spring stores and releases torque to offset the weight of the door. Correct spring selection is essential for proper balance, smooth operation, and reduced strain on the garage door opener, cables, drums, bearings, and related hardware.

This is an industry-standard-cycle torsion spring rated for a minimum of approximately 10,000 operating cycles when correctly selected, installed, and used on a properly balanced garage door.

Common Uses

This SSC torsion spring may be used as a replacement on compatible sectional garage doors equipped with a torsion-spring counterbalance system.

Common applications may include:

• Residential steel sectional garage doors
• Insulated sectional garage doors
• Wood-overlay sectional garage doors
• Single-spring torsion systems
• Two-spring torsion systems
• Standard-lift garage door systems
• Compatible assemblies requiring a 1.75-inch-ID torsion spring

This spring must not be selected by garage door width, height, material, or appearance alone. The spring dimensions, required torque, door weight, cable drums, track configuration, and complete counterbalance system must be confirmed before ordering.

Compatibility & Fitment

This spring is compatible only when the required replacement specifications match:

• .2343-inch wire size
• 1.75-inch inside diameter
• 29-inch unwound coil length
• Right-wind direction
• Required spring torque
• Compatible winding and stationary cone arrangement
• Compatible torsion shaft and center-bearing configuration

A right-wind torsion spring is normally installed on the left side of a standard torsion assembly when viewed from inside the garage looking toward the door.

However, rear-torsion, reverse-wound, high-lift, vertical-lift, duplex, triplex, and other specialized systems may use a different arrangement. Always confirm the spring’s actual wind direction instead of relying only on its installed position.

The stated 29-inch length refers only to the unwound spring coils. Do not include the winding cone or stationary cone when measuring the original spring.

Important Matching Notes

Garage door torsion springs that appear nearly identical can produce substantially different amounts of torque.

Before ordering, verify all four primary spring measurements:

1. Wire diameter
2. Inside diameter
3. Unwound coil length
4. Wind direction

Also confirm:

• Required torque or IPPT
• Total garage door weight
• Garage door height
• Number of springs
• Cable-drum model
• Track configuration
• Torsion-shaft diameter
• Spring mounting arrangement
• Required number of winding turns

Do not select a replacement spring based only on:

• Painted spring or cone colors
• Garage door width and height
• Overall appearance
• The side where the spring is installed
• Another door with similar dimensions
• A measurement that includes the cones
• A stretched measurement across the broken-spring gap

When measuring a broken spring, measure the intact coil sections and add those measurements together. Do not include the open gap created by the break.

Do not substitute a different wire size, inside diameter, or spring length without completing a proper spring conversion. A spring may physically fit the torsion shaft while still producing incorrect or unsafe torque.

When replacing one spring in a matched two-spring system, replacing both springs is often recommended because springs installed together normally have similar operating histories.

What Is Included

• One SSC right-wind torsion spring
• Installed winding cone
• Installed stationary cone

The following items are not included unless specifically stated:

• Winding bars
• Torsion shaft
• Center bearing
• End bearing plates
• Center spring bracket
• Cable drums
• Lift cables
• Fasteners
• Installation tools

Installation Notes

Installation requires correctly sized solid-steel winding bars that fully engage the winding-cone holes.

Before installation:

• Close the garage door completely
• Disconnect electrical power to the opener
• Disengage the opener from the garage door
• Secure the garage door and torsion shaft against unintended movement
• Verify the spring wind direction
• Inspect the shaft, bearings, center bracket, drums, cables, and bottom fixtures
• Confirm that the lift cables are correctly positioned in the drum grooves
• Determine the correct number of winding turns for the specific door system

The required number of winding turns depends on the garage door height, cable-drum model, track configuration, spring engineering, and other system characteristics. Do not use a generic winding-turn recommendation without verifying the complete door setup.

After installation:

• Confirm equal lift-cable tension on both sides
• Verify that both cables remain correctly seated in the drums
• Test the garage door manually before reconnecting the opener
• Confirm smooth movement throughout the full door travel
• Check the balance at several intermediate positions
• Verify that the door does not fall rapidly or rise on its own
• Reconnect the opener only after the door is mechanically balanced
• Test the photoelectric sensors and contact-reversal system

The garage door opener must not be used to compensate for an incorrectly sized, under-wound, over-wound, or improperly installed torsion spring.

Safety Warning

Garage door torsion springs, winding cones, cable drums, lift cables, bottom brackets, and related components operate under extreme tension. Incorrect handling can cause severe injury, death, or major property damage.

Torsion-spring replacement should be completed only by a trained garage door professional with the correct tools, measurements, and knowledge of the complete counterbalance system.

Never:

• Loosen winding-cone set screws without controlling the spring with winding bars
• Use screwdrivers, punches, rebar, socket extensions, or improvised winding tools
• Stand directly in front of the winding cone while winding or unwinding
• Loosen bottom brackets while lift cables are under tension
• Install a spring without verifying its dimensions, torque, and wind direction
• Operate a door with loose cables, damaged drums, broken hardware, or poor balance
• Attempt installation when the correct winding procedure is unknown

Stop immediately if the spring specifications, torsion arrangement, drum setup, shaft configuration, or installation procedure cannot be positively verified.
