SSC .2343" × 1.75" ID × 28.25" Torsion Spring – LW – Brown

🇺🇸 Made in USA

Replace a matching garage door counterbalance spring with this SSC left-wound torsion spring. It combines .2343" wire, a 1.75" inside diameter, and a 28.25" relaxed spring-body length, with winding and stationary cones installed.

The coated, oil-tempered wire stores and releases torque as the door moves. When correctly selected, the spring works with the shaft, cable drums, cables, and any companion spring to offset door weight throughout the operating cycle.

Specifications

Construction & Included Fittings

Oil-tempered wire provides the spring material for repeated torque loading. The coating helps protect its surface, although appropriate inspection and maintenance remain necessary.

The winding and stationary cones are installed. Their fit must be verified against the torsion shaft and stationary anchor arrangement. Installed cones do not make spring replacement a homeowner task.

This listing includes one spring with cones. An opposite-wind spring, shaft, drums, cables, bearings, brackets, and professional installation tools are separate components.

Common Applications

For professional replacement of a matching left-wound spring on a sectional garage door or use in a professionally calculated spring combination.

Compatibility is determined by the complete counterbalance requirements. Door width, opener horsepower, or a brown marking alone does not establish whether this spring is suitable.

Exact Dimensions & Replacement Fit

Confirm .2343" wire diameter, 1.75" inside diameter, 28.25" relaxed body length, and left-hand wind.

The 28.25" length should not be rounded to 28.00" or 29.00". Changing body length changes the spring rate, which can affect balance throughout the door’s travel.

The 1.75" ID must also match the verified specification. A .2343" spring with a 2.00" ID can have different operating characteristics and fitting requirements, even when its length appears similar.

The stated length excludes both cones and refers to the relaxed coil body. An installed spring under tension can measure longer. Have measurements safely confirmed rather than attempting to unwind the spring yourself.

Check cone bore, shaft fit, stationary mounting, and available assembly space separately from the spring’s inside diameter.

Brown Color Code & Left-Hand Wind

Brown is the wire-size identification color. LW identifies the direction of the coil. Neither marking establishes a universal lifting capacity.

This is the left-wound version of this spring configuration. The right-wound version is not an interchangeable replacement. Confirm the wind required by the actual system rather than relying solely on the old spring’s position.

Pairing, Drums & Lift Configuration

Have both springs evaluated when servicing a two-spring door. Replacing both aging springs may be appropriate, but the correct replacement combination must provide the door’s required combined torque and spring rate.

Do not assume both springs must be identical. Some engineered assemblies use different dimensions. Added door weight, different cable drums, or changes in lift configuration require a new sizing review. High-lift and vertical-lift systems need application-specific calculations.

Cycle Life & Maintenance

The standard minimum rating is 10,000 cycles in a correctly selected application. One complete opening and closing equals one cycle. Actual service life depends on operating frequency, loading, environment, and maintenance.

Follow the door manufacturer’s inspection and lubrication guidance. Arrange service if the door becomes heavy, moves unevenly, or develops unusual noise. Increasing opener force is not a solution for poor spring balance.

Professional Installation & Safety

Torsion springs store hazardous energy. Installation and tension adjustment must be performed by a qualified garage door technician using proper winding bars and approved procedures.

Never loosen loaded cones, drums, anchors, or bottom cable brackets. Keep a door with a broken spring out of operation. After installation, inspect supporting hardware and verify door balance, cable operation, and opener safety functions.

Order this SSC left-wound spring after confirming the 1.75" ID, exact 28-1/4" body length, and requirements of your complete counterbalance system.
