SSC .2625" × 1.75" ID × 39.50" Torsion Spring – LW – Blue

🇺🇸 Made in USA

The Service Spring Corp .2625" × 1.75" ID × 39.50" left-wind torsion spring is designed for garage door systems requiring this precise counterbalance specification. Its spring body is manufactured from coated, oil-tempered wire and supplied with installed winding and stationary cones.

When correctly matched to the door, the spring applies torque through the shaft and cable drums to help balance the door’s weight. This supports controlled movement throughout travel and reduces the lifting effort required from the opener. Accurate sizing is essential to achieve those results.

Specifications

Construction & Included Components

Oil-tempered wire forms the working coils that store and release mechanical energy during operation. The protective coating helps protect the wire surface, but does not eliminate the need for maintenance or inspection.

Winding and stationary cones are installed to provide the spring’s tensioning and fixed anchoring connections. Their suitability for the existing shaft and mounting arrangement must still be confirmed.

This listing includes one spring with cones. Other components, such as lift cables, cable drums, bearings, brackets, and the torsion shaft, are separate parts of the counterbalance system.

Common Applications

Intended for professional replacement on sectional garage doors specified for a .2625" wire × 1.75" inside diameter × 39.50" body length, left-wind spring.

The spring should not be selected by door width, opener model, or color alone. Doors with similar appearances can differ in weight and lift geometry. If the previous spring did not balance the door correctly, a technician should calculate the appropriate specification instead of repeating the existing size.

Compatibility & Measurement

Confirm all four essential specifications before purchase. The 39.50" body length excludes the cones and refers to the spring in its fully relaxed state, not its length under tension.

The 1.75" inside diameter is the spring coil opening rather than the shaft diameter. Check cone fit, anchor compatibility, available space, and the condition of the surrounding hardware separately.

This spring is not interchangeable solely by appearance with a .2625" × 2.00" ID × 39.25" spring. Both coil diameter and length differ, affecting spring characteristics. A suitable alternative must be calculated for the door’s complete counterbalance requirement.

Wind Direction & Color Identification

Left wind describes coil direction. Correct placement must be established from the actual torsion system arrangement rather than a universal left-side or right-side assumption.

Blue identifies .2625" wire in the torsion spring color-code system. It should not be confused with the light-blue identification used for .2830" wire. Color markings assist identification but do not replace measurement or indicate door lifting capacity.

Pairing & Door Configuration

In a two-spring assembly, both springs contribute to the door’s balance. The installer should consider their combined output and inspect the companion spring for age-related wear or damage.

Replacing both may be appropriate when their service histories are similar. However, a correctly engineered pair may use different dimensions. Door weight, height, cable drum geometry, and lift type must guide the final selection.

Cycle Life & Maintenance

This spring carries a listed minimum rating of 10,000 cycles in the correct application. One complete opening and closing is one cycle; the rating does not guarantee a fixed number of years.

Follow manufacturer maintenance recommendations. A change in balance, unusual noise, or irregular cable movement requires professional attention. Increasing opener force does not resolve an incorrect spring selection.

Professional Installation & Safety

A qualified garage door professional should perform removal, installation, and tensioning. Never loosen loaded spring cones, anchors, drums, or bottom cable brackets.

After replacement, have spring clearance, cable condition, bearings, mounting hardware, door balance, and opener safety functions checked.

Choose this spring when the verified specification is .2625" × 1.75" ID × 39.50", left wind.
