SSC .2343" × 1.75" ID × 35.00" Torsion Spring – LW – Brown

🇺🇸 Made in USA

The Service Spring Corp .2343" × 1.75" ID × 35.00" left-wind torsion spring is a replacement counterbalance component for garage door systems requiring these exact specifications. It works through the torsion shaft and cable drum assembly to help offset the door’s weight during opening and closing.

This spring is manufactured from coated, oil-tempered wire and supplied with winding and stationary cones installed. Brown wire-size identification corresponds to .2343" wire, while the complete dimensional specification and left-hand wind provide the information needed for accurate selection.

Specifications

Construction & Included Components

Oil-tempered spring wire forms the working coil body. The protective coating helps protect its surface during service, but does not eliminate the need for proper inspection and manufacturer-recommended maintenance.

Installed winding and stationary cones provide the connections used to tension and anchor the spring. Their suitability for the existing shaft and mounting arrangement must still be confirmed.

This listing includes one spring with cones. Cables, cable drums, bearings, brackets, torsion shaft, and installation equipment are separate parts of the complete system.

Common Applications

Intended for professional replacement on sectional garage doors specified for a .2343" wire × 1.75" inside diameter × 35.00" body length, left-wind spring.

Spring selection should be based on verified measurements and the door’s counterbalance requirements. Door width or opener model alone cannot establish compatibility. A previously unbalanced door, or one modified with heavier panels, reinforcement, or insulation, may require a new spring calculation.

Compatibility & Measurement

Match all four primary characteristics: wire diameter, inside diameter, relaxed body length, and wind direction. The 35.00" measurement excludes the winding and stationary cones and refers to the spring body without tension.

The 1.75" inside diameter describes the opening through the spring coils. It does not specify the torsion shaft diameter. Confirm cone fit, anchor mounting, shaft compatibility, and adequate operating clearance separately.

This spring differs from a .2343" × 1.75" ID × 31.50" spring even though the wire diameter and coil diameter match. The additional body length changes spring rate, so the two should not be substituted without evaluating the complete counterbalance requirement.

Wind Direction & Color Identification

Left wind describes coil direction. Correct installation position depends on the actual torsion assembly and should not be determined solely from which side of the door a spring occupies.

Brown is the wire-size code for .2343" torsion spring wire. It is an identification aid, not a door weight rating. Faded, missing, or repainted markings make direct measurement especially important.

Pairing & Door Configuration

For a two-spring system, both springs must be considered together. The technician should inspect the companion spring and determine whether replacement of both is appropriate based on age, condition, and the intended combined output.

A properly engineered pair may use different spring dimensions. Door weight, travel height, cable drum geometry, and standard-, high-, or vertical-lift configuration guide the correct pairing. A longer spring is not automatically a compatible upgrade.

Cycle Life & Maintenance

The listed minimum rating is 10,000 cycles in the correct application. One complete opening and closing counts as one cycle. Daily use, environmental exposure, and the condition of surrounding hardware affect actual service duration.

Follow manufacturer recommendations for inspection and lubrication. A door that becomes heavy, uneven, or unusually noisy should be serviced before continued operation creates additional problems.

Professional Installation & Safety

Installation, removal, and tensioning require a qualified garage door professional using suitable equipment. Never loosen loaded cones, spring anchors, cable drums, or bottom cable brackets.

After installation, have the technician verify secure mounting, cable condition, spring clearance, door balance, and opener safety functions.
