Garage Door Torsion Spring – Left Wind .2253 Wire x 1.75" ID x 120" Long Length Coated Spring with Cones

Spring Specifications

• Made in the USA
• All springs rated for an industry standard minimum lifecycle of 10,000 cycles
• Springs come with winding and stationary cones installed and are stenciled and color coded for easy identification
• Coated & oil tempered wire

Compatible with:

• Sectional overhead garage door systems using long-length torsion spring setups
• 1.75" inside diameter torsion shaft systems
• Residential and light commercial garage doors requiring matched LW/RW spring pairs
• Systems using standard cable drums, torsion shafts, and center/end bearing plate assemblies
• Applications requiring distributed-load spring configurations for improved cycle performance
• Major garage door brands including Clopay, Amarr, CHI, Wayne Dalton, Midland, Haas Door, and similar systems when specifications match existing setup

Important: LW and RW springs must always be matched as a pair and selected based on door weight, drum size, and engineering calculations—not dimensions alone.

Applications

• Replacement of worn or broken long-length torsion springs
• High-cycle residential garage door systems
• Light commercial overhead door applications
• Preventive maintenance upgrades for improved cycle life
• Balanced counterweight system restoration (LW/RW pairs)
• Professional garage door repair and installation work

How This Part Fits Into the Garage Door System

The torsion spring is a core component of the garage door counterbalance system, mounted on the horizontal torsion shaft above the door opening. This left-wind spring works in opposition to the right-wind spring to store and release rotational energy as the door moves through its open and close cycles.

In a long-length system, torque is distributed across a greater coil span, which reduces individual coil stress and improves fatigue resistance. This allows for smoother operation, improved cycle life, and more stable balance across the full range of door movement.

This spring works together with:

• Torsion shaft
• Cable drums
• Lift cables
• Center bearing plate
• End bearing plates
• Garage door sections and hardware
• Garage door opener system

When properly matched as part of an LW/RW pair, the system maintains even torque distribution, prevents uneven lifting, reduces opener strain, and protects cables, rollers, and tracks from excessive wear. A failing or mismatched spring can result in imbalance, jerky movement, cable slippage, and increased safety risk. Proper replacement restores full system equilibrium and reliable operation.
