Gardner Spring 37083GS Extension Spring 5/8 in Od 16.52 Lb

Product Description

The GARDNER SPRING 37083GS is a steel extension spring designed for applications requiring reliable tensile force across a range of light-to-medium-duty mechanical systems. With an outside diameter of 0.625 inches, a free length of 4.5 inches, and a wire diameter of 0.069 inches, this spring delivers a spring rate of 3.48 lb/in and supports a maximum load of 16.52 pounds before reaching its extended length limit of 8.68 inches. It is used by mechanical technicians, HVAC service pros, and general industrial maintenance personnel in assemblies where controlled return tension is needed. This part ships in a pack of 3.

Extension springs in this size class are commonly found in residential and light commercial equipment including HVAC damper linkages, door mechanisms, counterbalance assemblies, and general mechanical linkages where a consistent return force is required. The 37083GS is suited for environments where precise spring rate and load tolerance matter, and where standardized hook-end geometry simplifies drop-in replacement or new assembly installation.

Key Features

• Outside diameter of 0.625 inches for consistent fit in standard spring pockets and guides
• Spring rate of 3.48 lb/in provides predictable, linear tension across the working range
• Maximum extended length of 8.68 inches with a free length of 4.5 inches
• Wire diameter of 0.069 inches for adequate strength in light-to-medium load applications
• Maximum work load of 16.52 pounds before reaching extension limit
• Sold in a quantity of 3 per package, reducing per-unit cost for service stock

Compatibility

Designed as a standard-geometry extension spring suitable for light-to-medium-duty mechanical assemblies requiring a 5/8 inch OD spring with a 3.48 lb/in spring rate and inside hook ends.

Installation Notes

Extension springs should be installed by qualified mechanical or HVAC technicians following all applicable equipment service procedures. Always de-energize or power down the associated equipment before handling spring assemblies. Do not stretch the spring beyond its published maximum extended length, as permanent deformation or failure may result. Inspect hook ends and mounting points for wear or deformation before installing replacement springs.
