The Genie 31379GT is a genuine OEM Tension Spring, 1.25 x.438 Dia built for Genie S and Z series boom lifts, including the S-60 J, Z-34/22 IC, Z-34 IC, and Z-45/22 MP. As a direct OEM replacement, this spring is manufactured to the same specifications as the original, ensuring a correct fit with no guesswork at installation. Cross-reference part number 31379GT against your machine's parts manual to confirm it is the right spring for your unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original dimensional and material specifications, delivering the same tension rating and coil geometry as the part it replaces.
- Exact-Fit Replacement — Designed to swap directly into the same mounting position as the original, with matching length of 1.25 inches and wire diameter of .438 inches.
- Broad Boom Lift Compatibility — Fits the S-60 J telescopic boom and Z-34/22 IC, Z-34 IC, and Z-45/22 MP articulating booms, covering both S and Z series families.
- Consistent Return Force — A spring at its correct tension rating holds or returns a component reliably under load; a fatigued or broken spring allows unwanted movement or fails to reset a mechanism, leading to sluggish or non-functional operation.
- Operational Safety — On aerial boom lifts, a correctly tensioned spring is essential to the reliable operation of the mechanisms it supports; replacing a worn spring with the correct OEM part helps keep those mechanisms functioning as designed.
A tension spring stores mechanical energy by stretching under load and pulls connected components back toward their resting position when the load is released. On boom lifts, tension springs are used in control linkages, latch mechanisms, and return assemblies where a reliable, repeatable return force is required. When a tension spring loses its rated tension through fatigue or breaks entirely, the mechanism it supports may fail to return to its neutral position, respond inconsistently, or stop functioning altogether. Replacing a worn spring promptly with the correct OEM part restores the intended operation and helps prevent secondary wear on surrounding components.
