The Genie 122439GT is a genuine OEM S120/125 Function Manifold built for Genie S-120HD, S-120, S-125, and S-3800 telescopic boom lifts. As a direct OEM replacement, this manifold meets Genie's original engineering requirements, ensuring correct porting, internal passage geometry, and port thread compatibility with no adaptation needed. Cross-reference part number 122439GT against your machine's parts manual to confirm it is the correct manifold for your unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original specifications, ensuring correct port sizing, thread form, and internal passage dimensions for this manifold application.
- Direct OEM Replacement — Mounts and connects exactly as the original, restoring the manifold to its correct position and sealing against the surrounding components without rework.
- Confirmed Fitment — Designed specifically for Genie S-120HD, S-120, S-125, and S-3800 telescopic boom lifts; always verify part number 122439GT against your serial-number range in the parts manual.
- Restored Function Control — A correctly seated function manifold keeps fluid routed to the right circuits on demand; a cracked, leaking, or damaged manifold disrupts machine function and should be replaced promptly.
- Operational Safety — On large telescopic boom lifts, proper manifold operation is directly linked to controlled boom movement and platform positioning — using the correct OEM part supports safe, predictable machine behavior.
A function manifold is a ported block that directs fluid flow to the various machine functions — such as boom extension, lift, and swing — in response to operator commands. It consolidates multiple fluid paths into a single serviceable assembly, keeping the circuit layout compact and the flow routing precise. When a function manifold leaks internally or externally, machine functions can become sluggish, unresponsive, or uncontrolled, making prompt replacement with the correct OEM part essential on large telescopic boom lifts like the S-120 and S-125 series.
