The Genie 74379GT Upper Secondary Arm Assembly, Z34 is a genuine OEM component built for Genie Z-34 series articulating boom lifts, including the Z-34/22 N, Z-34/22 IC, and Z-34 IC. As a direct OEM replacement, this assembly meets the original design specifications and installs in place of the worn or damaged unit without modification. Cross-reference part number 74379GT against your machine's parts manual to confirm it is the correct assembly for your serial number and configuration before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original design specifications, ensuring dimensional accuracy and material integrity for a structural arm assembly that bears significant load and stress in operation.
- Direct OEM Replacement — This assembly replaces the upper secondary arm on Z-34 articulating booms, installing in the original mount points without reworking the surrounding structure.
- Confirmed Fitment for Z-34 Series — Designed for the Z-34/22 N, Z-34/22 IC, and Z-34 IC articulating boom lifts; verify against your parts manual to confirm applicability to your unit.
- Structural Integrity Restored — A worn or damaged secondary arm can compromise boom articulation and platform positioning; replacing it with the correct OEM assembly restores proper range of motion and structural support.
- Critical Safety Component — As a primary structural element of the boom linkage on an aerial work platform, the upper secondary arm must be in sound condition to support safe platform operation at height.
The upper secondary arm assembly is a key structural link in the articulating boom system of the Z-34 series. It connects sections of the boom's folding linkage, allowing the platform to be raised, extended, and positioned accurately. When this arm is bent, cracked, or worn at its pivot points, boom articulation becomes inconsistent and the platform may not reach or hold its intended position — conditions that ground the machine until the component is replaced. Installing the correct OEM assembly restores the boom's full range of motion and keeps the lift operating as designed.
