The Genie 74798GT is a genuine OEM Upper Level Arm designed for Genie Z-25/8, Z-20/8, and Z-20/8N articulating boom lifts. Sourced directly from Genie, this component matches the original part in geometry, material, and mounting configuration — ensuring a verified, direct fit on the machines it was engineered for. Whether you are restoring a unit to full working order or replacing a damaged arm before it causes further issues, this is the correct OEM part for the job. Cross-reference part number 74798GT against your Genie parts manual to confirm fitment for your serial range.
Key Features
- Genuine OEM Structural Integrity — Manufactured to Genie's original design specifications, with the correct material grade and geometry to handle the dynamic loads placed on the upper level arm during articulation.
- Direct Bolt-On Replacement — Matches original mounting points and pivot geometry on Z-series articulating booms, so this arm installs without rework or modification to surrounding hardware.
- Confirmed Fitment for Z-Series Articulating Booms — Built for the Z-25/8, Z-20/8, and Z-20/8N — compact articulating boom lifts in the Genie Z-series lineup.
- Restores Full Boom Articulation — A worn or damaged upper level arm compromises the boom's ability to articulate accurately and hold position, directly affecting platform reach and operator control.
- Critical to Safe Platform Positioning — On an articulating boom lift, the structural soundness of each arm segment is essential to controlled, safe platform movement — making this a genuine safety-relevant component that should only be replaced with an OEM-verified part.
The upper level arm is a primary structural link in the articulating boom assembly, connecting the upper boom section to the platform or jib and transmitting both the lifting force and the articulation movement that positions the platform precisely. On compact Z-series machines like the Z-25/8 and Z-20/8, this component operates under repeated cyclic stress as the boom extends, retracts, and articulates across its range of motion. When this arm is bent, cracked, or worn at its pivot points, the boom loses positional accuracy and structural rigidity — conditions that must be corrected before the machine returns to service.
