The Genie 74797GT is a genuine OEM Upper Level Arm Assembly designed for Genie Z-25/8, Z-20/8, and Z-20/8N articulating boom lifts. Sourced directly from Genie, this assembly delivers an exact OEM match — ensuring the structural and mechanical integrity your machine depends on. Cross-reference part number 74797GT against your parts manual to confirm fitment for your specific serial range before ordering.
Key Features
- Genuine OEM Structural Integrity — Built to the same specifications as the original assembly, with correct geometry and load-bearing capacity for the upper boom section of Genie Z-series articulating lifts.
- Direct Bolt-In Replacement — Engineered to align with existing mounting points and pivot hardware on compatible Z-series machines, so installation stays straightforward without fabrication or adaptation.
- Confirmed Fitment for Z-Series Booms — Compatible with the Z-25/8, Z-20/8, and Z-20/8N articulating boom lifts. Always verify your machine's model code and serial number before ordering.
- Maintains Full Boom Articulation — A correctly functioning upper level arm assembly allows the boom to articulate smoothly and hold platform position accurately. A damaged or worn arm can introduce play, misalignment, or loss of platform control.
- Aerial-Lift Safety Critical — The upper level arm is a structural load-bearing component. Using a genuine OEM replacement supports the mechanical reliability required for safe operation at height.
The upper level arm assembly is a core structural component of the articulating boom system, connecting the upper boom section to the rest of the lift's articulating linkage. It transmits load forces and guides the precise range of motion that positions the platform at the correct height and angle during operation. When this assembly is bent, cracked, or worn at its pivot points, the boom may exhibit abnormal movement, poor platform positioning, or structural instability — making timely replacement essential for keeping the machine in safe working order.
