The Genie 823877GT Upper Secondary Arm Assembly is a genuine OEM structural component designed for Z-45/25, Z-45/25J DC, Z-45/25J Bi-Energy, Z-45/25J IC Power, and Z-45 XC articulating boom lifts. As a direct OEM replacement, this assembly is manufactured to the same specifications as the original part, ensuring correct geometry, load ratings, and connection points throughout the boom structure. Cross-reference part number 823877GT against your parts manual to confirm fitment for your specific machine serial range before ordering.
Key Features
- Genuine OEM Structural Integrity — Built to Genie's original design tolerances for this load-bearing arm assembly, maintaining the boom's engineered articulation geometry and structural strength.
- Direct Drop-In Replacement — Matches the original mounting points, pivot hardware interfaces, and arm profile of the Z-45 series boom structure for a straightforward installation.
- Broad Z-45 Series Coverage — Fits multiple Z-45 variants including the Z-45/25, Z-45/25J DC, Z-45/25J Bi-Energy, Z-45/25J IC Power, and Z-45 XC articulating boom lifts.
- Restores Full Boom Articulation — A correctly functioning secondary arm assembly enables smooth, precise boom movement through its full range of motion, supporting platform positioning accuracy on the jobsite.
- Critical Aerial Work Safety Component — The secondary arm is a primary structural element of the boom system. Replacing a cracked, bent, or worn assembly restores the structural integrity required for safe elevated operation.
The upper secondary arm assembly is a key structural link in an articulating boom lift's upper boom system. It connects the upper boom sections and transmits both the mechanical forces generated during lifting and the loads applied at the platform, allowing the boom to articulate smoothly through its designed range of motion. When this component is damaged or worn — whether through impact, metal fatigue, or stress fracture — the boom's geometry is compromised, which can affect platform positioning, load capacity, and the overall structural reliability of the machine during elevated use.
