The Genie 56291GT is a genuine OEM Hardened Washer, 5/8 designed for Genie Z-series articulating boom lifts, including Z-34/22 and Z-45/25 variants. As a direct OEM replacement, this washer is manufactured to the exact material hardness and dimensional tolerances specified for these machines, ensuring a proper fit without rework or modification. It is verified to fit the Z-34/22 N, Z-34/22 DC, Z-34/22 Bi-Energy, Z-45/25, Z-45/25J DC, and Z-45/25J Bi-Energy. Cross-reference part number 56291GT against your Genie parts manual to confirm this is the correct component for your machine before ordering.
Key Features
- Hardened Steel Construction — Manufactured to OEM hardness specifications, this washer resists deformation under the high clamping loads typical in articulating boom lift assemblies.
- Drop-In OEM Replacement — Matches the original 5/8 sizing exactly, seating flush against mating fasteners and surfaces the same way the factory-installed component does.
- Broad Z-Series Compatibility — Fits six Z-34/22 and Z-45/25 model variants, including N, DC, and Bi-Energy configurations, covering a wide range of fleet equipment.
- Protects Structural Fastener Joints — A correctly spec'd hardened washer distributes load evenly across bolted connections, preventing surface galling, fastener pull-through, and joint loosening over time.
- Structural Integrity on Elevated Equipment — On articulating booms, fastener hardware at pivot and structural joints is critical to safe platform operation — using the correct hardened washer maintains the integrity of those connections.
A hardened washer serves as a load-distribution component in bolted joints, spreading the clamping force of a fastener over a larger surface area to prevent damage to the joined materials. On articulating boom lifts like the Z-34/22 and Z-45/25 series, these washers are used at structural, pivot, and mounting points that experience significant dynamic loads during operation and travel. When a washer is undersized, soft, or worn, fastener joints can loosen prematurely, surfaces can gall or deform, and the integrity of critical connections can be compromised — making prompt replacement with the correct OEM-spec component essential.
