Key Features
- Genuine OEM Construction — Produced to Genie's original material and dimensional standards, delivering the structural integrity expected of a mounting plate that supports outrigger loads.
- Direct-Fit Replacement — Engineered to match the original mounting holes, profile, and thickness of the GS84 HF outrigger mount, so installation aligns with existing hardware.
- Broad GS Large-Platform Compatibility — Fits the GS-3384, GS-3390, GS-4390, and GS-5390 scissor lifts — Genie's heavy-duty, large-platform GS series models.
- Structural Reliability — A properly seated outrigger mount plate maintains the secure connection between the outrigger assembly and the machine frame, supporting stable operation on the worksite.
- Safety-Critical Component — Outrigger mounting hardware is integral to machine stability. Replacing a damaged or worn plate with the correct OEM part helps preserve the structural integrity of the outrigger system.
The outrigger mount plate is a structural bracket that secures the outrigger assembly to the machine's frame. It distributes the load imposed by the outriggers during leveling and operation, keeping the connection between the outrigger and the chassis firm and correctly aligned. A cracked, bent, or worn mount plate compromises that connection — leading to movement at the outrigger joint, uneven support, and potential instability — making prompt replacement with the correct OEM part essential.
