The Genie 1256117GT is a genuine OEM Shim Washer, 1.56X3.5X.061, ZAG, designed for a broad range of Genie telescopic boom lifts, articulating boom lifts, and GTH telehandlers. As a direct OEM replacement, this shim washer meets the original engineering tolerances specified for these machines, delivering the precise stack height and load distribution the assembly requires. This component fits the S-40 and S-45 telescopic booms, the Z-45/22 articulating boom, and the full GTH telehandler lineup — including the GTH-636, GTH-844, GTH-1044, GTH-1048, GTH-1056, GTH-1244, GTH-1256, GTH-1544, GTH-644, and GTH-842. Cross-reference part number 1256117GT against your Genie parts manual to confirm the correct application before ordering.
Key Features
- Genuine OEM Thickness Tolerance — Manufactured to the exact ZAG specification at 1.56 x 3.5 x .061, ensuring the shim seats correctly and delivers the intended preload or clearance in the assembly.
- Drop-In OEM Replacement — Matches the original mounting footprint and material grade, so this washer installs directly into the existing stack without reworking surrounding components.
- Wide Cross-Platform Fitment — Fits Genie S-series telescopic booms, the Z-45/22 articulating boom, and a broad range of GTH telehandlers, making this a practical stocking part for mixed Genie fleets.
- Maintains Proper Load Distribution — A correctly specified shim washer keeps mating surfaces properly spaced and loaded; an incorrect thickness — or a worn-out shim — can introduce play, accelerate wear on adjacent components, and compromise structural alignment.
- Structural Integrity Assurance — In boom lifts and telehandlers, shim stack accuracy directly affects the alignment of load-bearing pivot and structural joints, making correct shim selection a genuine safety consideration for aerial and lifting equipment.
A shim washer is a precision-thickness spacer placed between mating components to set a specific gap, preload, or alignment within an assembly. In boom lifts and telehandlers, shim washers are commonly used at structural pivot points, boom articulation joints, and drive-system interfaces, where even a small variance in spacing can affect how load is transferred between components. When a shim washer wears thin, deforms, or is replaced with an incorrect thickness, the result is unwanted play in the joint, uneven contact stress, and accelerated wear on surrounding hardware — making it essential to replace this part with one that matches the original specification exactly.
