The Genie 1278788GT is a genuine OEM Wear Pad Shim, 9 X 3.5, 12GA designed for Genie S-series telescopic boom lifts, including the S-40 XC, S-45 XC, S-40 TRAX, S-45 TRAX, S-40 HF, and S-45 HF. As a direct OEM replacement, this shim is manufactured to Genie's original specifications, ensuring the correct thickness, material gauge, and dimensional profile for a straight-swap installation. Cross-reference part number 1278788GT against your machine's parts manual to confirm it is the right item for your unit before ordering.
Key Features
- OEM-Grade Material and Dimensional Conformity — Stamped to 12GA and cut to a 9 x 3.5 profile, this shim meets the original Genie specification for material thickness and footprint, so it seats correctly without adjustment.
- Direct Drop-In Replacement — Engineered to match the original part geometry, this shim installs in the same position as the factory component with no rework to surrounding hardware.
- Broad S-Series Coverage — Fits the S-40 XC, S-45 XC, S-40 TRAX, S-45 TRAX, S-40 HF, and S-45 HF telescopic boom lifts from a single part number.
- Maintains Boom Section Alignment — A correctly shimmed wear pad keeps boom sections tracking smoothly and evenly. A worn or missing shim allows play between sections, leading to uneven wear, noise, and imprecise boom movement.
- Genuine OEM Confidence — Sourced directly from Genie, this part carries the OEM designation, giving fleet managers and service technicians assurance that the replacement matches the original in every measurable way.
A wear pad shim is a precision-thickness spacer positioned between the boom sections of a telescopic boom lift to control the clearance between the inner and outer boom tubes. By maintaining the correct gap, the shim ensures boom sections slide in and out smoothly and that the wear pads themselves contact the boom tubes evenly, extending the service life of those pads. When a shim wears down, becomes deformed, or is missing entirely, boom sections develop excess play, causing uneven wear on surrounding components, rough extension and retraction, and reduced control accuracy at the platform — all of which signal that the shim needs to be inspected and replaced with the correct OEM part.
