The Genie 121388GT is a genuine OEM Taper Pin, 2.50 Dia x 24.50, 2 Rings, Taper built for Genie S-80 and S-85 series telescopic boom lifts, including XC, HF, FE, and E variants. As a factory-sourced component, this pin matches the original dimensional specification, ensuring correct installation in the boom structure without rework or modification. It fits the full S-80 and S-85 family — including S-80X, S-80 XC, S-85 XC, S-85 HF, S-85 XC FE, and S-85 XC E models — making it the straightforward choice when the original pin is worn, bent, or missing. Always cross-reference part number 121388GT against your machine's parts manual to confirm it is the correct item for your serial number.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Genie's original 2.50-diameter by 24.50-length specification with a tapered profile, so the pin seats correctly in its bore without shimming or adjustment.
- Dual Retaining Rings — The two-ring design secures the pin in position under load, preventing axial movement that would allow slop or misalignment in the joint it fastens.
- Direct OEM Replacement — Sourced from Genie as a genuine OEM part, this pin installs directly in place of the original with no machining or adaptation needed.
- Broad S-80 and S-85 Family Coverage — Fits the S-80X, S-80, S-85, S-80 XC, S-85 XC, S-80 HF, S-85 HF, S-85 XC FE, and S-85 XC E, covering the full range of these telescopic boom variants.
- Structural Connection Integrity — A correctly fitted taper pin maintains tight, play-free connections at pivoting or articulating joints on the boom structure. A worn or undersized pin allows movement that accelerates wear on surrounding components and can affect boom control.
- Safety-Critical Joint Component — On aerial boom lifts, pins that secure structural joints are load-bearing safety components. Using the correct OEM pin with the specified taper and retaining-ring groove geometry ensures the joint performs as Genie designed it.
A taper pin is a precision fastener used to lock two components together at a pivot or hinge point, transmitting load across the joint while preventing rotation or axial shift between mated parts. On a telescopic boom lift, these pins are found at structural connection points throughout the boom and chassis — where the taper allows the pin to wedge firmly into its bore for a tight, rattle-free fit. When a taper pin wears, corrodes, or shears, the joint it holds develops play, which places undue stress on the surrounding bore, the retaining rings, and the adjoining structure. Replacing a worn pin promptly with the correct OEM component restores the joint to its original specification and prevents accelerated wear on the components around it.
