The Genie 59263GT is a genuine OEM Seal Kit, 3" Bore x 1.5" Rod built for Genie S-45 telescopic boom lifts and Z-45/25 series articulating boom lifts, including the Z-45/25J IC Power, Z-45/25J DC, and Z-45/25J Bi-Energy variants. As a direct OEM replacement, this kit contains the correct seals sized to a 3-inch bore and 1.5-inch rod, ensuring the cylinder it services is restored to proper working condition. Cross-reference part number 59263GT against your machine's parts manual to confirm it is the correct kit for your specific cylinder before ordering.
Key Features
- OEM Seal Material and Dimensional Accuracy — Genuine Genie seals manufactured to the exact bore and rod dimensions (3" bore x 1.5" rod) required for a proper, leak-free fit.
- Complete Kit Format — Supplies the full set of seals needed to service the cylinder in one order, avoiding multiple part lookups and partial repairs.
- Direct OEM Replacement — Sourced directly from Genie, this kit installs to the same specification as the original seals, with no modification to the cylinder required.
- Broad Model Coverage — Fits the S-45 telescopic boom and multiple Z-45/25 articulating boom variants, including IC Power, DC, and Bi-Energy configurations.
- Restores Cylinder Performance — Worn or damaged seals allow fluid to bypass the piston or leak externally, causing the cylinder to drift, lose extension force, or fail to hold position. Fresh OEM seals restore full cylinder function.
- Operational Safety — On aerial boom lifts, a cylinder that cannot hold its position under load creates a genuine risk to operators at height. Replacing seals at the first sign of weeping or drift is a critical part of keeping the machine safe and operational.
A cylinder seal kit replaces the seals that prevent fluid from bypassing the piston inside a cylinder or escaping past the rod. Over time, seals degrade from heat cycling, pressure, and normal wear, leading to internal bypass or external leakage. When this happens, the cylinder loses its ability to extend fully, hold a load, or maintain its position — symptoms that become especially serious on boom lifts where platform height and stability depend on the cylinder staying locked. Replacing the seals with a correctly sized OEM kit, matched to the 3-inch bore and 1.5-inch rod dimensions, restores the cylinder's integrity and returns the machine to safe working condition.
