The Genie 1284093GT Cylinder Primary Extension Seal Kit is a genuine OEM sealing kit designed for the Genie S-65 XC telescopic boom lift. Sourced directly from Genie, this kit delivers the correct seals, dimensions, and materials to restore the primary extension cylinder to proper operating condition. As a genuine OEM part, it matches the original engineering specifications and slots in without modification. Confirm part number 1284093GT against your machine's parts manual to ensure it is the correct kit for your unit's serial range before ordering.
Key Features
- Genuine OEM Seal Materials — Manufactured to Genie's original material and compression specifications, ensuring the seals perform the way the cylinder was engineered to operate.
- Direct-Fit Replacement — Each seal in the kit is sized and profiled to match the primary extension cylinder exactly, so installation follows the standard service procedure without alteration.
- Designed for the S-65 XC — Confirmed fitment for the Genie S-65 XC telescopic boom lift; cross-reference 1284093GT with your parts manual before ordering.
- Restores Cylinder Integrity — Worn or damaged seals allow fluid to bypass the piston or weep externally, robbing the cylinder of pressure and causing sluggish or inconsistent extension. Replacing them with a correctly specified kit restores full, consistent cylinder travel.
- Operational Safety — On an aerial boom lift, a primary extension cylinder that cannot hold pressure is a functional hazard. Installing the correct OEM seal kit keeps the extension system performing within its designed operating parameters.
The primary extension cylinder moves the boom outward to reach the working position, and its seals are what allow it to hold and build pressure during that travel. Over time, seals harden, compress, or tear — leading to fluid weeping past the piston, visible external leakage, or a boom that drifts or extends inconsistently. A seal kit replaces the full set of sealing elements inside the cylinder, addressing the root cause rather than masking the symptom. Using the correct OEM kit means the replacement seals match the bore, rod diameter, and groove geometry of the original cylinder, giving the rebuilt cylinder the same service life as a new one.
