The Genie 65788GT is a genuine OEM Cylinder 54570GT Seal Kit designed for Z-45/25 and Z-45/25J articulating boom lifts, including IC Power, DC, and Bi-Energy variants. As a direct OEM replacement, this seal kit is manufactured to the exact specifications required for cylinder 54570GT, ensuring a correct, consistent fit without guesswork. Cross-reference part number 65788GT against your machine's parts manual to confirm this is the right kit for your unit before ordering.
Key Features
- Genuine OEM Sealing Materials — Manufactured to the original material grade and dimensional tolerances required for cylinder 54570GT, so each seal seats and compresses correctly on installation.
- Cylinder-Specific Fit — Engineered specifically for cylinder 54570GT; every seal, wiper, and o-ring in the kit matches the bore and groove dimensions of that cylinder assembly.
- Broad Z-45/25 Family Coverage — Fits the full Z-45/25 and Z-45/25J range, spanning IC Power, DC, and Bi-Energy configurations, so one kit covers the most common variants in your fleet.
- Restores Fluid Containment — Worn or degraded cylinder seals allow fluid to bypass the piston or weep externally, causing cylinder drift and loss of lift control. A fresh seal kit restores full containment and consistent cylinder travel.
- Supports Safe Aerial Operation — On an articulating boom lift, a cylinder that drifts or bleeds down under load is a direct safety concern. Replacing seals at the first sign of leakage keeps the boom holding position as designed.
A cylinder seal kit contains the complete set of seals, wipers, and o-rings needed to rebuild a hydraulic cylinder during service. Over time, seals harden, crack, or take a compression set, allowing fluid to bypass the piston internally or escape past the rod externally — both conditions cause the cylinder to drift or lose holding force. Replacing the full seal set restores proper fluid containment so the cylinder extends, retracts, and holds its position reliably. Using the correct OEM kit for cylinder 54570GT ensures every seal matches the original groove dimensions and material spec, reducing the risk of premature failure after the rebuild.
