This kit covers Z-45/25J IC Power, Z-45/25J DC, Z-45/25J Bi-Energy, Z-45/25 IC, Z-45/25J IC, and Z-45/22 variants.
Key Features
- Genuine OEM Seal Material — Manufactured to Genie's OEM specifications, with seal compounds and dimensional tolerances matched precisely to cylinder 54570GT.
- Cylinder-Specific Fit — Designed exclusively for cylinder 54570GT, so every seal in the kit corresponds to the correct bore, groove, and seat dimensions of that cylinder.
- Broad Z-45 Series Coverage — Fits multiple Z-45/25 and Z-45/22 variants, including IC Power, DC, Bi-Energy, and standard configurations.
- Restores Cylinder Integrity — A complete seal kit replaces all worn or weeping seals in one service interval, restoring the cylinder to proper operating condition and preventing fluid loss.
- Operational Safety — Maintaining sound cylinder seals is critical on articulating boom lifts, where cylinder performance directly affects platform positioning and safe operation at height.
A cylinder seal kit contains the full set of seals, O-rings, and wipers needed to rebuild a hydraulic cylinder. Over time, seals degrade from heat, pressure cycling, and contamination, causing the cylinder to weep fluid, lose holding force, or drift under load. Replacing the complete seal set — rather than individual seals — restores the cylinder to full working condition and extends service life. On an articulating boom lift, a cylinder that cannot hold position reliably creates a direct operational hazard, making timely seal replacement essential to keeping the machine working safely at height.
