The Genie 63344GT Cylinder Seal Kit is a genuine OEM kit designed for the S-80 and S-85 telescopic boom lifts. Sourced directly from Genie, this kit delivers the exact seals required for the S80 cylinder (63204), ensuring a correct, true-to-specification rebuild every time. Genuine OEM construction means every seal in the kit matches the original material grade, profile, and dimensional tolerances specified for these machines — no guesswork, no adaptation. Verify part number 63344GT against your S-80 or S-85 parts manual to confirm it corresponds to the correct cylinder assembly on your unit before ordering.
Key Features
- Genuine OEM Seal Materials — Each seal in the kit is manufactured to the same material grade and compression specification as the original, maintaining the integrity of the cylinder it services.
- Cylinder-Specific Kit — Engineered specifically for the S80 cylinder (63204) on Genie S-80 and S-85 boom lifts, so every seal installs directly into its intended groove without modification.
- Confirmed Fitment — Compatible with the Genie S-80 and S-85 telescopic boom lifts; cross-reference 63344GT against your machine's parts manual to confirm the correct cylinder application.
- Restored Cylinder Performance — Worn or damaged seals allow fluid to bypass the cylinder, causing slow, weak, or uncontrolled boom movement. A fresh seal kit restores full cylinder travel and consistent boom response.
- Operational Safety — On aerial boom lifts, a cylinder that cannot hold position is a serious safety concern. Replacing seals at the first sign of weeping or drift keeps the boom operating as intended and supports safe working at height.
A cylinder seal kit contains the full set of seals, O-rings, and wipers needed to rebuild a hydraulic cylinder back to its original condition. Over time, seals degrade from heat cycling, pressure, and normal wear, allowing fluid to leak past the piston or rod — resulting in cylinder drift, reduced lifting force, or visible weeping around the rod. Replacing all seals as a matched set, rather than individual pieces, ensures the rebuilt cylinder performs uniformly across its full range of motion. Using the correct OEM kit for the specific cylinder is essential, as seal profiles and materials vary between assemblies and machines.
