Key Features

• Genuine OEM Sealing Materials — Manufactured to Genie's original material and dimensional specifications, this kit delivers the compression and sealing performance cylinder 55717GT requires.
• Exact Cylinder Match — Engineered specifically for cylinder 55717GT, the seals, wipers, and o-rings in this kit seat correctly without modification or adaptation.
• Broad GS Series Compatibility — Fits Genie GS-2632, GS-2646, GS-2668 RT, GS-3268 RT, GS-2668 DC, and GS-3268 DC scissor lifts, covering both standard and rough-terrain variants.
• Restores Cylinder Integrity — A worn or leaking cylinder seal allows fluid bypass, causing slow, weak, or uneven lift performance. Replacing seals with this OEM kit restores full cylinder function.
• Aerial Work Platform Safety — Cylinder sealing integrity is directly tied to platform stability and lift capacity on scissor lifts. Using the correct OEM seal kit keeps the lift performing as designed.

A cylinder seal kit contains the seals, o-rings, and wipers that prevent fluid from bypassing the piston or escaping past the cylinder rod on a lift cylinder. Over time, seals degrade from heat, pressure cycles, and contamination, leading to internal or external fluid leaks that reduce lifting force and cause the platform to drift or fail to hold position. Replacing the seals in cylinder 55717GT with the correct kit — Genie part number 78912GT — restores a tight, leak-free cylinder and brings lift performance back to its original specification.
