As a direct OEM replacement, this collar is produced to the same specifications as the original part and installs in place of a worn or damaged unit without modification. Cross-reference part number 51.0811.4558GT against your GTH-1256 parts manual to confirm it is the correct item for your machine's boom assembly before ordering.
Key Features
- Genuine OEM Construction — Manufactured to original Genie specifications, ensuring correct dimensional fit and material grade for the GTH-1256 boom assembly.
- Direct OEM Replacement — Replaces the original 2nd Telescope Extension Cylinder Collar exactly, dropping into position without rework or adaptation.
- GTH-1256 Specific Fitment — Engineered specifically for the Genie GTH-1256 telehandler; confirm part number 51.0811.4558GT against your parts manual to ensure it matches your unit's build.
- Boom Function Integrity — A correctly fitted cylinder collar maintains proper alignment of the telescope extension cylinder within the boom, preserving smooth and controlled boom extension during operation.
A telescope extension cylinder collar locates and retains the cylinder within the boom structure, keeping it properly aligned as the boom extends and retracts. When this collar is worn, cracked, or missing, the cylinder can shift out of alignment, leading to uneven extension, accelerated wear on surrounding components, and reduced control during lifting operations. Replacing a damaged collar with a genuine OEM part restores proper cylinder positioning and helps protect the surrounding boom components from premature wear.
