Key Features
- Genuine OEM Quality — Manufactured to original equipment specifications for dimensional conformity and material grade, ensuring this piston performs exactly as the factory-installed component did.
- Direct OEM Replacement — Engineered to install in place of the original without modification, maintaining correct bore clearances and sealing surfaces critical to proper function.
- Broad GTH Telehandler Fitment — Compatible with multiple GTH-3007 and GTH-3512 variants, including AU, AU-AG, FMS, ACF configurations, and the GTH-3713 AU.
- Restored Component Integrity — A worn or damaged piston compromises the output and control of the assembly it serves; replacing it with this genuine part restores proper operation and extends service life.
- Part Number Confidence — Always cross-reference 639815GT against your Genie parts manual to confirm fitment for your specific machine configuration and serial number range.
A piston transfers force within a cylinder, converting fluid pressure into linear mechanical movement. It must maintain a precise fit within the cylinder bore to sustain pressure and deliver consistent, controlled motion. When a piston wears, becomes scored, or loses its sealing integrity, the assembly it serves loses efficiency, responds sluggishly, or fails to hold position under load — all of which affect machine control and productivity. Replacing a worn piston with this genuine OEM part restores the correct bore-to-wall clearance and ensures the cylinder operates as intended across the GTH telehandler models this component is built for.
