The Genie 51139GT is a genuine OEM Extension Roller Pin built for Genie GS-2668 RT, GS-3268 RT, GS-2668 DC, and GS-3268 DC rough-terrain and electric scissor lifts.

Verify part number 51139GT against your machine's parts manual to confirm it is the correct pin for your serial number and configuration.
Key Features
- Genuine OEM Construction — Manufactured to exact dimensional tolerances, ensuring correct fit within the extension roller assembly without rework or shimming.
- Direct OEM Replacement — Drops into the original pin location on the scissor extension deck, retaining the factory mounting geometry.
- Broad GS Series Compatibility — Fits GS-2668 RT, GS-3268 RT, GS-2668 DC, and GS-3268 DC scissor lifts, covering both rough-terrain and electric-drive variants.
- Smooth Roller Operation — A correctly fitted pin allows the extension roller to travel freely, keeping deck extension and retraction consistent under load.
- Operational Safety — A worn or missing roller pin can cause the extension deck to bind, shift, or fail to seat correctly — replacing it promptly keeps the platform behaving as designed on aerial lifts where deck stability is critical.
The extension roller pin is the pivot point that holds the roller in position as the scissor lift's extension deck slides in and out. The roller reduces friction between the moving deck and its guide surfaces, allowing smooth, controlled travel. When the pin wears, becomes bent, or works loose, the roller can seize or shift out of alignment, causing the deck to drag, bind, or move unevenly — conditions that put stress on surrounding components and affect platform stability for the operator.
