Key Features
- Genuine OEM Construction — Manufactured to Genie's original dimensional and material specifications, delivering the same fit and grade as the part installed at the factory.
- Direct-Replacement Design — Engineered to install in place of the original ring gear with no rework required, keeping the repair straightforward and the machine back in service faster.
- Broad GTH Telehandler Coverage — Fits a wide range of Genie GTH telehandlers, including GTH-2506, GTH-3007, GTH-3512SX, GTH-4010SX, GTH-5519, GTH-3713 SX, and their regional and emissions-variant counterparts.
- Drivetrain Integrity — A ring gear in sound condition keeps rotational power transferred accurately and smoothly; a worn or damaged gear causes noise, rough engagement, and loss of drive performance.
A ring gear is a large toothed gear that meshes with a smaller drive gear or pinion to transfer and multiply rotational force within a drive assembly. It is a critical component in transmitting power through the drivetrain, and its tooth profile must be dimensionally accurate to ensure smooth, low-wear engagement with its mating gear. When a ring gear becomes worn, chipped, or cracked, it causes audible noise, vibration, and degraded drive performance — and continued operation with a damaged ring gear can accelerate wear on surrounding components. Replacing it with a correct OEM part restores proper mesh geometry and protects the integrity of the broader drive assembly.
