The Genie 634391GT is a genuine OEM Thickness Shim designed for Genie GTH-series telehandlers, including the GTH-2506, GTH-3007, and GTH-5519. As a direct OEM replacement, this shim is manufactured to the exact tolerances required to maintain proper component alignment and clearance across the GTH telehandler line. This part covers a wide range of GTH variants — including AU, AU.2, AU.3, AU-AG, ACF, FMS, and S configurations — making it a dependable solution for fleet maintenance operations running multiple GTH models.
Key Features
- Exact OEM Tolerancing — Manufactured to Genie's precise thickness specification, ensuring correct clearance and load distribution at the installation point — no guesswork, no shimming adjustments.
- Direct Drop-In Replacement — Engineered to install exactly where the original shim seated, maintaining the correct stack height and component positioning without additional machining or fitting.
- Broad GTH Telehandler Coverage — Fits the GTH-2506, GTH-3007, and GTH-5519 across multiple regional and configuration variants, including AU, AU.2, AU.3, AU-AG, ACF, FMS, and S models.
- Structural Alignment Integrity — A correctly specified shim prevents uneven load transfer and premature wear on adjacent components; an incorrect thickness or worn shim can introduce play that accelerates damage to surrounding assemblies.
- Operational Safety on Heavy-Lift Equipment — On telehandlers operating at rated capacity, proper shim fitment is critical to maintaining structural integrity at load-bearing joints and pivot points — making specification accuracy a genuine safety consideration.
A thickness shim is a precisely machined spacer used to set or restore the correct gap, alignment, or preload between two mating components — typically at pivot points, axle assemblies, boom mounting interfaces, or drive train connections. On GTH telehandlers, shims play an important role in ensuring that structural and mechanical assemblies operate within their designed tolerances. When a shim wears, compresses, or is lost during service, the resulting play or misalignment can cause accelerated wear on surrounding components, introduce unwanted movement in load-bearing joints, or affect the machine's ability to handle loads safely. Replacing it with a genuine OEM shim of the correct thickness restores the assembly to its original specification.
