The Genie 88451GT is a genuine OEM Throttle Actuator (Bosch) designed for a wide range of Genie telescopic boom lifts, articulating boom lifts, and GS scissor lifts. Sourced directly from the OEM supply chain, this actuator is the correct replacement for machines including the S-40, S-45, S-60, S-65, S-80, S-85, and their XC, TRAX, HC, HF, and XC variants, as well as Z-series articulating booms such as the Z-45/25, Z-45/25J IC Power, Z-60/34, Z-62/40, and Z-80/60, and GS scissor models including the GS-3384, GS-3390, GS-4390, and GS-5390. Cross-reference part number 88451GT against your Genie parts manual to confirm fitment for your specific machine serial range. As a genuine OEM component, this actuator meets the same design and performance standards as the part originally installed at the factory.
Key Features
- OEM-Spec Throttle Control — Engineered to deliver precise, repeatable throttle positioning, ensuring the engine responds correctly to operator inputs across the full RPM range.
- Bosch-Sourced Component — This actuator is supplied by Bosch, the same manufacturer used in original production, so electrical connections, response characteristics, and mounting geometry match what came off the line.
- Broad Model Coverage — Fits Genie S-series telescopic booms, Z-series articulating booms, and GS large-frame scissor lifts — one part serving multiple machine families in a single fleet.
- Direct Drop-In Replacement — Designed to install in the same location as the original actuator with matching connector pinout and mounting interface, keeping the job straightforward.
- Restores Engine Response & Drive Performance — A worn or failed throttle actuator causes erratic engine speed, sluggish drive, and unpredictable platform movement; replacing it restores consistent power delivery and predictable machine behavior.
- Critical for Safe Elevated Operation — Proper throttle control is directly tied to stable platform movement and boom function at height — a correctly functioning actuator is essential for safe, controlled operation on Genie aerial equipment.
The throttle actuator is an electromechanical device that translates electronic control signals from the machine's engine control system into precise mechanical movement of the engine throttle. On Genie boom lifts and scissor lifts, this component governs engine speed in response to operator demand — controlling drive speed, lift speed, and auxiliary hydraulic functions. When the actuator begins to fail, operators typically experience hunting or surging engine RPM, sluggish or unresponsive drive, and inconsistent lift performance; in severe cases the engine may not rev beyond idle, rendering the machine inoperable at height. Replacing the actuator with a genuine OEM unit restores the calibrated response the machine's control system expects.
