The Honda 16555-ZN2-000 Governor Rod is a genuine OEM component designed for GX620 and GX670 horizontal shaft engines and GXV610, GXV620, and GXV670 vertical shaft engines. As a direct Honda OEM part, it matches the original specification exactly, giving you the correct geometry and linkage travel your governor system relies on. Verify your engine's serial number against the fitment table before ordering, as Honda supersedes components at specific serial breaks across these engine families.
Key Features
- Genuine OEM Linkage Geometry — manufactured by Honda to the original rod length and bend profile that keeps governor response accurate across the full RPM range
- Direct OEM Replacement — connects into the existing governor linkage without modification, restoring the mechanical relationship between the governor arm and throttle exactly as designed
- Broad Engine Compatibility — fits GX620 and GX670 horizontal shaft engines and GXV610, GXV620, and GXV670 vertical shaft engines, covering Honda's large-displacement V-twin lineup
- Serial Number Verification Recommended — Honda updates governor linkage components at production serial breaks; confirm your engine's serial number against the compatibility table to ensure this rod is correct for your unit
- Speed Stability Under Load — a bent, worn, or missing governor rod allows engine speed to hunt or surge under load; replacing it restores stable, consistent governed RPM
The governor rod is a rigid mechanical link within the engine's mechanical governor system. It transfers motion between the governor arm — which responds to centrifugal force from the flywheel governor weights — and the throttle linkage, allowing the engine to automatically correct its speed when load increases or decreases. When the rod is bent, corroded, or out of position, the governor loop loses its precise range of travel, causing the engine to surge, hunt, or fail to hold its set speed under varying loads. Replacing a damaged rod with the correct OEM part is essential to restoring stable governed operation.
