The Honda 31610-Z4T-843ZB Control Box Assembly (EXP-Alert) is a genuine OEM component designed for GX160 and GX200 horizontal shaft engines. As a direct-sourced Honda part, it carries the same specifications as the original unit and is the correct replacement when the existing control box requires service. Honda supersedes parts at serial-number breaks, so confirm your engine's serial number against the fitment table before ordering to ensure part number 31610-Z4T-843ZB is the right match for your unit.
Key Features
- Genuine OEM Construction — sourced directly from Honda, this control box assembly meets the same electrical and mechanical specifications as the original unit it replaces, with no guesswork on compatibility.
- EXP-Alert Variant — this assembly is the EXP-Alert configuration; match this designation to your engine's existing control box before purchasing, as alternate variants are not interchangeable.
- GX160 and GX200 Fitment — engineered specifically for Honda GX160 and GX200 horizontal shaft engines, covering a wide range of equipment applications these engines power.
- Serial Number Verification Recommended — Honda updates part specifications at production serial breaks; cross-reference your engine's serial number with the compatibility table to confirm this is the correct assembly for your engine.
- Electrical System Integrity — a failed or damaged control box can disrupt the alert and shutdown functions the engine relies on for protection; replacing it with the correct OEM assembly restores proper system operation.
The Control Box Assembly (EXP-Alert) is the central housing and wiring junction for the engine's alert and automatic shutdown system. It monitors operating conditions and triggers protective responses — such as low-oil shutoff — to prevent engine damage during normal use. When this assembly is damaged or fails, the engine's protective alert functions are compromised, leaving the engine vulnerable to conditions it would otherwise shut down to avoid.
