The Honda 31223-Z4M-003 Return Spring is a genuine OEM component designed for GX160 and GX200 horizontal shaft engines. Sourced directly from Honda, this return spring is an exact match for the original part, ensuring proper function without adaptation or guesswork. Confirm your engine's serial number against the fitment table before ordering, as Honda periodically supersedes parts at production breaks — part number 31223-Z4M-003 covers specific serial ranges within these two engine families.
Key Features
- Genuine Honda OEM — manufactured to Honda's original specification, delivering the correct spring rate and geometry for consistent mechanical return action in GX160 and GX200 engines.
- Direct Replacement — matches the original installation point exactly, so this spring drops in without rework or modification to surrounding components.
- GX160 and GX200 Fitment — designed specifically for GX160 and GX200 horizontal shaft engines; verify your serial number against the fitment table to confirm this is the correct part for your unit.
- Restore Proper Return Action — a worn or fatigued return spring fails to snap a mechanism back to its resting position cleanly, leading to sluggish or inconsistent response; replacing it restores crisp, repeatable operation.
A return spring provides the restoring force that pulls a lever, linkage, or control mechanism back to its default position once actuating pressure is released. In GX160 and GX200 horizontal shaft engines, this mechanical reset is essential to consistent throttle or governor response — without it, the linked component may hang mid-travel or fail to return fully, causing erratic engine behavior. Replacing a fatigued or broken return spring is a straightforward service step that restores the engine's control system to proper working order.
