Key Features
- Genuine OEM Dimensional Accuracy — manufactured to Honda's exact thickness specification, which is the critical factor for any shimming application where stack height and clearance tolerances must be met
- Direct OEM Replacement — part number 90401-ZE2-620 drops in as a like-for-like replacement with no fitting adjustments needed beyond the shimming procedure itself
- Fits GX240 and GX270 Engines — listed for Honda GX240 and GX270 horizontal shaft engines; cross-reference your engine's serial number against the fitment table before ordering
- Serial Number Verification Recommended — Honda supersedes shim part numbers at production breaks, so always confirm your engine's serial number matches this listing before purchasing
A shim is a precision-thickness spacer used inside an engine to set or correct clearances between components — controlling end-play, preload, or alignment so that moving parts operate within their designed tolerances. When the correct shim is in place, components seat and move as Honda engineered them to; an incorrect thickness — even by a small margin — can result in excessive play, noise, premature wear, or improper component seating. Using the OEM-specified shim for your GX240 or GX270 engine ensures clearances remain within Honda's design envelope throughout the service life of the repair.
