As a Honda OEM component, this E-Ring (2mm) is produced to the same specifications as the original hardware and is an exact match for the application.

Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this retaining ring matches the original in size, gauge, and retention geometry for a true like-for-like swap.
- Correct 2mm Sizing — the 2mm designation is the critical spec; using an incorrectly sized E-ring can allow components to shift or come free, so confirm this matches your application.
- Broad Honda Fitment — listed for GX390 horizontal shaft engines and the EB3800, EB5000, EB6500, EM3800, EM5000, and EM6500 generators; check your serial number against the fitment table to verify.
An E-ring is a small open-ended retaining ring shaped like the letter "E" that snaps into a groove on a shaft or pin to hold an adjacent component in its axial position. It functions as a compact alternative to a traditional snap ring and is widely used throughout Honda engines and generators to secure linkage pins, pivot points, and other shaft-mounted components. When an E-ring is missing, damaged, or the wrong size, the part it retains can shift or disengage, leading to erratic operation or component damage.
