How to Use the Part Finder

- Browse assemblies — Diagrams are grouped by system (Brakes, Engine, Electrical, etc.). Each diagram shows every part with its HD part number.
- Find alternatives — For each part, see availability, pricing, and aftermarket alternatives from brands like EBC, Galfer, and James Gaskets.
What Is an OEM Part Number?
An OEM (Original Equipment Manufacturer) part number is the unique reference assigned by Harley-Davidson to each component. These numbers appear in official service manuals, assembly diagrams, and dealer invoices. You can search the Part Finder by OEM number, manufacturer part number (e.g., EBC FA409V), or supplier SKU to find exact matches and compatible alternatives.
