OE 23410-2G921 — Piston Pin ASSY for Hyundai

Aftermarket piston pin assy comes from tooling houses that hold the original drawings or licensed equivalents. KingMay sources from vetted factories and inspects each batch; the manufacturer name is available on request where your market requires origin documentation.

Build-year coverage is listed row by row in the Applications table above. Where several generations share one number, the newer rows usually carry a revised suffix — compare the last four characters before buying, since a suffix change often means a different connector or bracket.

Every shipment of 23410-2G921 leaves with a packing list, photo documentation and a QC report. Warranty terms are agreed per contract and reference that inspection record; claims are settled in writing against the documentation.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a piston pin assy the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

A supersession happens when the maker revises a piston pin assy and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 23410-2G921 we list the current reference; ask our desk for written confirmation before a large order.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.
