OE 41551-604 — Pinion Gear for Hyundai / Kia

KingMay supplies OEM-grade aftermarket parts built to the 41551-604 factory specification: material grade, dimensional tolerance and surface finish follow the original tooling. They are not dealer-boxed genuine parts, and we quote them that way so there is no ambiguity at customs.

Bulk pricing is tiered: 10 pieces, 50 pieces and full-carton quantities each carry a different unit rate. Piece price also moves with packing format and whether your own brand is printed on the carton, so tell us the landed quantity you are planning.

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 41551-604 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.

The Related OE References table above lists the alternates we see most often in trade inquiries. Cross-references work because the engineering envelope is shared across the transmission & drivetrain family — always confirm dimensions and connector layout before you swap.

Aftermarket pinion gear 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.
