OE 81780-D3100 — Electric tailgate strut assembly for Hyundai / Kia

Incoming batches pass a dimensional check, a material look-up against the body & interior specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

Three checks: the code printed on your old part must read 81780-D3100; the number must fall inside the build-year range in the Applications table; and the connector, thread or bolt pattern must match the reference photo. Codes cast into the housing are the most reliable source.

Stock references leave Guangzhou within 7 working days. If 81780-D3100 needs a production run, allow 25-35 days depending on quantity and surface treatment. The schedule is confirmed in writing when the order is placed.

Four variables explain most of the spread: material grade, whether the goods are new production or clearance stock, packing format, and whether the quote is ex-works or landed. Ask for the material certificate alongside the price — that is what makes a comparison like-for-like.

Aftermarket electric tailgate strut assembly 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.

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 body & interior family — always confirm dimensions and connector layout before you swap.
