OE 43386-4B000 — Synchronizer Ring for Hyundai / Kia

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.

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

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 synchronizer ring the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

Noise normally traces to worn internal surfaces, a loose mount, a dry bearing or contact with a neighbouring part. Isolate it by reproducing the sound at a fixed speed, then compare against the reference photo for 43386-4B000 to confirm the right replacement.

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 engine & fuel system family — always confirm dimensions and connector layout before you swap.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 43386-4B000 with other engine & fuel system references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.
