OE 43512-42040 — Rotor Disc for Hyundai / Kia

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 brake system family — always confirm dimensions and connector layout before you swap.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded rotor disc transfers stress to neighbouring components, so a small repair can grow into a full brake system rebuild. Book the replacement once the symptom is repeatable.

Match three things: the code on the part you are removing, the build-year range in the Applications table, and the mounting points visible in the reference photo. If all three line up, 43512-42040 is a confirmed fit. Send your VIN and our export desk will double-check the ambiguous cases.

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

Aftermarket rotor disc 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.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 43512-42040 with other brake system references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.
