OE 23124-03HA0 — Crangshaft pulley for Hyundai / Kia

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, 23124-03HA0 is a confirmed fit. Send your VIN and our export desk will double-check the ambiguous cases.

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.

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

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.

Report it with the order number and packing-list line plus photographs. Because every carton is photographed before loading, we can trace the batch immediately and settle the claim against the inspection record instead of arguing from memory.

A supersession happens when the maker revises a crangshaft pulley 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 23124-03HA0 we list the current reference; ask our desk for written confirmation before a large order.
