OE 41521-611 — Side Gear 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, 41521-611 is a confirmed fit. Send your VIN and our export desk will double-check the ambiguous cases.

A supersession happens when the maker revises a side gear 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 41521-611 we list the current reference; ask our desk for written confirmation before a large order.

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.

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest transmission & drivetrain reference and narrow by build year. Send photos and we will cross-check the number for you.

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.

Three checks: the code printed on your old part must read 41521-611; 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.
