OE 45621-4G500 — Piston Lower Reverse Brake for Hyundai

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 45621-4G500 to confirm the right replacement.

Build-year coverage is listed row by row in the Applications table above. Where several generations share one number, the newer rows usually carry a revised suffix — compare the last four characters before buying, since a suffix change often means a different connector or bracket.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 45621-4G500 with other brake system references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.

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.

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.

Three checks: the code printed on your old part must read 45621-4G500; 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.
