OE 55270-3S000 — Rear Lower Control Arm – Hyundai Sonata / Kia K5 Optima for Hyundai / Kia

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 suspension, steering & brake reference and narrow by build year. Send photos and we will cross-check the number for you.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded rear lower control arm – hyundai sonata / kia k5 optima transfers stress to neighbouring components, so a small repair can grow into a full suspension, steering & brake rebuild. Book the replacement once the symptom is repeatable.

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.

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.

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

Three checks: the code printed on your old part must read 55270-3S000; 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.
