OE 48609-42020 — Strut Mount for Hyundai / Kia

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.

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 engine & fuel system family — always confirm dimensions and connector layout before you swap.

Watch for noise on cold start, vibration under load, warning lights, fluid seepage or uneven operation. Once any of those appears the strut mount should be inspected, and reference 48609-42020 replaced if it measures outside specification.

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

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 engine & fuel system 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.
