The used OEM BMW seat belt retractor (OEM 3448363, also replaces 3400817) is a genuine safety component removed from a donor vehicle. This left rear retractor serves the critical function of locking the belt during sudden stops or impacts. Common failures include sluggish or incomplete retraction, or the belt not locking when pulled sharply. This part is designed for the BMW X3 equipped with the 2.5L or 3.0L I6 naturally aspirated engine. As a safety part, installation should be performed by a qualified technician to ensure proper function and occupant protection.
