Audi Seat Belt Retractor (OEM 423857705B) — a used genuine front left retractor from an R8 donor. Also known as a seatbelt retractor, this safety component controls webbing payout and locking during sudden stops. Common symptoms of a worn retractor include sagging belt, slow retraction, or failure to lock in a collision. As a safety part, installation must be performed by a qualified technician. Designed for the R8’s 4.2L V8 or 5.2L V10, this OEM retractor restores proper restraint function.
