The SM 7405 is a high-performance A/C compressor clutch pulley specifically engineered for the Hyundai Verna (Fluidic and Next-Gen models). This pulley is designed for the Valeo-type (VAL.TYPE) compressor architecture, which is common in Hyundai's diesel and petrol variants. Unlike Denso units, Valeo compressors require a specific bearing offset and a precision-machined friction face to ensure smooth engagement with the Valeo clutch plate.
