The SM 7423 is a premium-grade A/C compressor clutch pulley specifically designed for the Skoda Superb (and select high-end Volkswagen Group vehicles). This pulley is engineered for the Valeo-type (VAL.TYPE) compressor architecture, which is frequently found in the 2.0L TDI (Diesel) and 1.8L/2.0L TSI (Petrol) variants of the Superb. It is built to meet the high-torque demands and refined acoustic standards of Skoda's flagship luxury sedan.
