The SM 7447 is a heavy-duty A/C compressor clutch pulley specifically designed for the Maruti Suzuki Super Carry commercial vehicle. This pulley is engineered for the Denso-type compressor architecture found in both the petrol and S-CNG variants. Given that the Super Carry is a commercial workhorse often subjected to long idling hours and heavy engine loads, the SM 7447 is built for maximum durability and thermal resistance.
