The SM 7455 is a high-performance A/C compressor clutch pulley designed for the Tata Harrier (and Safari 2021+). While many Harrier models utilize Valeo units, certain production batches and specific regional variants are equipped with the Denso-type compressor architecture. This pulley is engineered to handle the massive 350Nm torque of the 2.0L Kryotec diesel engine, ensuring the A/C system engages smoothly without parasitic power loss or belt slippage.
