The SM 7433 is a heavy-duty A/C compressor clutch pulley specifically designed for Chevrolet’s premium diesel lineup. This pulley is engineered for the Valeo-type (VAL.TYPE) compressor architecture found in the 2.0L VCDi turbocharged diesel engines. Given the high torque and significant engine bay heat generated by these powerplants, the SM 7433 is built to exceed standard OE specifications for durability and thermal resistance.
