The SM 7443 is a high-specification A/C compressor clutch pulley engineered specifically for the luxury and safety standards of the Volvo passenger vehicle lineup. Designed to fit the high-output compressors found in Volvo’s Drive-E (VEA) and D-series diesel engines, this pulley is built to manage the high thermal loads of turbocharged/supercharged engines while maintaining the ultra-refined cabin acoustics expected of the brand.
