This 24V 90A 7PK80 alternator is engineered for high-demand applications on ISUZU FSR90 and Forward series trucks equipped with the 4HK1-TC turbocharged diesel engine. With a robust 90-amp output—among the highest in the medium-duty segment—it reliably supports complex electrical architectures, including engine control modules, ABS/ESC systems, multi-zone climate control, liftgate hydraulics, refrigeration units, and advanced driver assistance systems (ADAS), even under prolonged idle or low-RPM operation.
The unit features a precisely balanced 7PK pulley (80mm diameter) designed to match ISUZU’s original serpentine belt routing and tension specifications. This ensures minimal belt wear, reduced driveline vibration, and stable performance across 0–5,000 RPM operating ranges—critical for urban delivery, utility, and refrigerated transport cycles.
