Product Number: 66057005
The Highway Automotive 66057005 is a 24-volt, 120-amp alternator designed as a direct replacement for heavy-duty commercial vehicle applications. Supplied complete with belt pulley, it is built to restore reliable charging performance to Volvo trucks and is verified across seven specific vehicle and engine configurations. The unit operates at 24 V with a charging current of 120 A, making it suited to the high electrical demands of large diesel powertrains. The eight-groove belt pulley is included, allowing fitment without the need to source a separate drive component and keeping the installation process straightforward for workshop technicians. Fitment is confirmed for the Volvo FH, FH II, FM II, FMX III, and FH III, covering engine variants including the D11K and D13K — seven applications in total. Each fitment is backed by the PartsForMachines Fit Guarantee, giving added confidence when ordering. Country of manufacture: as stated in the product specification.
