Product Number: 66057001
The Highway Automotive 66057001 is a 24-volt, 110-amp alternator engineered as a direct replacement for heavy-duty commercial vehicle applications, covering RVI and Volvo platforms across 19 verified fitments. Designed to restore reliable charging performance to high-demand diesel powertrains, it is suited to long-haul and fleet operators who require a dependable OE-specification replacement. The unit is supplied complete with belt pulley, featuring an 8-groove profile to match the serpentine drive arrangements found on the specified engines. At 24 V and 110 A output, it delivers the charging capacity demanded by the electrical systems of large-displacement commercial engines, including the Volvo D12 and D13 series and the Renault Trucks DXi 7, DXi 11, DXi 12, and DXi 13 families. Fitment spans the Volvo B12 coach range — including the B12, B12B, B12M, and B12R with TD122, TD123, D12A, and D12D engines — as well as the Volvo FH with D13 engine, and the RVI Magnum DXi range (440, 460, 480, 500) and the full RVI Premium 2 series from 240 to 460 bhp variants. This breadth of coverage makes the 66057001 a versatile stock holding for commercial vehicle workshops serving these platforms. Every Highway Automotive fitment is cross-referenced against manufacturer data and backed by the PartsForMachines Fit Guarantee. Returns are handled through our hassle-free returns policy should the part not be correct for your application.
