Detailed Product Description

BBB Industries N8315 is a replacement alternator engineered around Ford charging-system specifications. It uses a 6-groove serpentine pulley, a 2-3/8 inch (61 mm) outside pulley diameter, and a plug clock position of 10 to match the listed applications. The internal regulator and air-cooled, internally fan-cooled layout support stable electrical output in vehicles that rely on a factory-style alternator configuration.
