Moroso cast aluminum crankshaft pulleys have a small diameter that slows fan, water pump, and alternator speeds to reduce horsepower-robbing drag. They also have extra-deep grooves to provide added belt retention during rapid changes in engine rpm. They are precision-machined from high-grade, lightweight, aluminum castings.
