ACDelco Engine Crankshaft Pulley 55512109

GM Genuine Parts Engine Crankshaft Pulleys are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These pulleys attach to, and are driven by, the front of the engine crankshaft. They connect to various engine accessory drive components by a belt drive system and help ensure that components, such as the water pump, alternator, and power steering pump, receive power from the rotating crankshaft to perform their vital functions. Crankshaft pulleys also work as harmonic dampers to help decrease crankshaft torsional vibration. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
