Audi harmonic balancer / crankshaft / crank pulley, part number 079105251AP, is a used genuine OEM component removed from a donor vehicle. This pulley, also called the crank pulley or harmonic damper, mounts to the front of the crankshaft on the 4.0L turbo V8 (3993cc). It drives the serpentine belt and absorbs crankshaft vibrations. A failing balancer can cause belt noise, wobble, or visible separation of the rubber ring—common on high-mileage units.
