Pulleys are components of the auxiliary drive belt system that transmit power from the crankshaft to the serpentine belt, and through it, to engine accessories – the alternator, power steering pump, air conditioning compressor, or water pump. We distinguish between the crankshaft pulley (often with a torsional vibration damper) and accessory pulleys, including the alternator pulley with a one-way clutch. Properly functioning pulleys have a direct impact on the smooth operation of the accessory drive and the overall engine's refinement.

A worn pulley exhibits characteristic symptoms: knocking, rattling, or humming from under the hood, vibrations and wobbling of the belt, squealing of the auxiliary belt, and in the case of a delaminated vibration damper – noticeable engine vibrations. A damaged one-way clutch in the alternator pulley causes noise and accelerates belt wear. A component left without replacement accelerates the wear of the belt and tensioner and risks its rupture, which is why a worn pulley should be replaced with a new substitute.

In this collection, you will find accessory drive pulleys – crankshaft pulleys, torsional vibration dampers, and alternator pulleys – suitable for popular makes and models of passenger cars and light commercial vehicles. We offer replacements from proven manufacturers that match the quality and durability of factory-installed parts. In our store, you can also complete your accessory drive system with other components that work with pulleys, such as the serpentine belt, tensioner, and accessory belt idlers.

Each pulley must be matched to a specific car model and engine version – before purchasing, it is worth verifying the part number to choose the correct replacement. Pulleys are best replaced together with the belt and accessory tensioner as a complete set. We offer pulleys at competitive prices, with fast delivery.
