ATI Damper - 7.425In - Steel - 6 Grv - 17-19 GM Duramax

This ATI crankshaft damper measures 7.425 inches in diameter and is constructed from steel, featuring six grooves for accessory drive belts. It’s specifically designed for 2017 through 2019 model year GM trucks equipped with the Duramax engine. A crankshaft damper, also known as a harmonic balancer, is crucial for absorbing torsional vibrations generated by the engine's crankshaft. Without it, these vibrations can lead to premature wear and potential damage to the crankshaft and other engine components over time.

ATI is well-known for building robust engine components, and this damper is no exception. The steel construction offers a solid foundation for absorbing those harmful vibrations. The six-groove design means it can accommodate a full complement of accessory belts, ensuring all your engine's accessories—like the alternator, power steering pump, and air conditioning compressor—continue to function as intended. Proper dampening is especially important in high-torque diesel engines like the Duramax, where significant torsional forces are at play.

When you're working on a Duramax engine, especially one that might see heavy use or modifications, ensuring the crankshaft is properly protected is a top priority. This ATI damper is built to handle the demands of these engines, offering a reliable way to keep your crankshaft healthy and your accessories running smoothly. It’s a direct replacement part, meaning it’s designed to fit right into the factory location, simplifying the installation process.
