If you're working on the front end of your 2011-2016 Duramax LML or LGH diesel, especially if you're looking to replace a worn-out or damaged crankshaft damper, this ATI unit is a solid choice. This part is crucial for controlling torsional vibrations from the crankshaft, which helps protect your engine from damage and ensures smooth operation.

This ATI damper is constructed from steel for durability and features a 7.425-inch diameter.

When installing this damper, remember that it's a critical component for engine health. Ensure you have the proper tools for removal and installation, as it's typically a press-fit item onto the crankshaft snout. It's always a good idea to consult your vehicle's service manual for the correct procedures and any specific torque requirements. Replacing this part is a key step in maintaining the reliability and performance of your Duramax engine.
