Replace the out-of-balance damper on your 2011-2016 GM 6.6L Duramax LML/LGH with a superior quality Fluidampr Performance Diesel Series Damper 830121. The factory damper on your diesel has a limited lifespan and fails to control torsional vibrations at all RPMs. In contrast, the Fluidampr offers superior performance that endures for the life of your engine. It is suitable for all stock, work, and competition-built trucks, and it reduces wear on your main bearings and other vital engine components. This results in more precise valvetrain operation, optimum engine protection at all RPMs, and a lower risk of crankshaft failure.

The Fluidampr automatically adjusts to your modifications, providing optimal damping at both peak levels and a wide range of frequency changes. It is made with precision CNC machined and computer-balanced components, and it never needs to be rebuilt or tuned. The Fluidampr design has been updated for ease of maintenance, so you no longer have to remove the damper to change your serpentine belt. Fluidampr takes pride in manufacturing this damper in the USA.
