The Fluidampr 830151 Performance Diesel Damper can help prevent the engine from damaging torsional vibration of the crankshaft in your 2020-2023 GM 6.6L Duramax L5P. The factory damper on your diesel has a limited lifespan and does not control torsional vibrations at all RPMs. In contrast, Fluidampr offers superior performance that lasts for the life of your engine. It is suitable for all stock, work, and competition-built trucks, reducing wear on your main bearings and other vital engine components. This provides you with more accurate valvetrain operation, optimum engine protection at all RPMs, and lowers the risk of crankshaft failure.

Unlike the factory rubber-based damper, Fluidampr automatically adapts to your modifications, providing optimum damping at both peak levels and a broad changing frequency range. The Fluidampr features precision CNC machined and computer-balanced components, ensuring it never needs to be rebuilt or tuned. Additionally, the Fluidampr design has been updated for easy maintenance, with no need to remove the damper to change your serpentine belt. Fluidampr takes pride in manufacturing this damper in the USA.
