The Fluidampr Performance Diesel Series Damper 890101 is an excellent way to smooth out the engine while adding a few ponies to your 2001-2005 GM 6.6L Duramax LB7 & LLY. The factory damper on your diesel has a limited lifespan and does not effectively control torsional vibrations across all RPMs. However, Fluidampr provides superior performance that lasts for the entire life of your engine. It is ideal for all types of trucks, including stock, work, and competition-built ones. By reducing wear on your main bearings and other vital engine components, Fluidampr ensures more accurate valvetrain operation, optimum engine protection at all RPMs, and reduces the risk of crankshaft failure.

Fluidampr is different from the factory rubber-based damper as it automatically adapts to your modifications, providing optimal damping at both peak levels and a broad changing frequency range. Its components are precision CNC machined and computer-balanced, ensuring that the Fluidampr does not need to be rebuilt or tuned. The Fluidampr design has been updated for ease of maintenance, allowing you to change your serpentine belt without removing the damper. Fluidampr is proud to manufacture this damper in the USA.
