The Fluidampr Performance Diesel Series Damper 830111 will reduce damaging engine harmonics in your 2006-2010 GM 6.6L Duramax LLY/LBZ/LMM truck. The factory damper on your diesel has a limited lifespan and cannot control torsional vibrations at all RPMs. In contrast, the Fluidampr offers superior performance that lasts the lifetime of your engine. It is suitable for all stock, work, and competition-built trucks. The Fluidampr reduces wear on your main bearings and other vital engine components, providing more accurate valvetrain operation and optimum engine protection at all RPMs. The risk of crankshaft failure is also reduced.

Unlike the factory rubber-based damper, the 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, eliminating the need for rebuilding or tuning. 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 is proud to manufacture this damper in the USA.
