The Fluidampr Performance Diesel Series Damper 960311 will smooth out the harsh engine harmonics while extending the life of the engine in your 1989-1998 Dodge 12 Valve 5.9L Cummins or 3.9L Cummins 4BT. The factory damper on your diesel has a short lifespan and cannot control torsional vibrations at all RPMs. In contrast, Fluidampr offers superior performance that lasts for the life of your engine. It is ideal for all stock, work, and competition-built trucks, reducing wear on 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.

Fluidampr adapts to your modifications automatically, providing optimum damping at both peak levels and a broad changing frequency range. Precision CNC machined and computer-balanced components ensure the Fluidampr never needs to be rebuilt or tuned. Additionally, the Fluidampr design has been updated for ease of maintenance, eliminating the need to remove the damper to change your serpentine belt. Fluidampr manufactures this damper in the USA, and we take pride in our product.
