    Precision-Balanced Harmonic Balancers for Your Diesel Engine

    Fluidampr Performance Diesel Series Dampers are ideal for competition and owners who depend on their work truck. By installing a viscous damper, you will reduce wear on the main bearings and timing gear, achieve more accurate valvetrain operation and lower the risk of crank failure. Unlike rubber-based dampers, Fluidampr automatically adapts to your modifications, then continuously self-tunes in real time to optimum damping at both peak levels and across a broad changing frequency range.
