Your stock crank damper can wear down over time, especially as you add performance to your 2001-2005 Duramax-powered truck. That wear can let the vibrations of your crankshaft work their way through the engine leading to wear on main bearings and timing gear.
By installing a Fluidampr 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, the Duramax fluid damper 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.
Features precision machined and computer balanced components. It never needs to be tuned or rebuilt. The official damper of the NADM. SFI Approved. Made 100% in the U.S.A. ISO Certified.
