Fluidampr Performance Diesel Damper (Harmonic Balancer/Crankshaft Pulley) 20-26 GM 6.6L Duramax L5P

The Fluidampr Performance Diesel Damper minimizes destructive torsional vibrations that occur each time your engine fires. Unlike factory rubber-based dampers that wear out and can't control vibrations across all RPMs, Fluidampr automatically adapts to your engine—even after modifications—delivering optimum damping at all frequency ranges.

By reducing torsional stress, this harmonic balancer protects your main bearings, crankshaft, and valvetrain from premature wear and failure. The result is enhanced engine longevity, more accurate valve timing, and improved reliability at any RPM—stock, work, or competition builds. Because it uses a fluid-based design instead of rubber, it outlasts the life of your truck while releasing lost torque and horsepower through superior vibration control.

Perfect for 20-26 GM 6.6L Duramax L5P engines..
