Fluidampr 830151 Harmonic Balancer for 2020+ GM Duramax L5P Diesel

The Fluidampr 830151 is a high-performance viscous harmonic balancer engineered specifically for 2020 and newer GM/Chevy Duramax L5P diesel engines. When serious power modifications are on the table, this damper provides critical protection against destructive torsional vibration that can lead to crankshaft failure.

Superior Viscous Damping Technology:

• Controls harmful torsional vibration across the entire RPM range, not just at specific frequencies like elastomer dampers
• Utilizes proven viscous fluid technology preferred by heavy-duty diesel OEMs
• Reduces wear on engine bearings, timing components, and drivetrain parts
• Helps unleash lost torque and horsepower by reducing parasitic losses
• Improves ignition timing accuracy and consistency

Premium Construction:

• Precision CNC-machined from high-grade steel components
• Competition-built quality with precision balancing
• Durable black zinc finish provides superior corrosion resistance
• Laser-engraved timing marks for accuracy
• SFI 18.1 certified for performance and racing applications
• Maintenance-free design - no rebuilds or servicing required

Trusted by leading performance diesel engine builders worldwide, this American-made harmonic balancer is the ultimate upgrade for modified Duramax L5P engines producing increased power and torque. Essential protection for trucks used in towing, racing, or high-performance street applications.
