Fluidampr 17-19 GM 6.6L Duramax Steel Externally Balanced Damper

Fluidampr is known for building robust engine components that stand up to serious power. If you're working on a 2017-2019 GM truck with a 6.6L Duramax L5P engine, this steel externally balanced damper is designed to protect your investment. It controls harmful torsional vibrations across the entire RPM range, which can significantly reduce wear on critical engine parts like the crankshaft and help prevent failures.

This damper uses a viscous design that's been trusted by heavy-duty diesel OEMs and performance engine builders for over 35 years. It's precision CNC machined from high-grade steel and features a corrosion-resistant black zinc finish with an engraved timing mark for easy setup. The damper is SFI 18.1 certified, meaning it meets strict safety standards for racing applications, and it requires no maintenance. By controlling these vibrations, you can also see an improvement in timing accuracy, potentially unleashing lost torque and horsepower.

This damper is externally balanced and measures 8-3/8 inches in diameter, weighing 27.6 pounds. It also comes with pre-drilled 3/8-24 holes on a 3.2-inch bolt circle, which is useful if you plan to install custom drive mandrels. It's made in the USA and is a solid option for anyone looking to safeguard their powerful diesel engine.
