Show original supplier description
Utilizing a superior viscous damper design, this component is preferred by heavy-duty diesel OEMs for its effectiveness in smoothing engine operation. By mitigating these vibrations, the Fluidampr balancer helps to reduce wear on critical engine parts such as main bearings and timing gears, leading to increased longevity. Constructed from competition-built, precision CNC-machined, and balanced high-grade steel, this harmonic balancer features a corrosion-resistant black zinc finish with clearly engraved timing marks for easy setup. It is SFI 18.1 certified, ensuring it meets stringent safety standards for performance applications. The unit is designed for external engine balance and features a single 5mm keyway. Installation of this harmonic balancer can lead to several performance benefits, including improved engine timing, a reduction in the risk of crankshaft failure, and the potential to unleash lost torque and horsepower. Unlike some other components, the Fluidampr harmonic balancer requires no maintenance, offering a durable and reliable solution for performance diesel engine builders and enthusiasts. This harmonic balancer is specifically designed for 2001-2005 GM/Chevy vehicles equipped with the 6.6L Duramax LLY/LB7 engine. While a washer is included, a Fluidampr High Strength Bolt Kit (p/n 300010) is recommended for installation.
