Protect your Gen III HEMI car or SUV engine from harmful torsional vibration with a Fluidampr viscous damper designed for high-performance street and racing applications. Increased cylinder pressure, RPM and rotating assembly changes can reduce the effectiveness of stock elastomer-style dampers. Fluidampr viscous damping technology helps control crankshaft harmonics across the entire RPM range to support long-term engine durability, accessory drive stability and reduced wear on critical components.
