Protect your 2007.5+ Ram or Dodge 6.7L Cummins engine with the Fluidampr Performance Diesel Damper (Part #920321)—the same advanced viscous damper technology used by high-power diesel OEMs. Engine upgrades and increased horsepower can amplify destructive crankshaft torsional vibrations, leading to premature wear on key internal components. Installing a Fluidampr ensures smoother engine operation, reduced wear, and improved reliability under both stock and performance conditions.
Built with long-lasting viscous silicone and precision CNC-machined, computer-balanced steel components, the Fluidampr viscous damper continuously self-tunes across the entire RPM range for maximum vibration control. No tuning, adjustment, or maintenance is required—just consistent protection and durability for your Cummins engine.
