Is your factory harmonic balancer keeping up with the demands of your diesel engine? The Fluidampr Performance Diesel Series Damper is engineered to provide superior torsional vibration control for your 6.5L Diesel. Unlike conventional rubber dampers that deteriorate over time and only absorb vibrations within a narrow RPM range, Fluidampr's viscous design automatically adapts across the entire operating range, helping protect your engine whether it's stock, used for towing, or built for competition. By reducing harmful crankshaft harmonics, it promotes smoother engine operation, improved valvetrain accuracy, and longer component life.

Manufactured in the USA using precision CNC-machined, computer-balanced steel components, this maintenance-free damper is built to last the life of your engine without requiring tuning or rebuilding. The updated design also allows serpentine belt replacement without removing the damper, making future maintenance easier. Finished with a corrosion-resistant black zinc coating, it's built for everything from daily-driven work trucks to high-performance diesel builds.
