Fluidampr Performance Diesel Damper (Harmonic Balancer/Crankshaft Pulley) 17-19 GM 6.6L Duramax L5PWhy do you need a performance damper? First, let's explain why engines have a damper to begin with. Each time the air fuel mixture inside a cylinder is ignited, the combustion that occurs creates a torque spike that is applied to the crankshaft through the piston and rod. This torque spike is so severe that it not only turns the crankshaft, it actually twists the crankshaft ahead of its normal rotation and then the crankshaft rebounds. This twisting

Why do you need a performance damper? First, let's explain why engines have a damper to begin with. Each time the air/fuel mixture inside a cylinder is ignited, the combustion that occurs creates a torque spike that is applied to the crankshaft through the piston and rod. This torque spike is so severe that it not only turns the crankshaft, it actually twists the crankshaft ahead of its normal rotation and then the crankshaft rebounds. This twisting action is known as torsional vibration, and if it gets out of hand, it can cause damage. Dampers are designed to minimize these destructive vibrations.

Now, let's find out why the Fluidampr Performance Diesel Damper will do a much better job of protecting your engine than the factory stock damper. The factory rubber-based damper cannot control torsional vibrations at all RPMs, and the rubber doesn't last the life of the vehicle. On the other hand, Fluidampr automatically adapts to your engine, even when you make modifications, providing optimum damping at all frequency ranges, and because it isn't rubber-based, it will outlast the life of your truck.

The Fluidampr reduces wear on your main bearings and other vital engine components. This results in more accurate valvetrain operation, optimum engine protection at all RPMs, and a lower risk of crankshaft failure. A side benefit to vibration control is releasing lost torque and horsepower through greater efficiency. It's perfect for all stock, work, and competition-built trucks.

Is this a joke?
Color: Cream, Size: Large, Color: Cream, Size: Large
Is this a joke? I just opened a package that was sold as new, but nowhere on the purchase did it say it was refurbished or used. It looks obviously worn, yet it was sold to me as new. This should have been given to me for free. There are permanent stains on it and fresh hair all around the neck area, and I don’t have hair — I’m bald. Please see the pictures and my video. I just opened the pack, and it looked refolded and packaged as if fresh from someone else’s laundry.

Great Quality Shirt That Looks More Expensive
Color: Cream, Size: Medium
This is my 2nd COOFANDY purchase for my husbands wardrobe! Really impressed with this Knit Button Down Textured Polo Shirt. The material feels soft and breathable, and the textured design gives it a more elevated look than a basic polo. It fits well, looks great dressed up or casual, and is perfect for vacations, dinners, or summer events. Excellent quality for the price.
