Fluidampr Performance Diesel Damper (Harmonic Balancer/Crankshaft Pulley) 20-23 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.

Metal tab blocks magnetic charging
The set screws are too small and they do not have an adapter that fits the magnet charging rings on the newer phones

My favorite BMW car mount.
This is my favorite mount for BMWs. I have them on two cars (X4M and a 328), but I always modify the mount and install a metal ball (purchased here on Amazon) so I can mount an ESR Wireless charger. This combo is the best charging mount and system I have ever tried

sturdy mount nice fit
fit nicely and magnet is strong using the included metal disc to put inside phone case. was missing instructions but figured it out. you have to screw in the small set screws until it is snug. using a longer hex key made it easier.
