Fluidampr 11-17 GM Harmonic Balancer | 830111 | 2011-2017 GM Duramax LML / LGH

Protect your truck with the technology high power diesel OEMs use. A Fluidampr performance diesel damper provides premium, broad range control of destructive crankshaft torsional vibration for optimum performance and durability. Install Fluidampr to reduce wear on critical internal engine components when engine modifications are done to gain horsepower or when rotating assembly parts are upgraded. Features high quality, long lasting viscous silicone with precision CNC machined and computer balanced high-grade steel components. No tuning or maintenance required.

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. When these torque spikes and forces get into phase with the natural frequency, critical torsional harmonic vibrations occur and can be seriously destructive to the bearings and the crankshaft. Dampers are designed to control those destructive vibrations.
