Why do I need to change my 6.7L Cummins Damper when I already have a viscous damper on my diesel engine?
The 6.7 Liter Cummins is a very popular engine to modify and use for competition purposes or increased power output levels. Straight from the factory, your engine is equipped with a viscous damper. Cummins developed the 6.7L turbo diesel with many advanced features that were designed for stock power levels only. When power is added to your 6.7L engine you exceed the performance levels of the OEM viscous damper. Fluidampr invented the Viscous crankshaft damper and they are well aware that high performance engines require a precision-made product to control torsional vibrations. Only a viscous damper can control torsional vibrations at all power levels and engine RPMs. The Fluidampr 920321 Performance Diesel damper provides optimum protection under the extremes of professional diesel drag racing and sled pulling.
