The Fluidampr 830141 Performance Diesel Damper will protect the engine from destructive crankshaft torsional vibration in your 2017-2019 GM 6.6L Duramax L5P. The factory damper on your diesel has a limited lifespan and cannot control torsional vibrations at all RPMs. On the other hand, Fluidampr offers superior performance that lasts the life of your engine. It is perfect for all stock, work, and competition-built trucks.
