    The use of a worn or damaged viscous damper will lead to catastrophic engine failure. This had happened to many owner-operators when this item was overlooked while completing an in-frame overhaul. Replacing the vibration damper will not fix wear or undue neglect of the proper maintenance protocols of the engine components. Vibratech does not recommend or endorse re-using viscous dampers.

  • Part Number715285-000
  • Manufacturer: Vibratech TVD
  • Product NoteKLM Performance recommends regular damper inspection along with replacing your crank damper every 300 to 500 thousand miles. Regular inspection and replacement of the engine's damper prevent the extreme costs incurred when you break your crankshaft or the other problems caused by deteriorating damper function. Think about purchasing a new heavy duty crankshaft damper as an insurance policy against a future broken crankshaft and you will feel the engine run smoother.
