Why Choose Vibratech 718041-600 for Your Cummins QSX Engine?

The Vibratech TVD 718041-600 is built with advanced engineering and designed to last longer than conventional dampers. Unlike lower-quality overseas alternatives, this USA-manufactured vibration damper provides:

• Better durability in extreme operating environments
• Stronger crankshaft protection against premature wear
• Proven vibration control technology trusted in heavy-duty diesel applications
• Precision balancing for optimal engine performance

This is not an OEM Cummins part but a direct OE replacement engineered for superior reliability and performance.

NOTE: Vibratech leaves their precision dampers unpainted to maintain perfect balance, improve heat dissipation, prevent flaking, and preserve OEM‑grade performance. The Viscous crankshaft damper converts torsional vibration into heat. They rely on the steel housing to shed that heat efficiently. Paint acts as an insulator, which can trap heat and reduce long‑term performance. Leaving the damper unpainted ensures maximum thermal dissipation.

• Product Note: The Torsional Vibration Damper on your Cummins QSX is a wear item that requires replacement at the 500,000-mile mark.  The installation of a new Damper is strongly recommended in an effort to eliminate harmful torsional crankshaft vibration and ensure trouble-free operation. The replacement of the engine crankshaft damper is often overlooked during the In-Frame overhaul process due to costs. We at KLM Performance come across two different types of customers the ones who choose to purchase a replacement viscous crankshaft damper and the ones who wish they had. The second customer is the one now dealing with a damaged crankshaft and other serious engine failures.
