Fluidampr Performance Viscous Damper for 1994-1999 Nissan Skyline R33 (RB25DET Non-NEO) - PN 610931

Fits 1994-1999 Nissan Skyline R33 (RB25DET Non-NEO).

Protect your engine's bottom end with the Fluidampr 610931 performance viscous damper. As engine modifications increase, the stock harmonic balancer can become inadequate at managing harmonic frequencies. This damper is engineered to control harmful torsional vibration across the entire RPM range, reducing the risk of crankshaft failure and premature wear on critical engine bearings and components. Unlike stock rubber-based balancers, Fluidampr’s viscous design provides continuous protection that doesn't degrade over time.

The unit is precision CNC machined from high-grade steel and finished in a corrosion-resistant black zinc coating. It features laser-engraved timing marks for accurate tuning and requires no ongoing maintenance or tuning. Trusted by professional engine builders, this damper ensures stable valvetrain timing and helps reclaim torque and horsepower lost to parasitic vibration.
