Overview

PRW Pro Series SFI-Rated Harmonic Dampers

PRW Power Pro Series SFI-rated harmonic dampers are high performance engine parts designed to control torsional vibration (twisting forces on the crankshaft) and protect rotating assemblies in high-RPM street and race engines.

Key features and construction:

* Billet steel forgings: Both the inner hub and outer inertia ring are built from high-grade billet carbon steel
* Injected elastomer: A specialized rubber elastomer is injected between the hub and ring under heat, using inner and outer ridgelines to lock the components tightly together
* SFI 18.1 certification: They meet strict SFI 18.1 safety specifications required for competitive racing and high-stress environments
* Precision markings: Dampers feature easy-to-read, laser-engraved timing marks and precise crank bores for a secure pressed fit

* Purpose and benefits:
-- Vibration control: Reduces harmful engine harmonics and parasitic power loss
-- Component protection: Prevents potential crankshaft fatigue or failure under heavy horsepower and high-RPM loads
-- Versatility: Suited for weekend track cars, high performance street builds, and dedicated competition engines
