Designed just for mildly built small block Chevys, the Streetdampr harmonic dampers use silicone fluid in a sealed laser-welded housing to control crankshaft vibration at all engine rpms, just like their race-ready brothers. That means more accurate spark and valve timing, and reduced bearing and valvetrain wear. About the only difference between the Streetdamprs and Fluidamprs is that the Streetdamprs aren't SFI-approved for racing--well, that, and their lower price tag.
