Fluidampr Internal Chrysler 318, 340 & 360 CID V-8 A/LA Steel Black Zinc O.D. 7-1/4" 720301

Using only three parts--a laser-welded sealed housing, an internal inertia ring, and highly viscous silicone fluid between the two--these SFI-approved Fluidamprs can control all crankshaft vibration, not just a limited frequency range. As a result, you get reduced wear on the main bearings and timing gear, more stable valvetrain operation, and less chance of crank failure.
