Fluidampr Harmonic Dampers

Using only three parts (a laser-welded sealed housing, an internal inertia ring, and highly viscous silicone fluid between the two), SFI-approved Fluidampr harmonic dampers 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.

Innovators West Harmonic Balancers

Innovators West harmonic balancers are a great investment for your street or race vehicle. These dampers feature lightweight billet aluminum covers equipped with free-floating wet friction clutch pack assemblies that utilize spring-loaded inertia rings to dampen crankshaft harmonics over a wide rpm range. The rings work in conjunction with clutches to provide outstanding dampening action. That action does generate some heat, and Innovators West uses a small amount of fluid inside that acts as a lubricant, as well as dissipates heat to the outer body. Backed by over 25 years of experience, Innovators West has produced high-quality SFI 18.1 certified harmonic balancers employing all American-sourced materials and fasteners. Choose the model designed for your vehicle and engine application. Innovators West harmonic balancers/dampers feature: * Billet 6061 aluminum case for lower reciprocating weight * Fully scribed 360 degree timing marks * Laser-engraved part number and SFI rating on back * Premium steel internal inertia rings * Stress-proof steel crankshaft hub * OEM bolt pattern and pulley register
