Fluidampr Chevy 454-502 CID-V8 w/ (2) 1/4 key slots Steel Externally Balanced Damper 800121

Normal stock damper wear and engine performance upgrades increase the naturally occurring characteristics of harmful crankshaft torsional vibrations. By installing a Fluidampr viscous damper you will reduce wear on the main bearings and timing gear, achieve more accurate valvetrain operation and lower the risk of crank failure. Unlike rubber based dampers, Fluidampr automatically adapts to your modifications, then continuously self-tunes in real time to optimum damping at both peak levels and across a broad, changing frequency range. Features precision machined and computer balanced components. Never needs to be tuned or rebuilt. SFI Approved. Made 100% in the U.S.A. ISO Certified.
