Streetdampr (Non-SFI) by Fluidampr Great value for non-SFI required applications. Same Fluidampr quality and protection. Normal stock damper wear and engine performance upgrades increase the naturally occurring characteristics of harmful crankshaft torsional vibrations. By installing a Streetdampr by 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, Streetdampr 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. Made 100% in the U.S.A. ISO Certified.
