Subaru

Normal stock dampers wear out and engine performance upgrades increase naturally occurring harmful crankshaft torsional vibrations. Install a Fluidampr viscous damper to 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 any engine modifications and constantly self-tunes in real time to protect across the entire RPM range. Features precision machined and computer balanced components that never need to be tuned or rebuilt.
