Chevy - Big Block

Normal stock dampers wear out and engine operation upgrades increase naturally occurring harmful crankshaft torsional vibrations. Install a Fluidampr viscous damper to reduce wear on the primary bearings and timing gear, reach more accurate valvetrain operation and lower the take chances of creepo failure. Unlike rubber based dampers, Fluidampr automatically adapts to any engine modifications and constantly self-tunes in real fourth dimension to protect across the unabridged RPM range. Features precision machined and reckoner balanced components that never need to be tuned or rebuilt.
