Fluidampr Harmonic Balancer Crank Pulley for EJ WRX/STi (531101)
Fluidampr harmonic balancer crankshaft pulley for the EJ20/EJ25 Subaru WRX and STi models. This balancer helps to reduce destructive crankshaft torsional vibration lessening the wear on critical internal engine components.
Vehicle Fitment:
EJ20/EJ25
2002-2014 Subaru WRX
2004-2020 Subaru STi
More Info:
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.
