Fluidampr Viscous Harmonic Damper – Subaru WRX / STI EJ20 / EJ25

Fluidampr Viscous Harmonic Damper – Subaru WRX / STI EJ20 / EJ25

Application: Subaru WRX / WRX STI – EJ20 / EJ25
Part Type: Viscous harmonic damper
Part Number: 531101

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. As the engine revs up, torsional vibration suspends the inertia ring and reduces its weight felt on the crankshaft — measured as rotating weight, this effect helps maintain quick revs while preserving optimum dampening.

A must-have for instant protection against turbo and NOS power surges.
