Fluidampr Subaru EJ Series Steel Internally Balanced Performance Damper 1995-2021 (SFI 18.1)

Fits select 1995-2021 Subaru Impreza, WRX, STI, Legacy, Outback, Forester, Baja, and 2005 Saab 9-2X models equipped with the EJ-series engine.

Protect your engine's bottom end with the Fluidampr performance viscous damper. Unlike factory elastomeric balancers that use a rubber ring tuned to a specific frequency, the Fluidampr features a precision-machined housing filled with specialized silicone. This viscous design controls harmful torsional vibration across the entire RPM range, regardless of modifications or power levels. By neutralizing crankshaft twist, you reduce the risk of catastrophic failure and premature wear on main bearings and timing components.

Each damper is CNC machined from high-grade steel and finished in a corrosion-resistant black zinc. The unit is internally balanced and requires no maintenance or tuning. Whether you are building a high-boost track car or a reliable daily driver, Fluidampr provides the durability required for performance EJ builds.
