Enhance the performance and durability of your Subaru EJ series engine with the Fluidampr Performance Damper (Part #531101). Normal stock dampers can wear out over time, and engine performance upgrades often increase harmful crankshaft torsional vibrations. Installing a Fluidampr viscous damper helps reduce wear on the main bearings and timing gear, improve valvetrain accuracy, and lower the risk of crankshaft failure.

Unlike rubber-based dampers, Fluidampr’s design automatically adapts to any engine modifications and self-tunes in real time across the entire RPM range for consistent protection. Precision machined and computer balanced, this damper requires no tuning or rebuilding—ensuring long-lasting, reliable performance.
