Enhance the performance and reliability of your 1990–2001 Honda B-Series engine with the Fluidampr Performance Damper (Part #590601). Stock rubber dampers degrade over time, allowing harmful crankshaft torsional vibrations to increase—especially in high-performance or modified engines. The Fluidampr viscous damper controls these vibrations to protect internal components, improve valvetrain accuracy, and reduce the risk of crankshaft failure.

Unlike traditional rubber-based dampers, Fluidampr automatically adapts to engine modifications and self-tunes in real time across the entire RPM range. Each damper is precision CNC-machined, computer balanced, and constructed from high-grade steel with a hard coat anodized pulley for long-lasting performance. No tuning, rebuilding, or maintenance required.

Note: If the pulley is removed, torque the (9) 1/4-20 x 3/4" bolts to 120 in-lbs (10 ft-lbs) during reassembly.
