By installing a Fluidampr viscous damper (crank pulley) you will reduce wear on the main bearings and timing gear, achieve more accurate valvetrain operation and lower the risk of crank failure. \u003cbr\u003e\u003cbr\u003eUnlike 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. \u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Fluidampr","offers":[{"title":"Default Title","offer_id":48062458462426,"sku":"FDR531101","price":482.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/8623\/0234\/files\/a4e773ec10813059a21b951c2256aaac__28555.1694703749.1280.1280.jpg?v=1781530169","url":"https:\/\/www.iagperformance.com\/products\/fluidampr-subaru-ej-series-steel-internally-balanced-damper-531101","provider":"IAG Performance","version":"1.0","type":"link"}
