Where the stock elastomer damper is tuned to one frequency and ages out, this unit's free-rotating inertia ring in viscous silicone controls torsional vibration across the whole RPM range and adapts as the engine is modified, reducing wear on main bearings and lowering crankshaft-failure risk. Precision-machined, computer-balanced steel with a black zinc finish and engraved timing marks; SFI 18.1 rated, internally balanced, 9-1\/4-inch OD. It never needs rebuilding or tuning, and its tapered housing lets you change the serpentine belt without removing the damper. Drill pin kit 300002 is recommended over 3,500 RPM.\u003c\/p\u003e\u003cp\u003eBrand: Fluidampr\u003c\/p\u003e","brand":"Fluidampr","offers":[{"title":"Default Title","offer_id":67710989500565,"sku":"FD920321","price":643.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0804\/5995\/6373\/files\/FD920321.jpg?v=1792200376","url":"https:\/\/turn4diesel.com\/products\/fluidampr-920321-performance-diesel-series-damper-dodge-ram-2500-3500-6-7l-cummins-2007-5-2018","provider":"Turn4Diesel","version":"1.0","type":"link"}
