The Fluidampr 830121 Harmonic Balancer is designed to control those destructive torsional vibrations before they can take a toll on critical engine components. That means added protection for your crankshaft and bearings while giving your engine the opportunity to deliver smoother, more consistent power. Additionally, many performance enthusiasts choose Fluidampr because it has been shown to support increased torque and horsepower by reducing unwanted crankshaft harmonics. This makes it an excellent upgrade for trucks running tuners, programmers, or other performance modifications that place additional stress on the rotating assembly. Unlike conventional elastomer dampers that can lose effectiveness over time, Fluidampr uses proven viscous damping technology that continues to perform across a broad RPM range. It is an investment that helps protect your engine while allowing you to enjoy every bit of your Duramax's performance. \u003c\/p\u003e \n\n\u003ch4\u003e Advanced Viscous Technology Built For Serious Diesel Performance \u003c\/h4\u003e \n\n\u003cp\u003e Designed specifically for 2011-2016 GM 6.6L Duramax applications, the Fluidampr 830121 Harmonic Balancer combines precision engineering with long lasting durability. Its internal design features a free rotating inertia ring housed inside a laser sealed steel body, with a precisely measured layer of viscous silicone between the components. Furthermore, both the inertia ring and outer housing are computer balanced to meet or exceed OEM specifications, helping maintain smooth operation throughout the engine's operating range. As torsional vibrations travel through the crankshaft, the inertia ring reacts independently and converts that harmful energy into heat, which is then dissipated through the housing. This design provides effective vibration control across a wide frequency range instead of targeting only a narrow operating window like many factory elastomer dampers. Finished with a corrosion resistant black zinc coating and built from durable steel, this harmonic balancer is engineered to provide dependable performance in demanding diesel applications. The result is a premium component that delivers reliable engine protection while supporting the long term durability of your Duramax. \u003c\/p\u003e \n\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2011, 2012, 2013, 2014, 2015, 2016 GM\/Chevy Silverado 2500HD\/3500HD 6.6L Duramax \u003c\/p\u003e \n\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e \u003c\/p\u003e\u003cul\u003e\n  \u003cli\u003eDesigned for 2011-2016 GM 6.6L Duramax applications.\u003c\/li\u003e\n  \u003cli\u003eManufactured to meet or exceed OEM specifications.\u003c\/li\u003e\n  \u003cli\u003eRecommended for high performance diesel engines with tuners or programmers.\u003c\/li\u003e\n  \u003cli\u003eHelps protect against destructive torsional crankshaft vibrations.\u003c\/li\u003e\n  \u003cli\u003eUses viscous silicone damping instead of stock elastomer material.\u003c\/li\u003e\n  \u003cli\u003eDesigned to protect across a broad frequency range.\u003c\/li\u003e\n  \u003cli\u003eComputer balanced during manufacturing for precise operation.\u003c\/li\u003e\n  \u003cli\u003eFeatures an external balance design for this application.\u003c\/li\u003e\n  \u003cli\u003eConstructed from steel with a black zinc finish.\u003c\/li\u003e\n  \u003cli\u003eWeighs approximately 24 lbs with an 8-3\/8 inch outside diameter.\u003c\/li\u003e\n\u003c\/ul\u003e  ","brand":"Fluidampr","offers":[{"title":"Default Title","offer_id":54262494757148,"sku":"FLU830121","price":574.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/fluidampr-830121.jpg?v=1782923108","url":"https:\/\/www.alligatorperformance.com\/products\/fluidampr-830121-harmonic-balancers-2011-2016-gm-chevy-silverado-2500hd-3500hd-6-6l-duramax","provider":"Alligator Performance","version":"1.0","type":"link"}
