{"title":"Fluidampr","description":"\u003cp\u003eFluidampr engineers premium viscous harmonic dampers built to control destructive crankshaft torsional vibration across the entire RPM range. Unlike traditional elastomer-style balancers that target a narrow frequency band and degrade over time, Fluidampr uses a sealed steel housing filled with silicone fluid and a precision-tuned inertia ring to deliver broad-range damping that protects your engine's bottom end, timing components, and accessory drive from premature wear. At Stateside Performance, we stock Fluidampr steel externally balanced harmonic dampers designed specifically for hard-working diesel platforms like the 6.6L Duramax, giving Chevy Silverado 2500HD, Silverado 3500HD, GMC Sierra 2500HD, and Sierra 3500HD owners a proven upgrade for towing, hauling, and performance tuning applications. Whether you're running stock power or you've added turbo upgrades, injectors, and aggressive tuning, a Fluidampr damper helps reduce harmonic stress that can lead to cracked crankshafts, broken keyways, and worn main bearings. Beyond the Duramax lineup, Fluidampr also offers fitments for other popular truck and SUV platforms from Ford, Chevy, GMC, Ram, Dodge, Jeep, and Cadillac, making them a go-to choice for enthusiasts who demand serious protection under serious load. Each damper is SFI 18.1 certified for competition use, corrosion-resistant, and backed by decades of engineering refinement trusted by diesel builders, drag racers, and daily-driven fleet owners alike. If you're serious about protecting your investment and extending the life of your engine, upgrading to a Fluidampr is one of the smartest additions you can make. Browse our full Fluidampr lineup below to find the right harmonic damper for your truck.\u003c\/p\u003e","products":[{"product_id":"fluidampr-2020-gm-6-6l-duramax-steel-externally-balanced-damper","title":"Fluidampr Steel Externally Balanced Harmonic Damper - 6.6L Duramax | 2020-2026 Chevy Silverado 2500HD","description":"\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@type\":\"Product\",\"name\":\"Fluidampr Steel Externally Balanced Harmonic Damper - 6.6L Duramax | 2020-2026 Chevy Silverado 2500HD\",\"description\":\"Fits 2020-2026 Chevy Silverado 2500HD.
