Designed for LLY, LBZ, and LMM applications, this viscous crankshaft damper provides broad-range vibration control for stock, work, towing, performance, and competition-built trucks.\u003c\/p\u003e\n\n\u003cp\u003eFluidampr uses viscous damping technology to automatically respond to changing torsional vibration frequencies throughout the engine's operating range. This allows the damper to accommodate changes in engine speed and configuration without requiring rebuilding or retuning, helping reduce stress and wear on the crankshaft, main bearings, valvetrain, and other critical engine components.\u003c\/p\u003e\n\n\u003cp\u003ePrecision CNC-machined and computer-balanced steel components provide accurate operation, while engraved markings and a corrosion-resistant black zinc finish provide durability and serviceability. The updated design also allows serpentine belt replacement without removing the damper. Manufactured in the USA, the Fluidampr 830111 is built to SFI 18.1 specifications for competition use.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePerformance Diesel Series viscous crankshaft damper\u003c\/li\u003e\n  \u003cli\u003eDesigned for 2006–2010 GM 6.6L Duramax applications\u003c\/li\u003e\n  \u003cli\u003eReduces harmful crankshaft torsional vibration across a broad RPM range\u003c\/li\u003e\n  \u003cli\u003eAutomatically adapts to changing vibration frequencies and engine configurations\u003c\/li\u003e\n  \u003cli\u003eHelps reduce stress on the crankshaft, main bearings, and other engine components\u003c\/li\u003e\n  \u003cli\u003eSupports more consistent valvetrain operation\u003c\/li\u003e\n  \u003cli\u003eDesigned to reduce the risk of vibration-related crankshaft damage\u003c\/li\u003e\n  \u003cli\u003ePrecision CNC-machined components\u003c\/li\u003e\n  \u003cli\u003eComputer balanced for accurate operation\u003c\/li\u003e\n  \u003cli\u003eSteel construction\u003c\/li\u003e\n  \u003cli\u003eEngraved markings\u003c\/li\u003e\n  \u003cli\u003eBlack zinc corrosion-resistant finish\u003c\/li\u003e\n  \u003cli\u003eNever requires rebuilding or tuning\u003c\/li\u003e\n  \u003cli\u003eDamper removal is not required for serpentine belt replacement\u003c\/li\u003e\n  \u003cli\u003eSFI 18.1 specification for competition applications\u003c\/li\u003e\n  \u003cli\u003eManufactured in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOutside Diameter: 9-1\/4\"\u003c\/li\u003e\n  \u003cli\u003eLength: 2.665\"\u003c\/li\u003e\n  \u003cli\u003eMaterial: Steel\u003c\/li\u003e\n  \u003cli\u003eWeight: 25.1 lbs.\u003c\/li\u003e\n  \u003cli\u003eFinish: Black Zinc\u003c\/li\u003e\n  \u003cli\u003eBalance: Internal\u003c\/li\u003e\n  \u003cli\u003eSFI Specification: 18.1\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e2006 GM applications equipped with the 6.6L Duramax LLY diesel engine\u003c\/li\u003e\n  \u003cli\u003e2006–2007 GM applications equipped with the 6.6L Duramax LBZ diesel engine\u003c\/li\u003e\n  \u003cli\u003e2007.5–2010 GM applications equipped with the 6.6L Duramax LMM diesel engine\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FluidAMPR","offers":[{"title":"Default Title","offer_id":54015690539291,"sku":"830111","price":574.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0962\/5757\/3147\/files\/Screenshot2026-09-22at12.06.30PM.png?v=1790143320","url":"https:\/\/wwmperformance.com\/products\/fluidampr-performance-diesel-series-damper-830111-2006-2010-6-6l-duramax-lly-lbz-lmm","provider":"WWM Performance","version":"1.0","type":"link"}
