The DFC Diesel KORE Series Long Block gives 2004.5-2005 LLY Duramax owners a third option built specifically for value without cutting corners on the parts that matter. Every KORE Series long block goes in with new Mahle pistons and Mahle main and rod bearings, paired with Total Seal gapless piston rings for improved sealing compared to standard ring designs. New valves, seats, and guides round out the top end work, while fresh front and rear main seals help keep the rebuild leak free from day one. DFC machines every component to OEM specifications or better, so you're not sacrificing precision just because you're choosing the more affordable series. This makes the KORE Series a smart call whether you're running a daily driver that needs to stay dependable or a commercial truck that can't afford downtime. For an LLY owner who wants real Mahle components without paying new-engine pricing, this is the practical middle ground.\u003c\/p\u003e\n\u003ch4\u003ePrecision Machining Paired With Genuine Mahle Components\u003c\/h4\u003e\n\u003cp\u003eThe DFC Diesel KORE6604505LLYSOALB is a remanufactured long block engineered specifically for 2004.5-2005 GM Silverado and Sierra 2500HD and 3500HD trucks equipped with the 6.6L Duramax LLY engine, compatible with both standard and automatic transmission applications. The long block assembly includes new Mahle pistons, new Mahle main bearings, and new Mahle rod bearings, paired with Total Seal gapless rings for improved sealing compared to standard ring designs. New valves, seats, and guides are installed during the rebuild, along with new front and rear main seals to help ensure a proper seal at both ends of the engine. A complete gasket set is included for installation, and every component is professionally machined to meet or exceed OEM specifications. The KORE Series is manufactured in an ISO 9001:2015 certified facility, reflecting the same quality management standards used across DFC's broader engine lineup. Unlike DFC's standard engine line, the KORE Series carries a 1 year unlimited mileage parts-only warranty that applies to both personal and commercial use. KORE Series engines are designed for compatibility with most existing parts and upgrades, which helps simplify installation and reduces the need to source additional components during the build.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 2004.5, 2005 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax LLY\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWarranty is parts-only, 1 year unlimited mileage, for both standard and commercial use\u003c\/li\u003e\n\u003cli\u003eCompatible with most existing parts and upgrades for easier installation\u003c\/li\u003e\n\u003cli\u003eComponent brands may vary by build based on parts availability, cannot be specially requested\u003c\/li\u003e\n\u003cli\u003e$500 shipping charge\/$2,800 core charge \u003c\/li\u003e\n\u003cli\u003eEngine shipping crate must be returned with core engine for full core credit\u003c\/li\u003e\n\u003cli\u003eThis product cannot be shipped to California\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.xtremediesel.com\/mm5\/warranty\/DFC_Engines_Owners-Guide.pdf\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003eInstall Instructions\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"DFC Diesel","offers":[{"title":"Default Title","offer_id":54627434758428,"sku":"DDUKORE6604505LLYSOALB","price":9601.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/dfc-diesel-soa-series-long-block-crate-engine-2004.5-2005-gm-6.6l-lly-duramax-6604505llysoalb__01877.1719342291.1280.1280__31813.1765206937.1280.1280__66625_c2763d00-bedb-476b-b15d-307a8d5a518c.webp?v=1790783016","url":"https:\/\/www.alligatorperformance.com\/products\/dfc-diesel-kore6604505llysoalb-kore-series-speed-of-air-long-block-std-auto-2004-5-2005-gm-sierra-silverado-2500hd-3500hd-6-6l-duramax-lly","provider":"Alligator Performance","version":"1.0","type":"link"}
