The DFC Diesel 661116LMLLB Long Block Crate Engine is designed specifically for 2011-2016 GM Sierra and Silverado trucks equipped with the 6.6L Duramax LML, giving you a dependable replacement that feels right at home under the hood. Every engine is remanufactured to factory specifications using new OEM or equivalent components, which means you are not just getting repaired parts but a carefully rebuilt engine designed for long term durability. The block is professionally machined and bored for the next oversized piston, ensuring proper tolerances and consistent performance. What's more, the engine arrives with the rockers and pushrods preset to factory specs and includes a complete top end gasket kit to help simplify installation. That attention to detail saves time in the garage and helps ensure everything goes together smoothly. To top it off, DFC backs this engine with an impressive 5 year 160,000 km warranty, giving you the confidence to put your truck back to work without second guessing the reliability under the hood.\u003c\/p\u003e\n\u003ch4\u003ePrecision Machining And OEM Spec Rebuild For Reliable LML Performance\u003c\/h4\u003e\n\u003cp\u003eUnder the surface, this long block is built with the kind of precision that serious diesel owners appreciate. Each engine begins with a thoroughly inspected Duramax block that is CNC machined using advanced Rottler equipment, an industry standard for high accuracy engine rebuilding. The machining process restores critical tolerances and prepares the block for oversized pistons, allowing for a tight and consistent internal fit. Inside the engine you will find all new pistons, rings, and gaskets that meet or exceed OEM specifications, ensuring proper sealing, compression, and long term durability. The remanufactured cylinder heads are also completely refreshed with new valve seats, guides, valves, and stem seals, then resurfaced and magnafluxed to verify structural integrity. This careful process ensures the heads are ready to handle the heat and pressure that comes with Duramax diesel performance. Additionally, the long block includes the complete short block assembly and cylinder heads already installed, giving installers a solid foundation to finish the build with confidence. The result is a professionally rebuilt 6.6L Duramax LML engine that delivers factory level reliability with the precision expected from a high quality remanufactured powerplant.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e2011, 2012, 2013, 2014, 2015, 2016 GM Sierra\/Silverado 6.6L Duramax LML\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eConfirm fitment for 2011-2016 LML trucks\u003c\/li\u003e\n\u003cli\u003eAlso fits 2011-2016 GM \u003cspan\u003e6.6L Duramax LGH trucks\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eLong block only not complete engine\u003c\/li\u003e\n\u003cli\u003eIncludes short block heads and gaskets\u003c\/li\u003e\n\u003cli\u003eTop end gasket kit included for install\u003c\/li\u003e\n\u003cli\u003eRockers and pushrods preset to spec\u003c\/li\u003e\n\u003cli\u003eBlock bored for next oversized piston\u003c\/li\u003e\n\u003cli\u003eBuilt with new name brand components\u003c\/li\u003e\n\u003cli\u003eCylinder heads magnafluxed and resurfaced\u003c\/li\u003e\n\u003cli\u003eRottler CNC machining used throughout\u003c\/li\u003e\n\u003cli\u003eWarranty is 5 years 160000 km\u003c\/li\u003e\n\u003cli\u003eReview warranty terms before purchase\u003c\/li\u003e\n\u003cli\u003eCalifornia Prop 65 warning applies\u003c\/li\u003e\n\u003cli\u003eShipping charge of $500\u003c\/li\u003e\n\u003cli\u003eCore Charge of $2400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFC Diesel","offers":[{"title":"Default Title","offer_id":68060701720849,"sku":"DDU-661116LMLLB","price":9697.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0477\/1089\/files\/image_2__62373.jpg?v=1794721624","url":"https:\/\/gautoparts.com\/products\/dfc-diesel-661116lmllb-long-block-crate-engine-2011-2016-gm-sierra-silverado-6-6l-duramax-lml","provider":"Guaranteed Auto Parts","version":"1.0","type":"link"}
