Up top, it uses Speed of Air Hyperformance pistons, which have CNC machined turbulator dimples on the piston tops designed to help the flame front burn closer to the cool chamber walls. DFC and Speed of Air say that improves combustion efficiency, with benefits that include better fuel mileage, more torque and horsepower, and improved drivability and pulling power, though results will vary by truck and how it is driven. Down below, the engine is built around an upgraded Callies Compstar-Durastar crankshaft made from hardened 4340 steel with a deep DuraCase nitride treatment, which is there to improve durability and wear. That matters because a broken crank is one of the failures Duramax owners worry about most. The crank keeps OEM journal diameters and accepts OEM flywheels and flexplates, so it goes in without a pile of specialty parts. Everything else is standard KORE Series quality, with Rottler machined tolerances better than OEM, all new bearings and valves, and Total Seal gapless rings. For a 2011-2016 Silverado or Sierra HD that has to work hard and last, this is the most complete way to rebuild an LML on a KORE Series budget.\u003c\/p\u003e\n\u003ch4\u003ePatented Piston Turbulators Paired With A Nitrided 4340 Crankshaft\u003c\/h4\u003e\n\u003cp\u003eThe DFC Diesel KORE661116LMLSOALBCC is a remanufactured long block built for 2011-2016 GM Silverado and Sierra 2500HD and 3500HD trucks with the 6.6L Duramax LML, listed for standard and automatic transmission applications. It uses Speed of Air Hyperformance pistons, which have patented turbulator indentations CNC machined into the piston top to exacting tolerances under ISO 9001 quality standards. The pistons also carry an aerospace proven thermal barrier coating on the crowns and an anti friction coating on the skirts. Main bearing oil holes have lead ins to improve cold start oil flow to the rod journals. The rest of the engine follows DFC's KORE Series process, machined on Rottler equipment to tolerances better than OEM, with all new rings, bearings, gaskets, seals, valves, springs, hardened seats, and cast guides, plus Total Seal gapless piston rings and improved gasket sealing in common leak areas. It ships as a short block with the cylinder heads installed and a complete top end gasket kit, built in an ISO 9001:2015 certified facility with a 1 year, unlimited mileage manufacturer warranty.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 2011, 2012, 2013, 2014, 2015, 2016 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax LML\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt with Speed of Air Hyperformance pistons and an upgraded Callies Compstar-Durastar crankshaft, not the factory crank\u003c\/li\u003e\n\u003cli\u003eFuel mileage, power, and torque gains are manufacturer claims, results will vary\u003c\/li\u003e\n\u003cli\u003eCrankshaft keeps the OEM stroke and journal diameters and accepts OEM flywheels and flexplates\u003c\/li\u003e\n\u003cli\u003eLong block with cylinder heads installed and a complete top end gasket kit included\u003c\/li\u003e\n\u003cli\u003eNew oil cooler required for warranty coverage, sold separately\u003c\/li\u003e\n\u003cli\u003eNew air, oil, and fuel filters required for warranty coverage, sold separately\u003c\/li\u003e\n\u003cli\u003eNew water pump required for warranty coverage, sold separately\u003c\/li\u003e\n\u003cli\u003eNew lubricating oil required for warranty coverage, sold separately\u003c\/li\u003e\n\u003cli\u003eWarranty is void if not installed with the fluids specified by the manufacturer\u003c\/li\u003e\n\u003cli\u003eDoes not include bolt on components such as valve covers, intake, exhaust, fuel system, or turbo, swap these over from your existing engine\u003c\/li\u003e\n\u003cli\u003eDoes not include front cover, rear cover, oil pump, upper or lower oil pan, oil pickup tube, rocker arms, pushrods, or valve bridges\u003c\/li\u003e\n\u003cli\u003eCustomer is responsible for professionally testing, cleaning, and replacing injectors, injection pumps, and fuel system as needed\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\u003eManufacturer warranty: 1 year, unlimited mileage\u003c\/li\u003e\n\u003cli\u003eTurbocharger replacement recommended over 125K miles, mandatory if shaft play present or engine was dusted\u003c\/li\u003e\n\u003cli\u003eInjector replacement highly recommended on higher mileage or contaminated fuel engines\u003c\/li\u003e\n\u003cli\u003eEvans Waterless Coolant recommended upgrade for corrosion and boilover prevention\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\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eInstall Instructions\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"DFC Diesel","offers":[{"title":"Default Title","offer_id":54665533456668,"sku":"DDUKORE661116LMLSOALBCC","price":13015.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/dfc-diesel-long-block-crate-engine-2011-2016-gm-6.6l-lml-duramax-661116lmllb__77436_ae39e876-a2ef-4fc1-a058-6a1a53901144.webp?v=1791305037","url":"https:\/\/www.alligatorperformance.com\/products\/dfc-diesel-kore661116lmlsoalbcc-kore-series-speed-of-air-callies-crankshaft-long-block-std-auto-2011-2016-gm-sierra-silverado-2500hd-3500hd-6-6l-duramax-lml","provider":"Alligator Performance","version":"1.0","type":"link"}
