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.

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 DFC Diesel 661116LMLSOASBCC Speed of Air Short Block gives 2011-2016 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD owners a new engine foundation featuring a premium Callies crankshaft. That crankshaft makes this configuration especially appealing when you want quality hardware at the heart of the rotating assembly instead of taking chances with one of the most critical components in the engine. Speed of Air technology adds another performance minded element to the package, making this short block a compelling choice for an LML that sees towing, hauling, highway miles, or regular work duty. DFC also includes the internal components, oil pan, front cover with seal, and rear cover with main seal, so you are starting the project with more of the essential pieces already in place. A complete installation gasket kit and important instructions are supplied to help your installer move through the remaining assembly with the correct supporting materials on hand. When the goal is to put your Duramax back to work with a well equipped foundation underneath it, this Callies crankshaft configuration gives the rebuild a strong place to start.\u003c\/p\u003e\n\u003ch4\u003eA Premium Crankshaft Anchors The Rotating Assembly\u003c\/h4\u003e\n\u003cp\u003eThe DFC Diesel 661116LMLSOASBCC is configured as a Speed of Air short block for standard automatic 2011-2016 GM trucks equipped with the 6.6L Duramax LML. Its Callies crankshaft sits at the center of the rotating assembly, where it converts piston movement into the rotational force ultimately delivered through the drivetrain. Because the crankshaft carries significant combustion and rotational loads during operation, the inclusion of a premium Callies unit is an important distinction between this assembly and the standard version of the short block. All internal short block components are included, providing the core lower engine assembly needed before the remaining LML components and systems are installed. The front cover arrives with its seal and the rear cover includes the main seal, while an oil pan is also supplied as part of the package. Additionally, DFC provides a complete gasket kit for installation along with important instructions that should be reviewed before the engine is assembled and placed into service.

DFC keeps the cost down by leaving out parts you can reuse or buy easily, like the covers, oil pan, and rocker arms, but it does not cut corners on the rebuild itself. Every block is machined and bored on Rottler CNC equipment for use with the next oversized piston, and the tolerances come in better than OEM specs. Inside, you get all new pistons, rings, bearings, gaskets, seals, valves, springs, hardened seats, and cast guides, plus Total Seal gapless piston rings as standard. DFC also builds in improved gasket sealing in the areas where these engines commonly leak. The engine arrives as a short block with the cylinder heads on and a complete top end gasket kit, so the heavy lifting of the rebuild is already done. If you want your LML back on the road without paying for a full premium build, this long block is a solid way to do it.\u003c\/p\u003e\n\u003ch4\u003eRottler Machined Tolerances With Fresh Internals And Heads Already On\u003c\/h4\u003e\n\u003cp\u003eThe DFC Diesel KORE661116LMLLB is a remanufactured long block engineered for 2011-2016 GM Silverado and Sierra 2500HD and 3500HD trucks with the 6.6L Duramax LML, listed for standard and automatic transmission applications. The block is professionally machined and bored on Rottler CNC equipment for use with the next oversized piston, with tolerances better than OEM specifications. The engine includes all new pistons, rings, bearings, gaskets, seals, valves, springs, hardened seats, stem seals, and cast guides, and it comes standard with Total Seal gapless piston rings and improved gasket sealing in common leak areas. It ships as a complete short block assembly with the cylinder heads installed, along with a complete top end gasket kit to finish the install. It does not include the front cover, rear cover, oil pump, upper or lower oil pan, oil pickup tube, rocker arms, pushrods, or valve bridges. Bolt-on parts such as the valve covers, intake, exhaust, fuel system, and turbo must be swapped over from your existing engine, and the customer is responsible for having the injectors, injection pumps, and fuel system professionally tested, cleaned, and replaced if needed. To keep the warranty valid, a new oil cooler, new air, oil, and fuel filters, a new water pump, and new lubricating oil are required at installation.

This DFC Diesel KORE Series long block answers that worry by building the engine around an upgraded Callies Compstar-Durastar crankshaft instead of a stock one. The crank is made from hardened 4340 steel with a deep DuraCase nitride treatment, and that treatment is there to improve durability and wear over the long haul. Every journal has True Form fillet radii, the timing gear is keyed so it resists shearing, and the rod journals are drilled to cut down on inertia and make balancing easier. Because it keeps the OEM stroke, journal diameters, and flywheel fit, it goes in without a pile of specialty parts. Around that crank you still get everything the KORE Series is known for, including Rottler machined tolerances better than OEM, all new pistons, rings, bearings, and valves, and Total Seal gapless rings as standard. DFC keeps the price in check by leaving out parts you can reuse, so you get a stronger bottom end without paying for a full premium build. For a 2011-2016 Silverado or Sierra HD that you plan to work hard, this is a smart place to put your money.\u003c\/p\u003e\n\u003ch4\u003eHardened 4340 Steel Crank Inside A Rottler Machined Long Block\u003c\/h4\u003e\n\u003cp\u003eThe DFC Diesel KORE661116LMLLBCC 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 an upgraded Callies Compstar-Durastar crankshaft in place of the factory unit. The crank is made from hardened 4340 steel with a deep DuraCase nitride treatment, drilled rod journals, and True Form fillet radii on every journal, polished to a 6Ra or finer finish. It keeps the OEM stroke of 3.898 inches along with OEM journal diameters and width, uses a dual keyed damper fit, and has a keyed timing gear to prevent shearing. It accepts OEM post and flange bolts as well as OEM flywheels and flexplates, and the main bearing oil holes have lead-ins to improve cold start oil flow to the rod journals.

It uses Speed of Air Hyperformance pistons, which DFC developed together with Speed of Air for medium duty diesel applications. The piston tops have precise, CNC machined indentations called turbulators, which are often described simply as dimples. According to DFC and Speed of Air, those dimples help the flame front burn closer to the cool metal walls of the combustion chamber, which improves combustion efficiency. DFC says that can mean increased fuel mileage, better drivability and power, and lower operating costs, though results will vary by truck and how you drive it. The pistons also carry an aerospace proven thermal barrier coating on the crowns and an anti friction coating on the skirts, so more heat stays in the combustion process while friction is reduced. Around those pistons you still get the KORE Series build, with Rottler machined tolerances better than OEM, all new bearings and valves, and Total Seal gapless rings as standard. For a 2011-2016 Silverado or Sierra HD owner who wants more than a like for like replacement, this long block gives your LML a smarter set of pistons at KORE Series pricing.\u003c\/p\u003e\n\u003ch4\u003eTurbulators And Coatings Engineered Into Every Piston Crown\u003c\/h4\u003e\n\u003cp\u003eThe DFC Diesel KORE661116LMLSOALB 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. The Speed of Air Hyperformance pistons use patented turbulator indentations that are CNC machined into the piston top and made to exacting tolerances under ISO 9001 quality standards. These create a thinner, well attached boundary layer between the air fuel mixture, its flame front, and the combustion chamber walls. Speed of Air says this lets the flame burn closer to the cool metal walls, which raises combustion efficiency and supports lower fuel consumption, more torque and horsepower, and better pulling power. The pistons are also coated, with a thermal barrier on the crowns and an anti friction coating on the skirts. 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.

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.
