The DFC Diesel KORE Series long block is built for that situation, giving 2017-2023 owners a remanufactured L5P at a price that makes the repair realistic. DFC keeps the cost down by leaving out the parts you can reuse from your old engine or buy easily, but it does not cut corners on the rebuild itself. Every engine is machined on Rottler equipment, which gets the tolerances better than OEM specifications. Inside you get all new pistons, rings, bearings, gaskets, seals, valves, springs, hardened seats, stem seals, and cast guides. Total Seal gapless piston rings come standard, and DFC builds in improved gasket sealing in the areas where these engines are known to leak. The engine arrives as a short block with the cylinder heads already on, so the most demanding part of the rebuild is done before it reaches your shop. For an owner who wants a durable replacement without paying for a full premium build, this long block is a practical answer.\u003c\/p\u003e\n\u003ch4\u003eRottler Machined Short Block With Heads Installed For The Final Buildup\u003c\/h4\u003e\n\u003cp\u003eThe DFC Diesel KORE661723L5PLB is a remanufactured long block built for 2017-2023 GM Silverado and Sierra 2500HD and 3500HD trucks with the 6.6L Duramax L5P, listed for standard and automatic transmission applications. DFC machines these engines on Rottler equipment to tolerances better than OEM specifications. The build includes all new pistons, rings, bearings, gaskets, seals, valves, springs, hardened seats, stem seals, and cast guides. It also comes standard with Total Seal gapless piston rings and improved gasket sealing methods in common leak areas. As a long block, it consists of a complete short block assembly with the cylinder heads, ready for the final buildup. It does not include bolt on components such as the valve covers, intake, exhaust, fuel system, or turbo, so those must be swapped over from your existing engine. It also does not include the front cover, rear cover, oil pump, upper or lower oil pan, oil pickup tube, rocker arms, pushrods, or valve bridges. The engine is built in an ISO 9001:2015 certified facility and carries a 1 year, unlimited mileage manufacturer warranty.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 2017, 2018, 2019, 2020, 2021, 2022, 2023 GM Silverado\/Sierra 2500HD\/3500HD 6.6L Duramax L5P\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLong block with cylinder heads installed, ready for the final buildup\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\u003eEngine shipping crate must be returned with core engine for full core credit\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\/manuals\/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":54665548595484,"sku":"DDUKORE661723L5PLB","price":9000.6,"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_e4d2496c-91e0-4b21-bd6d-d31d6a462452.webp?v=1791305917","url":"https:\/\/www.alligatorperformance.com\/products\/dfc-diesel-kore661723l5plb-kore-series-long-block-std-auto-2017-2023-gm-sierra-silverado-2500hd-3500hd-6-6l-duramax-lml","provider":"Alligator Performance","version":"1.0","type":"link"}
