The DFC Diesel KORE Series Short Block gives 2003-2006 Super Duty owners a third option built specifically for value without cutting corners on the parts that matter. Every KORE Series short 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. Fresh front and rear main seals help keep the rebuild leak free from day one, and DFC machines every component to OEM specifications or better, so you're not sacrificing precision just because you're choosing the more affordable series. The block is built with 18mm head dowels, so pairing it correctly with your cylinder head and gasket setup is straightforward for anyone familiar with this platform. Whether you're running a daily driver that needs to stay dependable or a commercial truck that can't afford downtime, this short block gives you real Mahle components without paying new-engine pricing. For a 6.0L owner who wants a trustworthy rebuild done right, 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 KORE600306STAUSOA18SB is a remanufactured short block engineered specifically for 2003-2006 Ford F250 and F350 Super Duty trucks equipped with the 6.0L Powerstroke engine, compatible with both standard and automatic transmission applications. The short block 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 front and rear main seals are installed to help ensure a proper seal at both ends of the engine, and a complete gasket set is included to support installation. Every component is professionally machined to meet or exceed OEM specifications, and the block is built with 18mm head dowels, an important detail to confirm against your cylinder head and gasket setup before installation. As a short block, the cylinder head is not included and must be sourced or reused separately. 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 2003, 2004, 2005, 2006 Ford F250\/F350 Super Duty 6.0L Powerstroke18mm head dowels\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThis is a short block only, cylinder head not included\u003c\/li\u003e\n\u003cli\u003eBuilt with 18mm head dowels\u003c\/li\u003e\n\u003cli\u003e$500 shipping charge\/$2,800 core charge \u003c\/li\u003e\n\u003cli\u003eConfirm head and gasket compatibility before ordering\u003c\/li\u003e\n\u003cli\u003eWarranty is parts-only, 1 year unlimited mileage, for both standard\/commercial use\u003c\/li\u003e\n\u003cli\u003e[VERIFY: oil pan inclusion, core charge amount, and California shipping restriction for this specific SKU]\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":54607049294108,"sku":"DDUKORE600306STAUSOA18SB","price":7151.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/DFC_03-07_6-0_Short-Block_web_600x600_1_1b5a00d0-0748-4cf0-89d4-6e039359417a.webp?v=1790353785","url":"https:\/\/www.alligatorperformance.com\/products\/dfc-diesel-kore600306stausoa18sb-kore-series-speed-of-air-short-block-std-auto-2003-2006-ford-f250-f350-super-duty-6-0l-powerstroke-18mm-dowels","provider":"Alligator Performance","version":"1.0","type":"link"}
