The DFC Diesel KORE5904507AUSOALB KORE Series Speed of Air Long Block is built for 2004.5-2007 Ram 2500 and 3500 trucks with the 325 horsepower automatic configuration. What makes this version especially interesting is the addition of Speed of Air technology, giving drivers a performance focused alternative to the standard KORE Series long block. DFC pairs that technology with new Mahle pistons, Mahle main and rod bearings, Total Seal gapless rings, and a remanufactured cylinder head to create a package suited for everything from everyday commuting to regular towing and work duty. You also receive the front and rear covers, oil pan, internal components, and preset rockers and pushrods, so your shop starts with much more than a basic replacement block. The included installation gasket kit further simplifies parts planning, while compatibility with most existing components and upgrades makes it easier to finish the engine around your current truck. With DFC advertising a 5 year or 160000 kilometer warranty, this KORE Series Speed of Air long block gives owners a practical way to combine fresh engine hardware with a more specialized approach to their Cummins rebuild.\u003c\/p\u003e\n\u003ch4\u003ePrecision Machine Work Supports The Entire Build\u003c\/h4\u003e\n\u003cp\u003eUnderneath the Speed of Air designation is a carefully prepared KORE Series engine that relies on precision machining and new internal components to establish a dependable foundation. DFC uses advanced Rottler machining equipment and blueprints its cylinder blocks with a Rottler F69 ATC to tolerances the manufacturer states are tighter than OEM specifications. The lower assembly incorporates new Mahle pistons, Total Seal gapless rings, and new Mahle main and rod bearings, while Speed of Air technology distinguishes this configuration from the conventional KORE Series version. Above the block sits a remanufactured cylinder head equipped with new valves, springs, hardened seats, stem seals, and cast guides to refresh critical areas of the valvetrain. DFC also addresses common leakage areas with improved gasket sealing methods and offers an available MLS head gasket upgrade for customers who want that option included in their build. New front and rear main seals provide fresh sealing at both ends of the engine, while the rockers and pushrods arrive preset to factory specifications. Combined with the supplied covers, oil pan, internal components, and complete installation gasket set, the result is a well prepared 325 horsepower automatic long block for 2004.5-2007 5.9L Cummins applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2004.5, 2005, 2006, 2007 Dodge RAM 2500\/3500 5.9L Cummins\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for 2004.5-2007 5.9L Cummins applications.\u003c\/li\u003e\n\u003cli\u003eConfigured for 325 horsepower automatic applications.\u003c\/li\u003e\n\u003cli\u003eThis is a long block assembly, not a complete engine.\u003c\/li\u003e\n\u003cli\u003eThis SKU includes Speed of Air technology.\u003c\/li\u003e\n\u003cli\u003eIncludes a remanufactured cylinder head.\u003c\/li\u003e\n\u003cli\u003eRockers and pushrods are preset to factory specs.\u003c\/li\u003e\n\u003cli\u003eMost existing components and upgrades remain compatible.\u003c\/li\u003e\n\u003cli\u003eComplete installation gasket set is included.\u003c\/li\u003e\n\u003cli\u003eMLS head gasket upgrade is available.\u003c\/li\u003e\n\u003cli\u003eManufacturer states tighter than OEM block tolerances.\u003c\/li\u003e\n\u003cli\u003eDFC advertises a 5 year 100000 mile warranty.\u003c\/li\u003e\n\u003cli\u003eListed shipping weight is 828 pounds.\u003c\/li\u003e\n\u003cli\u003eCore Charge: $2,900.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFC Diesel","offers":[{"title":"Default Title","offer_id":54419225116956,"sku":"DDUKORE5904507AUSOALB","price":8049.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/59-Front_web_8f0142dc-0ff0-4db6-90a1-c7ac5c446581.jpg?v=1786401153","url":"https:\/\/www.alligatorperformance.com\/products\/dfc-diesel-kore5904507ausoalb-kore-series-auto-speed-of-air-long-block-325hp-2004-5-2007-dodge-ram-2500-3500-5-9l-cummins","provider":"Alligator Performance","version":"1.0","type":"link"}
