The DFC Diesel KORE5904507STSOALB is designed for 2004.5-2007 Ram 2500 and 3500 trucks with the standard 325 horsepower 5.9L Cummins configuration, combining a professionally prepared long block with Speed of Air piston technology. By improving combustion efficiency, Speed of Air reports fuel economy gains of 15% to 25% or more while also delivering increased torque, horsepower, and pulling power. That extra efficiency can be especially valuable in a truck that spends its days towing equipment, covering long highway distances, or carrying the loads that make a diesel earn its keep. Lower EGTs of 100 to 200 degrees have also been reported during testing, while reduced soot can contribute to cleaner operation and fewer service demands over time. DFC rounds out the package with quality components including Mahle pistons and bearings, Total Seal gapless rings, a cylinder head, preset rockers and pushrods, and the gaskets needed to complete installation. For an owner who already knows the value of keeping a 5.9L Cummins on the road, this long block provides a way to rebuild around proven hardware while adding technology designed to make each combustion event more productive.\u003c\/p\u003e\n\u003ch4\u003ePiston Surface Engineering Changes How Combustion Behaves\u003c\/h4\u003e\n\u003cp\u003eThe key difference inside this KORE Series engine is found on the Speed of Air Hyperformance pistons, where precisely CNC machined indentations called turbulators alter the conditions surrounding the combustion flame front. These patented features create a thinner and well attached boundary layer between the air and fuel mixture and the combustion chamber surfaces, allowing combustion to occur closer to the cooler metal walls. More complete use of the mixture helps increase overall combustion efficiency, which supports the documented improvements in fuel consumption, power delivery, emissions, and drivability. Speed of Air also applies an aerospace proven thermal barrier coating to the piston crowns, helping retain heat within the combustion process so more energy can contribute to useful power. An anti friction coating on the piston skirts reduces abrasion and resistance as each piston travels through its bore, adding another efficiency focused element to the design. The specialized piston technology is produced to exact tolerances under ISO 9001 quality standards, while the custom piston kits are manufactured by licensed producer United Engine and Machine Co. Combined with new Mahle bearings, Total Seal gapless rings, fresh sealing components, and the included cylinder head assembly, this technology gives the 2004.5-2007 5.9L Cummins a carefully engineered foundation for its next round of service.\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 the standard 325 horsepower engine.\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 complete short block and cylinder head.\u003c\/li\u003e\n\u003cli\u003eRockers and pushrods are preset to factory specs.\u003c\/li\u003e\n\u003cli\u003eComplete top end gasket kit is included.\u003c\/li\u003e\n\u003cli\u003eManufacturer performance results are based on testing.\u003c\/li\u003e\n\u003cli\u003eActual fuel economy improvements may vary.\u003c\/li\u003e\n\u003cli\u003eLower EGT and emissions results may vary.\u003c\/li\u003e\n\u003cli\u003eListed shipping weight is 828 pounds.\u003c\/li\u003e\n\u003cli\u003eCalifornia Proposition 65 warning applies.\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":54419301433628,"sku":"DDUKORE5904507STSOALB","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-kore5904507stsoalb-kore-series-standard-speed-of-air-long-block-325hp-2004-5-2007-dodge-ram-2500-3500-5-9l-cummins","provider":"Alligator Performance","version":"1.0","type":"link"}
