The DFC Diesel 600306STAUSOA18SB Speed of Air Short Block gives 2003-2006 Ford F250 and F350 owners an upgraded foundation built around technology designed to improve the combustion process. Speed of Air reports fuel economy improvements reaching 15% to 25% or more in testing, along with EGT reductions of 100 to 200 degrees and smoother engine operation. Better combustion can also improve torque, horsepower, drivability, and pulling power, which matters when your Super Duty spends its time hauling equipment, towing a trailer, or handling everyday work. Reduced soot production is another valuable benefit because cleaner operation can help limit contamination and contribute to longer engine life with fewer service demands. The short block includes the oil pan, internal components, a complete installation gasket kit, and important instructions to help support the installation process. For owners already committed to rebuilding their Powerstroke, this assembly offers a practical way to combine fresh engine hardware with combustion technology developed to deliver meaningful benefits after the truck is back on the road.\u003c\/p\u003e\n\u003ch4\u003eAdvanced Piston Design Puts Combustion To Better Use\u003c\/h4\u003e\n\u003cp\u003eThe defining technology inside this DFC Diesel short block comes from Speed of Air Hyperformance pistons, which use patented CNC machined indentations called turbulators across the piston tops. Rather than acting as a cosmetic piston modification, these precisely engineered features influence the boundary layer between the air and fuel mixture, the flame front, and the combustion chamber walls. Creating a thinner and more turbulent boundary layer allows the flame front to burn closer to the cooler chamber surfaces, helping improve overall combustion efficiency. Each piston crown also uses an aerospace proven thermal barrier coating that retains more heat within the combustion event, helping turn that energy into useful efficiency and power. The piston skirts receive an anti friction coating to minimize abrasion and resistance as the pistons move through the cylinders, supporting both efficiency and smooth operation. Speed of Air specifies that this 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. With specialized piston geometry and purpose selected coatings working together inside the assembly, this short block takes a more engineered approach to rebuilding the 2003-2006 6.0L Powerstroke.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 2003, 2004, 2005, 2006 Ford F250\/F350 6.0L Powerstroke\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for 2003-2006 Ford 6.0L Powerstroke applications.\u003c\/li\u003e\n\u003cli\u003eIntended for standard and automatic transmission configurations.\u003c\/li\u003e\n\u003cli\u003eThis is a short block assembly, not a complete engine.\u003c\/li\u003e\n\u003cli\u003eManufacturer notes indicate front cover is not included.\u003c\/li\u003e\n\u003cli\u003eManufacturer notes indicate rear cover is not included.\u003c\/li\u003e\n\u003cli\u003eIncludes oil pan and internal engine components.\u003c\/li\u003e\n\u003cli\u003eComplete installation gasket kit is included.\u003c\/li\u003e\n\u003cli\u003eImportant installation instructions are supplied.\u003c\/li\u003e\n\u003cli\u003eReported performance gains are based on manufacturer testing.\u003c\/li\u003e\n\u003cli\u003eActual fuel economy and emissions results may vary.\u003c\/li\u003e\n\u003cli\u003eProfessional installation is recommended for proper setup.\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":54418864832796,"sku":"DDU600306STAUSOA18SB","price":8854.36,"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_72570a52-aaa6-4c91-b28e-cf8669f34be8.webp?v=1786381683","url":"https:\/\/www.alligatorperformance.com\/products\/dfc-diesel-600306stausoa18sb-speed-of-air-short-block-std-auto-2003-2006-ford-f250-f350-6-0l-powerstroke","provider":"Alligator Performance","version":"1.0","type":"link"}
