This engine isn’t just a fix for a tired powerplant, it’s a purpose-built solution for diesel owners who rely on their trucks day in and day out. Whether you’re hauling trailers, heading to job sites, or simply want the peace of mind that comes from a high-quality remanufactured engine, this long block checks every box. It’s built using only new or OEM-equivalent components, so you’re not getting recycled internals or patchwork repairs. DFC includes top-tier upgrades like ARP or OptiTorque head studs and Cometic MLS head gaskets to fix the common issues these engines face over time. Even better, every unit is backed by a solid 5-year, 100,000-mile warranty, real confidence you can count on. For those who want reliability and performance from a name they can trust, this long block delivers both in one package.\u003c\/p\u003e\n\u003ch4\u003eBuilt With The Right Parts In All The Right Places\u003c\/h4\u003e\n\u003cp\u003eThis Street Series Auto Long Block is engineered with a precise blend of high-quality components and advanced machining techniques to ensure long-term durability. Every block is professionally bored and machined using Rottler CNC equipment, providing exact tolerances for oversized pistons. Those pistons are matched with Total Seal gapless rings that improve compression and reduce blow-by under load. A fully remanufactured cylinder head comes standard and is built with new valves, seats, guides, and stem seals to eliminate the weak links in older engines. The rockers and pushrods are pre-set to factory specifications, which takes the guesswork out of installation and keeps the process smooth for the installer. Unlike basic rebuilds, this long block improves sealing in known problem areas, helping prevent oil leaks and head gasket failures down the road. Designed specifically for automatic transmission setups, it delivers reliable, everyday performance without sacrificing the toughness Cummins owners expect.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fits: \u003c\/strong\u003e 2004.5, 2005, 2006, 2007 Dodge RAM 5.9L Cummins\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThis is a long block, not a complete engine.\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for automatic transmission setups.\u003c\/li\u003e\n\u003cli\u003eCustomer must transfer external components like turbo and injectors.\u003c\/li\u003e\n\u003cli\u003eEngine is remanufactured using all new or OEM-equivalent parts.\u003c\/li\u003e\n\u003cli\u003eBlock is machined to accept next oversized pistons.\u003c\/li\u003e\n\u003cli\u003eCylinder head is fully remanufactured and pressure tested.\u003c\/li\u003e\n\u003cli\u003eAll machining performed using Rottler CNC equipment.\u003c\/li\u003e\n\u003cli\u003eIncludes a full top-end gasket kit for installation.\u003c\/li\u003e\n\u003cli\u003eCore return required and must meet acceptance criteria.\u003c\/li\u003e\n\u003cli\u003eStreet Series is optimized for daily driving and light-duty use.\u003c\/li\u003e\n\u003cli\u003eWarranty coverage is 5 years or 160,000 km (100,000 miles).\u003c\/li\u003e\n\u003cli\u003eInstallation by a professional technician is strongly recommended.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-end=\"931\" data-start=\"884\"\u003eStreet Series vs Tow\/Haul vs Tow\/Haul HD\u003c\/h3\u003e\n\u003cul data-end=\"1398\" data-start=\"933\"\u003e\n\u003cli data-end=\"1099\" data-start=\"933\"\u003e\n\u003cp data-end=\"1099\" data-start=\"935\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong data-end=\"952\" data-start=\"935\"\u003eStreet Series\u003c\/strong\u003e:\u003c\/span\u003e\u003cstrong\u003e Ideal for daily driving, light work, and diesel enthusiasts.
