Built by DFC Diesel to outperform a factory replacement, this engine is a solid choice for daily drivers, work trucks, and anyone who expects more from their build. It’s not just rebuilt, it’s reengineered using premium name-brand parts that correct the common weak points of the original 5.9L Cummins platform. You get a remanufactured long block that includes everything from a rebuilt cylinder head to a full top-end gasket kit, with rockers and pushrods pre-set to factory spec to make installation smoother. And it’s backed by a 5-year, 100,000-mile warranty, so you know you’re getting something that’s meant to last. Whether you're hauling heavy loads or just need peace of mind on the open road, this engine delivers dependable power and long-term confidence. It’s the kind of investment that pays for itself in reliability and performance.\u003c\/p\u003e\n\u003ch4\u003ePrecision Workmanship That Brings Old Power Back To Life\u003c\/h4\u003e\n\u003cp\u003eDFC’s Street Series Standard Long Block is assembled with a focus on clean tolerances, heat management, and long-term performance. Every unit starts with a professionally machined block using advanced Rottler CNC equipment, then bored to accept oversized pistons for a tighter, more efficient seal. The internals include new pistons, rings, bearings, valves, springs, and gaskets, all meeting or exceeding OEM standards. The cylinder head is completely remanufactured, magnafluxed, resurfaced, and rebuilt with new guides, seats, and stem seals to ensure consistent performance under load. Total Seal gapless piston rings improve compression and reduce blow-by, while improved piston cooling helps protect against failures caused by faulty injectors. Factory-spec pushrods and rockers come preset for easy install, saving you time and guesswork in the shop. Combined with enhanced sealing in areas known for leaks, this long block delivers a stronger, more durable foundation for any manual-transmission Cummins truck.\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 manual transmission applications.\u003c\/li\u003e\n\u003cli\u003eCustomer must reuse or replace external components like turbo, injectors, and accessories.\u003c\/li\u003e\n\u003cli\u003eRemanufactured with all new or OEM-equivalent internal parts.\u003c\/li\u003e\n\u003cli\u003eBlock is bored for use with oversized pistons.\u003c\/li\u003e\n\u003cli\u003eIncludes a remanufactured, fully rebuilt cylinder head.\u003c\/li\u003e\n\u003cli\u003eTop-end gasket kit is included for installation convenience.\u003c\/li\u003e\n\u003cli\u003eAll machining performed using advanced Rottler CNC equipment.\u003c\/li\u003e\n\u003cli\u003eCore return is required and must pass inspection.\u003c\/li\u003e\n\u003cli\u003eStreet Series is ideal for daily driving and light-duty work.\u003c\/li\u003e\n\u003cli\u003eWarranty coverage is 5 years or 160,000 km (100,000 miles).\u003c\/li\u003e\n\u003cli\u003eProfessional installation is recommended for optimal results.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-start=\"884\" data-end=\"931\"\u003eStreet Series vs Tow\/Haul vs Tow\/Haul HD\u003c\/h3\u003e\n\u003cul data-start=\"933\" data-end=\"1398\"\u003e\n\u003cli data-start=\"933\" data-end=\"1099\"\u003e\n\u003cp data-start=\"935\" data-end=\"1099\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e\u003cstrong data-start=\"935\" data-end=\"952\"\u003eStreet Series\u003c\/strong\u003e:\u003c\/span\u003e\u003cstrong\u003e Ideal for daily driving, light work, and diesel enthusiasts.
