Designed for workhorses that live on the job site or haul heavy loads on the regular, it brings all the muscle you need without cutting corners. Built for up to 700 horsepower, this long block includes internal upgrades like a Stage 3 camshaft and Total Seal gapless piston rings that help improve power delivery and reduce blow-by. Manton HD push rods and heavy-duty valve springs give the valvetrain extra stability under pressure, keeping performance smooth when it matters most. The pistons are ceramic coated to handle high temperatures, while the dry film coating on the skirts helps reduce friction and wear over time. Whether you're towing a fifth wheel or loading down a flatbed, this engine is built to stay strong under stress. And with a 5-year, 160,000 km warranty behind it, you can hit the road with peace of mind and zero hesitation.\u003c\/p\u003e\n\u003ch4\u003ePrecision Built For Long Term Durability And Power\u003c\/h4\u003e\n\u003cp\u003eEvery detail of the DFC Diesel Tow\/Haul Series Standard Long Block is engineered to meet or exceed OEM standards, ensuring a rock-solid foundation for your Cummins build. The block is bored and machined for over-sized pistons, then fitted with new OEM or equivalent internals to restore factory performance with added strength. Cylinder heads are fully remanufactured with new valves, guides, and seats, plus they’re resurfaced and magnafluxed to confirm structural integrity. Rottler CNC machining ensures tight tolerances from top to bottom, which is crucial for long-term reliability and consistent power delivery. The use of ARP Series 2000 or OptiTorque head studs provides exceptional clamping force to secure the top end under boost. A Cometic MLS head gasket adds another layer of reliability by sealing in combustion pressures under heavy load. Paired with the Stage 3 camshaft and upgraded valvetrain, this long block is ready to handle high-stress applications without flinching. It's a complete, drop-in-ready package for builders who value craftsmanship and consistency.\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\u003eDesigned for 2004.5-2007 5.9L Dodge Cummins applications\u003c\/li\u003e\n\u003cli\u003eStandard transmission compatibility only, not for automatic\u003c\/li\u003e\n\u003cli\u003eBuilt for towing, hauling, and performance up to 700 HP\u003c\/li\u003e\n\u003cli\u003eIncludes both short block and remanufactured cylinder head\u003c\/li\u003e\n\u003cli\u003eAll components meet or exceed OEM specifications\u003c\/li\u003e\n\u003cli\u003eHead studs brand may vary based on availability\u003c\/li\u003e\n\u003cli\u003eValve spring rating varies by model year range\u003c\/li\u003e\n\u003cli\u003eRequires professional installation and proper break-in\u003c\/li\u003e\n\u003cli\u003eMachined using Rottler CNC for precision and reliability\u003c\/li\u003e\n\u003cli\u003eBacked by a 5-year or 160,000 km warranty\u003c\/li\u003e\n\u003cli\u003eEngine build includes upgraded internals for longevity\u003c\/li\u003e\n\u003cli\u003eDesigned to be a direct-fit long block replacement\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;\"\u003eStreet Series:\u003c\/span\u003e Ideal for daily driving, light work, and diesel enthusiasts.
