This isn’t a basic reman, it’s a purpose-built upgrade for 2007.5-2018 6.7L Dodge Cummins owners who want extra pulling power without sacrificing reliability. It’s designed to support up to 600 horsepower, so whether you’re climbing steep grades with a fifth-wheel or cruising cross-country with a heavy load, this engine can handle it. With ceramic-coated pistons and dry film coated skirts, it’s built to take heat and stress in stride. You’ll also get upgraded internals like a Stage 4 camshaft and Manton heavy-duty pushrods, which are perfect for hard-working trucks that never sit still for long. Everything about this long block is engineered to extend the life of your build while giving you the confidence to push it harder. If you depend on your truck every day, this engine is built to keep up.\u003c\/p\u003e\n\u003ch4\u003eThe Right Internal Upgrades Make All The Difference\u003c\/h4\u003e\n\u003cp\u003eThe DFC Tow\/Haul Series takes everything from the Street Series and pushes it to the next level with performance-ready internals built to handle higher loads. Each engine is precision machined with Rottler CNC equipment and bored to accept the next oversized piston, ensuring proper fit and maximum reliability. It features an O-ringed cylinder head for superior sealing, along with a Cometic MLS gasket set to better hold cylinder pressure under extreme conditions. The Stage 4 camshaft enhances valve timing for increased torque, while 103lb heavy-duty valve springs and Manton pushrods help maintain proper valvetrain control under high stress. Ceramic-coated piston crowns and dry film coated skirts increase durability, especially during extended hauling or towing. The block includes ARP 2000 or OptiTorque head studs, depending on availability, to keep the head secure under boosted conditions. Whether you’re building for performance or peace of mind on the job, this long block provides a solid, ready-to-install foundation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fits: \u003c\/strong\u003e 2007.5, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018 Dodge RAM 6.7L Cummins\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for 2007.5-2018 6.7L Dodge Cummins trucks\u003c\/li\u003e\n\u003cli\u003eRated for up to 600 HP at the flywheel\u003c\/li\u003e\n\u003cli\u003eIdeal for towing, hauling, and performance use\u003c\/li\u003e\n\u003cli\u003eIncludes all Street Series upgrades plus additional enhancements\u003c\/li\u003e\n\u003cli\u003eEngine is remanufactured using new OEM or equivalent components\u003c\/li\u003e\n\u003cli\u003eLong block does not include fuel system, turbo, or electronics\u003c\/li\u003e\n\u003cli\u003eIncludes remanufactured cylinder head with new internals\u003c\/li\u003e\n\u003cli\u003eHead studs may be ARP 2000 or OptiTorque depending on stock\u003c\/li\u003e\n\u003cli\u003eBuilt with ceramic-coated pistons and coated skirts for durability\u003c\/li\u003e\n\u003cli\u003eIncludes heavy-duty valvetrain components for higher stress use\u003c\/li\u003e\n\u003cli\u003eComes with a 5 year \/ 100,000 mile (160,000 km) warranty\u003c\/li\u003e\n\u003cli\u003eRequires professional installation for best performance and longevity\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;\"\u003eStreet Series:\u003c\/span\u003e Ideal for daily driving, light work, and diesel enthusiasts.
