Built for diesel drivers who expect more than factory performance, this remanufactured engine is all about delivering reliability you can count on, whether you're hauling gear to the jobsite or running weekend errands with a trailer in tow. The Street Series isn’t just a basic rebuild, it's loaded with upgrades in all the right places. You'll get ARP or OptiTorque head studs for improved clamping strength, plus Total Seal gapless piston rings that hold compression better than stock. That means more efficient combustion, less blow-by, and a tighter, cleaner-running engine overall. Even the oil pump gear has been upgraded with DFC’s custom EDM doweling for better long-term reliability under high-load conditions. And with a 5-year, 160,000-kilometer warranty that backs it all, this engine is clearly built to last. It’s the kind of peace of mind you want under the hood when your truck has a job to do.\u003c\/p\u003e\n\u003ch4\u003ePrecision Remanufacturing That Exceeds Factory Expectations\u003c\/h4\u003e\n\u003cp\u003eEvery component in the DFC Diesel SS6607510LMMSOALB Street Series Long Block is carefully remanufactured to meet and exceed original OEM specs. The block is professionally machined and bored to accept next oversized pistons, which are brand new along with the rings, bearings, and gaskets. Cylinder heads are resurfaced, magnafluxed for cracks, and fully rebuilt with new seats, guides, valves, and stem seals to ensure optimal airflow and combustion. This engine also features DFC’s upgraded sealing process in common leak-prone areas, improving long-term durability. The camshaft is secured with a Woodruff key for better timing retention, while high-tensile head studs help maintain proper sealing under higher cylinder pressures. Everything from the rockers to the pushrods is preset to factory spec, making installation easier and more streamlined. From the advanced Rottler machining equipment to the name-brand internals, this engine is built with top-tier components that work together to extend service life and enhance overall performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fits: \u003c\/strong\u003e 2007.5, 2008, 2009, 2010 GM\/Chevrolet 2500HD\/3500HD 6.6L Duramax LMM\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt for 2007.5–2010 GM\/Chevy 2500HD and 3500HD with 6.6L Duramax LMM\u003c\/li\u003e\n\u003cli\u003eDesigned as a direct long block replacement for trucks with standard or automatic transmissions\u003c\/li\u003e\n\u003cli\u003eIntended for daily drivers, work trucks, and diesel enthusiasts\u003c\/li\u003e\n\u003cli\u003eIncludes short block, cylinder heads, and full top-end gasket kit\u003c\/li\u003e\n\u003cli\u003eDoes not include fuel system, turbo, or electronics\u003c\/li\u003e\n\u003cli\u003eCore return is typically required by the manufacturer\u003c\/li\u003e\n\u003cli\u003eARP or OptiTorque head studs included based on current availability\u003c\/li\u003e\n\u003cli\u003eAll internal components are new or reconditioned to exceed OEM standards\u003c\/li\u003e\n\u003cli\u003eEngine is pre-set to factory specs for easier installation\u003c\/li\u003e\n\u003cli\u003eWarranty covers 5 years or 160,000 kilometers (100,000 miles)\u003c\/li\u003e\n\u003cli\u003eIdeal for customers looking to upgrade known weak points in the factory engine\u003c\/li\u003e\n\u003cli\u003eProfessional installation is recommended for proper performance and warranty validation\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\u003cstrong\u003e\u003cspan style=\"text-decoration: underline;\"\u003eStreet Series:\u003c\/span\u003e Ideal for daily driving, light work, and diesel enthusiasts.
