Each unit is carefully machined using Rottler CNC equipment to ensure accurate tolerances and clean mating surfaces throughout the assembly. The block is bored for over-sized pistons and assembled with all new internals, including pistons, rings, bearings, gaskets, and seals. ARP Series 2000 or OptiTorque head studs are used for maximum clamping force, depending on availability. A Cometic multi-layer steel head gasket comes standard, providing exceptional sealing under high load and temperature. The cylinder head is fully remanufactured with new valves, guides, springs, and seats, then resurfaced and magnafluxed to confirm structural integrity. This long block also includes enhanced piston cooling and improved sealing at factory weak points, giving it a strong edge over typical rebuilds. It's a solid, dependable solution for any Cummins owner who wants power they can count on every day.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fits: \u003c\/strong\u003e 2007.5, 2008, 2009, 2010, 2011, 2012 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 2007.5-2012 6.7L Dodge Cummins engines\u003c\/li\u003e\n\u003cli\u003eCompatible with both standard and automatic transmissions\u003c\/li\u003e\n\u003cli\u003eBuilt for daily drivers, work trucks, and diesel enthusiasts\u003c\/li\u003e\n\u003cli\u003eImproves upon common failure points found in stock engines\u003c\/li\u003e\n\u003cli\u003eUses all new name-brand internal components\u003c\/li\u003e\n\u003cli\u003eIncludes ARP or OptiTorque head studs depending on availability\u003c\/li\u003e\n\u003cli\u003eComes standard with Cometic MLS head gasket for better sealing\u003c\/li\u003e\n\u003cli\u003eTotal Seal gapless rings included for improved compression\u003c\/li\u003e\n\u003cli\u003eEnhanced piston cooling to reduce damage from faulty injectors\u003c\/li\u003e\n\u003cli\u003eMachined using high-precision Rottler CNC equipment\u003c\/li\u003e\n\u003cli\u003eIncludes complete top-end gasket kit for installation\u003c\/li\u003e\n\u003cli\u003eBacked by a 5-year or 160,000 km limited warranty\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.
