Built with the everyday diesel enthusiast in mind, this engine is ideal for work trucks, daily drivers, and anyone who needs something tougher than stock. It comes packed with upgrades to fix the common trouble spots most Cummins owners run into over time, like head gasket issues and piston failures. You get premium components like ARP or OptiTorque head studs, a high-performance Cometic MLS head gasket, and Total Seal gapless rings that give you tighter sealing and longer engine life. This long block is more than just a rebuild, it’s a real upgrade over factory specs, using only new, name-brand parts that meet or exceed OEM standards. And with a 5-year, 100,000-mile warranty, you know this thing is built to handle serious use without giving up on you. Whether you’re hauling gear to the jobsite or towing your toys out to the dunes, this engine brings the confidence you want every time you hit the key.\u003c\/p\u003e\n\u003ch4\u003eEngineered With Precision For Daily Performance And Longevity\u003c\/h4\u003e\n\u003cp\u003eUnder the hood, the Street Series Long Block is all about solid craftsmanship and high-end components that work together seamlessly. Each unit is Rottler CNC-machined for exact tolerances, bored to accept oversized pistons, and assembled with meticulous attention to detail. The block includes all-new pistons, rings, bearings, gaskets, and seals, plus a remanufactured cylinder head that’s fully rebuilt with new valves, guides, seats, and stem seals. Even the rocker arms and pushrods are pre-set to factory specs so installation is straightforward and stress-free. This long block is engineered to reduce piston cooling issues, which helps prevent the kind of failures caused by injector problems in high-mileage engines. The Total Seal gapless piston rings reduce blow-by and oil consumption while maintaining strong compression under load. From top to bottom, this Street Series model is designed to provide smooth, reliable performance for years, making it the perfect solution for those who want upgraded durability without going full race build.\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 remanufactured long block, not a complete engine.\u003c\/li\u003e\n\u003cli\u003eStreet Series is best suited for daily drivers and light-duty work trucks.\u003c\/li\u003e\n\u003cli\u003eBuilt to correct known failure points common in 5.9L Cummins engines.\u003c\/li\u003e\n\u003cli\u003eComes preset with rockers and pushrods to factory specs for easier installation.\u003c\/li\u003e\n\u003cli\u003eUses oversized pistons that require matching bore specifications.\u003c\/li\u003e\n\u003cli\u003eRequires transferring some components like the turbo, injection pump, and accessories from your existing engine.\u003c\/li\u003e\n\u003cli\u003eCompatible with both standard and automatic transmissions.\u003c\/li\u003e\n\u003cli\u003eMachined and assembled in North America using Rottler CNC equipment.\u003c\/li\u003e\n\u003cli\u003eAll parts are new or OEM-equivalent, no recycled internals used.\u003c\/li\u003e\n\u003cli\u003eBacked by a 5-year, 160,000 km (100,000 mi) limited warranty.\u003c\/li\u003e\n\u003cli\u003eCore return is required and may be subject to inspection for acceptance.\u003c\/li\u003e\n\u003cli\u003eIntended for vehicles built between mid-2004 and 2007 with the 5.9L Cummins platform.\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;\"\u003e\u003cstrong data-end=\"952\" data-start=\"935\"\u003eStreet Series\u003c\/strong\u003e:\u003c\/span\u003e\u003cstrong\u003e Ideal for daily driving, light work, and diesel enthusiasts.
