This isn’t your average reman. It’s a purpose-driven long block designed for truck owners who live in the 650–800 horsepower range, but still want the ability to stretch up to 900 HP at the flywheel. Whether you’re pulling a loaded trailer over the pass or dialing in your tune for weekend performance, this long block is built to handle it all without flinching.\u003c\/p\u003e\n\u003ch4\u003eSerious Hardware Where It Counts\u003c\/h4\u003e\n\u003cp\u003eAt the heart of the Tow\/Haul HD build are Wagler connecting rods, a balanced rotating assembly, and a Fluidamper harmonic balancer—all premium upgrades over even the Tow\/Haul standard. DFC didn’t stop there; a heavy-duty flexplate and a set of ceramic-coated pistons with dry film-coated skirts come standard to handle the heat and pressure of high-load applications. Like all DFC engines, it’s machined with industry-leading Rottler equipment and assembled using all new OEM or better components, including Total Seal gapless rings, a Cometic MLS head gasket, and either ARP or OptiTorque head studs. From street use to full-load towing, this engine is built to do it all—and do it reliably. Backed by DFC’s 5-year\/160,000 km warranty, it’s the peace of mind you need when your Cummins is built to perform.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e 1998 Dodge RAM 5.9L Cummins\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Image Note:\u003c\/strong\u003e Some images may be representative.\u003c\/p\u003e","brand":"DFC Diesel","offers":[{"title":"Default Title","offer_id":68060707520785,"sku":"DDU-TH591998SOALBHD","price":19057.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0477\/1089\/files\/DDUTH591998SOALBHD_1.jpg?v=1794721876","url":"https:\/\/gautoparts.com\/products\/dfc-diesel-th591998soalbhd-tow-haul-hd-series-speed-of-air-long-block-std-auto-1998-ram-5-9l-cummins-24v-storm-block","provider":"Guaranteed Auto Parts","version":"1.0","type":"link"}
