Features:
If your 1998 5.9L Cummins-powered Ram is built to tow hard, run strong, and take abuse without flinching, the DFC Diesel TH591998SOALB Tow/Haul Series Long Block is the foundation you want under the hood. Designed specifically for the 24-valve Storm Block, this engine doesn’t just replace your worn-out setup—it upgrades it with proven performance features made for high-load use. Whether you’re pulling trailers day in and day out or want a bulletproof long block for your next build, this package is built to handle up to 700 horsepower while keeping things reliable enough for daily duty. And unlike a basic reman, everything inside has been carefully selected, machined, and assembled to tighter tolerances using name-brand components you can trust.
This build includes everything from the Street Series—like Total Seal gapless rings, Cometic MLS head gaskets, and either ARP or OptiTorque head studs—but adds a host of enhancements built specifically for towing and high-performance applications. A stage 3 camshaft improves airflow and midrange torque, while 60lb heavy-duty valve springs and Manton HD pushrods keep the top end in check under boost. The pistons are treated with ceramic-coated crowns and dry film coated skirts to manage heat and reduce wear—two must-haves in high-output, high-stress builds. From the rear aluminum freeze plug to the resurfaced and magnafluxed cylinder head, every inch of this long block is engineered with purpose. And with a 5-year/160,000 km (100,000 mi) warranty, you’ve got long-term peace of mind to match the engine’s capability. This is the long block that lets your Cummins work as hard as you do.
