Ready for Big Power and Real-World Work

If your 2000–2002 Dodge Ram 5.9L Cummins 24V is built for more than grocery runs—if it’s towing heavy loads, seeing long highway pulls, or putting down serious horsepower—then the DFC Diesel Tow/Haul HD Series Long Block is the engine built to handle that lifestyle. Designed for drivers pushing up to 900 HP but still needing street manners and daily drivability, this package combines proven reliability with performance-ready components. It starts with everything in the Street and Tow/Haul Series—like Speed of Air™ Hyperformance pistons for better combustion and lower EGTs, Total Seal gapless rings, and heavy-duty valvetrain upgrades. But this HD version steps up with serious internals, including Wagler connecting rods, a Fluidamper harmonic balancer, and a heavy-duty flexplate—all tied together with a fully balanced rotating assembly to handle torque and stress that would chew through lesser builds.

Strength Where It Counts, Backed with Confidence

Every part of this engine is selected to deliver lasting strength under high load, high boost, and heavy work. Whether you're pulling a multi-axle trailer across mountain passes or running a high-performance tune, this long block is built to hold up and stay cool doing it. The Fluidamper reduces harmful vibrations at high RPM, the Wagler rods provide bulletproof bottom-end strength, and the HD flexplate ensures clean, reliable power delivery under strain. With aerospace coatings on the piston crowns and skirts, combustion stays efficient and controlled—meaning fewer regens, cleaner oil, and better longevity overall. The result is a smoother, more responsive engine that feels powerful without being overworked. DFC includes a 5-year, 100,000-mile warranty even on this severe-duty build—just follow the maintenance guidelines and this engine will keep pulling, climbing, and hauling long after others have given up. If you want extreme strength with daily dependability, this HD Long Block is the one to beat.
