When You Need Power That Won’t Back Down

If your 2004-2005 RAM 2500 or 3500 with a 5.9L Cummins is ready for a serious upgrade, the D&J Heavy Hauler Ready Run Engine is built to handle just about anything you can throw at it. Whether you're pulling a loaded trailer through the mountains or stacking miles on the highway, this engine brings dependable strength with up to 700 horsepower on tap. The included BD Screamer turbocharger gives you fast spool-up and strong mid-range punch, while the heavy-duty two-piece manifold handles high heat without breaking a sweat. Everything comes pre-lubed and fully assembled, making installation a lot smoother for shops and experienced DIYers alike. D&J includes all the key components you'd expect in a top-tier build, like a new water pump, sensors, fuel lines, and even break-in oil, so you’re not left chasing parts. It's a purpose-built powerplant designed for heavy use and long-term reliability. And with a 24-month, 100,000-mile warranty backing it, this is a drop-in solution you can trust every time you turn the key.

This Engine Is Built With Purpose In Every Pass

From the first teardown to the final bolt, the Heavy Hauler Ready Run Engine is all about precision. D&J starts by completely disassembling and inspecting every component, crack-checking, blasting, and cleaning the long block before any machining is done. The block is CNC bored, line bored, and torque plate honed to ensure perfect cylinder geometry and ring seal. The included Stage 1 head is equally refined, featuring 5-axis CNC porting, oversized valve seats, and a precision multi-angle valve job to maximize airflow and combustion efficiency. ARP 9/16-inch head studs are torqued to 175 ft-lbs for unbeatable clamping strength, helping to keep everything sealed under high boost. BD's high-pressure fuel system, including a reman CP3 pump and 15HP StockPlus injectors, ensures consistent fueling and cleaner combustion across the powerband. Every engine is blueprinted, balanced, and assembled with proper clearances, giving you the kind of performance and durability you won’t get from a basic rebuild. It's a serious upgrade for anyone who needs their Cummins to perform under pressure.
