5.9L Cummins Stage 2 Long Block Engine (2003-2007) - Industrial Injection - PDM-59RLB

Industrial Injection 5.9L Cummins Stage 2 Long Block Engine ( 2003-2007)
The Industrial Injection Stage 2 Long Block Engine is built for 2003-2007 Dodge Ram 5.9L Cummins Common Rail owners looking to push performance to the next level while maintaining the durability required for competitive diesel applications. Featuring premium forged components, advanced machining processes, and race-proven engineering, this engine is designed to deliver exceptional horsepower, reliability, and longevity under extreme operating conditions.
Every Stage 2 Long Block starts with a balanced and blueprinted rotating assembly that is Sim-tested to ensure maximum precision and reliability. The bottom end is strengthened with Wagler HD Forged Connecting Rods, Industrial Injection X Series Fly Cut, Coated and Chamfered Pistons, a 14mm Gorilla Girdle with ARP Main Studs, and a balanced Cummins crankshaft to provide the strength required for high-horsepower builds.
The valvetrain is upgraded with an Industrial Injection Stage 2 210/220 Camshaft and cam bearings installed in every journal to help prevent camshaft and block wear. Coated H-Series bearings, billet freeze plugs, new tappets, and a complete oiling and cooling system refresh ensure long-term durability and performance.
Topping off the build is a fully CNC Ported and Polished Stage 2 Cylinder Head with Fire Ring Grooves. Featuring a machined intake shelf for a performance intake runner, premium stainless steel nitride-coated valves, oversized valve seats, hardened alloy valve guides, drilled and tapped coolant freeze plugs, and USA-made 120lb valve springs, this cylinder head is engineered to maximize airflow and head gasket sealing under high boost and cylinder pressure.
To complete the package, ARP 625 Head Studs provide exceptional clamping force for high-performance and competition applications.
