Turn A Necessary Rebuild Into A Worthwhile Upgrade

When your 5.9L Cummins needs major engine work, the DFC Diesel KORE590002SOALB gives you a chance to rebuild with more capability instead of simply replacing what wore out. Designed for 2000-2002 Ram 2500 and 3500 24V applications, this KORE Series long block combines an economical remanufactured engine package with Speed of Air technology for owners who want more from their investment. DFC builds the assembly with new Mahle pistons, premium Mahle bearings, Total Seal gapless rings, and a remanufactured cylinder head prepared with new valvetrain components. That makes it a practical fit for a daily driven truck as well as a Cummins that regularly earns its keep hauling equipment or handling commercial workloads. The included front and rear covers, oil pan, preset rockers and pushrods, and complete installation gasket kit also mean fewer major pieces need to be gathered before installation can move forward. Compatibility with most existing components and upgrades helps make the transition easier when you are transferring usable hardware from the original engine. With DFC backing the KORE Series with a 5 year or 160000 kilometer warranty, this long block offers a compelling balance of value, upgraded technology, and carefully selected components for putting your Cummins back into service.

Careful Machining Builds Confidence Into Every Cylinder

The foundation of the KORE590002SOALB begins with a professionally machined 5.9L Cummins block that is bored for the next oversized piston without using cylinder sleeves. DFC uses advanced Rottler equipment including the Rottler F69 ATC to blueprint cylinder blocks to tolerances the manufacturer states are tighter than OEM specifications. Inside the block, new Mahle pistons work alongside Total Seal gapless rings and new Mahle main and rod bearings to establish a fresh rotating and reciprocating assembly. This configuration also incorporates Speed of Air piston technology, adding a specialized approach to combustion performance within the familiar 24V Cummins platform. The remanufactured cylinder head is resurfaced and magnafluxed before receiving new valves, seats, guides, stem seals, and other valvetrain components needed for consistent operation. Improved gasket sealing methods address common leakage areas, while an available MLS head gasket upgrade provides another option when planning the engine configuration. With the rockers and pushrods preset to factory specifications and a complete gasket set included for installation, DFC delivers a prepared long block that reduces assembly work while retaining the flexibility to reuse many compatible external components.
