Keep Your Proven Cummins Doing What It Does Best

A good truck is worth keeping around, and an engine problem should not automatically mean giving up on a Ram that still has plenty of useful life left. The DFC Diesel KORE5904507AULB KORE Series Long Block offers 2004.5-2007 Ram 2500 and 3500 owners a cost conscious replacement specifically configured for 325 horsepower automatic applications. Instead of taking a chance on an unknown used engine, you get a professionally prepared assembly filled with new Mahle pistons, Mahle bearings, Total Seal gapless rings, and other fresh internal components. The remanufactured cylinder head is already included, giving you a more complete starting point when the goal is to get a daily driver or working truck back into dependable service. DFC also supplies the front and rear covers, oil pan, and preset rockers and pushrods, which can save your shop time spent sourcing and setting up major pieces individually. A complete installation gasket kit helps round out the package, while compatibility with most existing components and upgrades makes it easier to reuse suitable hardware from your current engine. With DFC advertising a 5 year or 160000 kilometer warranty, this KORE Series long block delivers an appealing balance of replacement value and carefully selected components for owners who plan on keeping their Cummins working.

Precision Preparation Goes Deeper Than Fresh Parts

The KORE5904507AULB is built around a professionally machined 5.9L Cummins block prepared with advanced Rottler equipment for accurate and repeatable engine dimensions. DFC uses its Rottler F69 ATC to blueprint cylinder blocks to tolerances the manufacturer states are tighter than OEM specifications, creating a carefully controlled foundation for the internal assembly. New Mahle pistons operate with Total Seal gapless rings and new Mahle main and rod bearings, replacing several critical wear components before the engine returns to service. The remanufactured cylinder head receives new valves, springs, hardened seats, stem seals, and cast guides to refresh important areas of the valvetrain. Improved gasket sealing methods are used around common leakage areas, and an MLS head gasket upgrade is available for customers who want that option incorporated into their build. New front and rear main seals are also included, while the rockers and pushrods arrive preset to factory specifications to reduce additional valvetrain setup during installation. For a 2004.5-2007 Ram equipped with the 325 horsepower automatic 5.9L Cummins configuration, these machining processes and new components provide a thoroughly prepared long block for the next chapter of the truck's service life.
