An Affordable Path Back To A Dependable 24 Valve

A worn out 1998.5-1999 Dodge 5.9L Cummins doesn't have to mean an expensive engine replacement or a risky gamble on a used unit. The DFC Diesel KORE Series Long Block was built specifically to bridge that gap, giving Ram 2500 and 3500 owners a quality remanufactured engine at a more accessible price point. DFC keeps costs down by leaving out components that are commonly reused or easily sourced separately, without cutting any corners on the actual remanufacturing process itself. Every long block is machined using Rottler equipment, some of the most advanced machining technology in North America, resulting in tolerances that exceed original OEM specifications. Inside, you're getting all new pistons, rings, bearings, gaskets, seals, valves, springs, hardened seats, stem seals, and cast guides, along with a standard Cometic MLS head gasket and Total Seal gapless piston rings. DFC also builds in improved gasket sealing methods specifically targeting the common leak points these early 24 valve engines are known for. Whether you're keeping a work truck running or restoring a reliable daily driver, this long block gives you real remanufactured quality without paying for a full engine package. It's a smart, budget-conscious way to get real miles back out of this short-production transition-year Cummins.

Precision Machining With Purposeful Upgrades To Known Weak Points

The DFC Diesel KORE5998599LB is a remanufactured long block engineered specifically for 1998.5-1999 Dodge Ram trucks equipped with the 5.9L Cummins 24 valve engine featuring the trigger gear crankshaft, compatible with both automatic and manual transmission applications. Every long block is machined using Rottler equipment, delivering tolerances that exceed OEM specifications throughout the build. The engine includes all new pistons, rings, bearings, gaskets, seals, valves, springs, hardened seats, stem seals, and cast guides, and comes standard with a Cometic MLS head gasket paired with Total Seal gapless piston rings for improved sealing performance. DFC also incorporates improved gasket sealing methods in the areas most prone to leakage on this platform. The long block ships as a complete short block assembly with the cylinder head included, along with a complete top end gasket kit and silicone to finish the installation. It's worth noting this long block does not include the front cover, oil pump, CP3 or injection pump gear, oil pan, oil pickup tube, rear main seal retainer, rocker arms, valve bridges, or pushrods, since these are commonly reused or sourced separately by the installer. Every engine is manufactured in an ISO 9001:2015 certified facility and backed by a 1 year, unlimited mileage manufacturer warranty.
