The DFC Diesel Remanufactured KORE Series Long Block Crate Engine is an affordable replacement for the worn diesel in your 2004.5-2007 Dodge 5.9L Diesel. The KORE Series of engines were designed to bridge the gap for Ram 2500/3500 owners that want a quality engine but are working on a tighter budget. These engines are built to the same high standards and quality of DFC's regular engines and include numerous upgrades to the common failure areas. The KORE Series engines give you an excellent build but reduce costs by not including items that can often be re-used or easily sourced by the end user.

Engine Remanufacturing

These engines are machined utilizing some of the most advanced machining equipment in North America. This Rottler equipment helps ensure the engines feature tolerances that are better than OEM specifications. In addition, the Kore Series features all new pistons, rings, bearings, gaskets, seals, valves, springs, hardened seats, stem seals, and cast guides. Engines come standard with a Cometic MLS Head Gasket, Total Seal Gapless Piston Rings, and incorporate improved gasket sealing methods in common leakage areas.


DFC engines are remanufactured by diesel enthusiasts for diesel enthusiasts. DFC stands behind the KORE Series of engines with a 1-year Unlimited-Mileage Warranty (Non-Commercial).

Complete short block assembly and gaskets, plus cylinder head. A complete top end gasket kit is included to finish install.
