DFC Diesel Remanufactured KORE Series 6.6 LLY Long Block Crate Engine (With Callies Crankshaft)

The DFC Diesel Remanufactured KORE Series 6.6 LLY Long Block Crate Engine (With Callies Crankshaft) from XDP is a cost-effective replacement for the failed engine in your 2004.5-2005 GM 6.6L Duramax LLY equipped pickup truck. It is designed to meet the needs of Chevy/GMC owners who want a high-quality engine but have a tighter budget. These engines are built to the same high standards and quality as DFC's regular engines. They also include upgrades to the common failure areas. The KORE Series is a more affordable option because it does not include many components that can be re-used from your existing engine or easily sourced by the end user. 

DFC engines are built 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 Total Seal Gapless Piston Rings and incorporate improved gasket sealing methods in common leakage areas. 

The included Compstar-Durastar crankshaft from Callies features a Deep DuraCase nitride treatment that enhances durability and wear.  Rod journals are drilled for reduced inertia and ease of balance. All journals feature True Form fillet radii and the timing gear is keyed to prevent shearing. These journals are also polished to a 6Ra or finer finish. The stroke is 3.898" with OEM journal diameters and width. Callies constructs this crankshaft through hardened 4340 steel. The damper fit is dual keyed. This crankshaft accepts OEM post and flange bolts in addition to OEM flywheels/flexplates. The main bearing oil holes have lead-ins for enhanced cold start oil flow to rod journals.
