*Discontinued* DFC Diesel Remanufactured Short Block Crate Engine

The DFC Short Block is the perfect option for any 6.6L Duramax LB7 owner who wants to replace their tired or high mileage engine. During the remanufacturing process DFC makes important improvements so your engine maintains extreme durability even in applications pushing higher than stock horsepower. DFC focused on common oiling issues, such as adding an EDM oil pump shaft with a hardened dowel installed to prevent slipping and the risk of an oil pressure loss. Every DFC engine is remanufactured to the most strict guidelines to provide you with a dependable option when you need an engine replacement. All DFC engines are machined using Rottler equipment that allows DFC to build to engines with tighter tolerances that are more precise specifications than OEM, which will help these engines last for years to come.

The DFC short block is machined with near identical weight piston and connecting rod assemblies to help you get a smoother running engine that makes less noise and is more balanced.  DFC short blocks include reinforced internals with new pistons, rings, doweled oil pump, bearings, and rods. 

DFC engines are remanufactured by diesel enthusiasts for diesel enthusiasts. DFC stands behind their products with one of the industry’s leading 5 year 100,000 mile warranty (Non-Commercial).
