Putting a DFC Diesel Remanufactured Long Block Crate Engine in your 2001-2004 GM 6.6L Duramax LB7 is a cost-effective alternative to buying a whole new truck! Each remanufactured engine is built to give you a dependable and durable replacement for your tuck. During the remanufacturing process, DFC makes crucial improvements to help your engine last, even in applications with increased horsepower. For example, each engine features an EDM oil pump shaft with a hardened dowel installed to prevent slipping and the risk of an oil pressure loss. DFC uses Rottler machining equipment to ensure that each engine is built to tolerances that are more precise than OEM specifications for a more efficient and longer lasting engine.
 
Engine Remanufacturing 
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. 

Cylinder Head
Unlike some others in the industry that re-use wearing items like valves guides, DFC replaces each one with a new cast guide in every cylinder head. Instead of just re-grinding and reusing valves like other companies, DFC installs all new valves from high quality sources like MAHLE or SBI.

Warranty
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). 

DFC 6.6L Long Block Includes
Complete short block with the front cover and seal, rear cover with main seal, oil pan, all new internal components, cylinder heads with all rockers and pushrods installed, doweled oil pump gear, woodruff keyed camshaft and complete gasket kit for installation.

FEATURES:
  • Remanufactured Long Block Engine 
  • Upgraded EDM Oil Pump Shaft & Hardened Dowel Pin
  • Improved Gasket Sealing Methods In Common Leak Areas

Application Note: 
The specific brand of each component may change due to part availability at the time of each build. Parts are chosen at the discretion of DFC and cannot be specially requested.
