DURAMAX STREET SERIES
Authorized Dealer of DFC DIESEL engines
The street series of engines are DFC Diesel’s flagship product. Built for work trucks, daily drivers and the diesel enthusiast in mind these engines are a vast improvement from stock as they contain important upgrades to common problem areas. With the majority of Dodge, Ford and Chevy truck owners having some form or another of aftermarket upgrades done, DFC Diesel has remanufactured all of our engines with the highest quality duramax diesel parts. Your engine will perform flawlessly with added horsepower and still backed with one of the industry leading warranties in North America.
THE DFC DIESEL DIFFERENCE
QUALITY PRECISION REPEATABLE DEPENDABLE
• Comes standard with 5 yr 160,000 km (100,000 mi) parts and labor warranty
• Custom EDM keyed oil pump preventing oil pressure loss
• Cylinder blocks are blueprinted to tighter tolerances than OEM specifications using our Rottler F69 ATC
All DFC Diesel Duramax engines feature an EDM doweled oil pump shaft with a hardened dowel installed locating the gear to the oil pump shaft preventing slipping and the subsequent oil pressure loss.
Head Gasket Sealing
Some model years of Duramax engines are more susceptible to premature head gasket failure. To reduce the chance of this all DFC Diesel long blocks come with new head bolts, revised torque sequences and digitally recorded torque values to ensure reliability.
Instead of just testing old springs and reusing like most remanufactures DFC Diesel installs brand new SBI valve springs that are still tested for proper spring pressure on every cylinder head we rebuild.
Common industry practice is to check guide clearance and if within specification, not replace. DFC Diesel considers this practice unacceptable and installs new cast SBI guides in every cylinder head we remanufacture.
These engines use many torque to yield fasteners that require bolt “stretch” to maintain adequate clamp loads. In addition to not just following the OEM procedures for tightening sequence our assembly technicians record the achieved torque load through use of digital torque wrenches ensuring no fastener will come loose over time.
Our Rottler equipment allows us to remanufacture the Duramax engine’s to tighter than OEM specifications resulting in a longer lasting more efficient engine assembly.
Ensuring every engine is built to the same high quality standards as the next DFC Diesel is very strict on what is remanufactured rejecting components that require considerable “restoring” to acceptable specifications.
DFC Diesel installs new valves from MAHLE/Clevite or SBI in every cylinder head we remanufacture. Most companies will re-grind and install used again.
Weighed Rotating Assemblies
Our production engines are typically matched with near identical weight piston and connecting rod assemblies giving our customers a smoother running and quieter engine.
