The DFC Diesel Tow/Haul Series engine comes standard with all the upgrades found in the Street Series model as well as several enhancements to make this engine perfect for towing, hauling and performance applications up to 700 HP.

Oil Pump

All DFC 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.

Machining

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.

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 long blocks come with new head bolts, revised torque sequences and digitally recorded torque values to ensure reliability.

Core Criteria

Ensuring every engine is built to the same high quality standards as the next DFC is very strict on what is remanufactured rejecting components that require considerable “restoring” to acceptable specifications.

Valve Springs

Instead of just testing old springs and reusing like most remanufactures DFC installs brand new SBI valve springs that are still tested for proper spring pressure on every cylinder head we rebuild.

Valves

DFC installs new valves from MAHLE/Clevite or SBI in every cylinder head we remanufacture. Most companies will re-grind and install used again.

Cast Guides

Common industry practice is to check guide clearance and if within specification, not replace. DFC considers this practice unacceptable and installs new cast SBI guides in every cylinder head we remanufacture.

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.

Torque Specs

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.

Oil Cooler

Highly recommended to replace it but MANDATORY if your engine had a bearing failure.

Injectors

Recommended to be replaced if the engine had in excess of 160,000km (100,000mi) but MANDATORY IF:

  • The engine cut a hole in or melted a piston,
  • The truck had contaminated fuel,
  • If you are not going to test your old injectors before re-installation.
Turbo

Recommended to be replaced if in excess of 200,000km (125,000mi) but MANDATORY IF:

  • Engine had debris go through cylinders,
  • Turbocharger shaft has end play,
  • Engine was dusted.
Water Pump

Recommended to replace it - especially if the engine had in excess of 200,000km (125,000 mi).

Evans Waterless Coolant

Upgrade to waterless coolant for:

  • Increased reliability
  • Prevent corrosion & boil over
  • Improve engine performance
