Why the Cummins Swap Is Worth It
- The 6.0 has well-documented reliability problems that get expensive fast.
- A 5.9 or 6.7 Cummins is one of the most over-engineered diesel engines ever built.
- The 2003 to 2007 Super Duty body, frame, and interior are excellent platforms.
- Resale value of a clean Cummins-swapped 6.0 truck is often higher than a stock 6.0.
Engine Choices
For 2003 to 2007 Super Duty swaps, the 5.9L Common Rail Cummins (2003 to 2007) is the most popular option. It matches the era of the truck electronically, makes good power from the factory, and is straightforward to find used. The 12V and 24V also work if you want simpler wiring.
Transmission Options
- 5R110 TorqShift automatic — the factory 5-speed auto in 2003-2010 Super Duty. Our most popular kit. Use a billet flexplate.
- ZF6 manual (S6-750) — factory 6-speed in some trims. Strong, simple.
- Aftermarket swap — NV5600, ZF6, or built 5R110.
What You'll Need
- An adapter plate (12V/24V or CR to ZF6 or 5R110).
- Billet flywheel or flexplate.
- 99-07 Super Duty motor mounts.
- AC/alternator bracket using the factory 6.0 AC compressor and alternator.
- Throttle pedal adapter for CR builds.
- Wiring harness and fuel plumbing.
