6.0 Powerstroke to Cummins Swap: 2003-2007 Ford
The 2003-2007 Ford Super Duty is a good truck with a 6.0 Powerstroke in it. Pull the 6.0, bolt in a 5.9 or 6.7 Cummins, and keep the cab, frame and transmission you already have.
These kits fit the 2003-2007 F-250, F-350, F-450, F-550 and Excursion. Every part is machined in Blaine, MN, and most orders ship in 1-3 business days.
Pick your 6.0 to Cummins kit
Two things decide the kit: the Cummins you're putting in, and the transmission your truck already has.
| Your Cummins | Your transmission | Kit | Price |
|---|---|---|---|
| Common rail 5.9 or 6.7 (2003-2020) | 5R110 automatic | CR + 5R110 kit | $2,100 |
| 12 or 24 valve 5.9 (1989-2002) | 5R110 automatic | 12/24V + 5R110 kit | $2,025 |
| Common rail 5.9 or 6.7 (2003-2020) | ZF6 6-speed manual | CR + ZF6 kit | $1,550 |
| 12 or 24 valve 5.9 (1989-2002) | ZF6 6-speed manual | 12/24V + ZF6 kit | $1,500 |
What's in a 5R110 kit
- Cummins to Ford 5R110 transmission adapter with a billet steel flexplate
- Motor mounts with 6.4 rubber isolators, pre-installed. You don't have to relocate the factory Cummins ECU.
- 2003-2007 AC/alt bracket that runs your factory Ford AC compressor and alternator, with no AC line changes
What's in a ZF6 kit
- Cummins to Ford 6.0/6.4 ZF6 transmission adapter
- Motor mounts with 6.4 rubber isolators
- The same 2003-2007 AC/alt bracket
The ZF6 kit doesn't include a flywheel. Add the 6.0/6.4 ZF6 machined flywheel ($479), or go with one of the adapter, flywheel and clutch packages below.
ZF6 adapter, flywheel and clutch packages
For 6.0 and 6.4 trucks with the ZF6 S6-750. Each one comes with the adapter plate, a machined flywheel with the Ford pilot bearing installed, a starter spacer if your build needs one, all the hardware and install instructions. Clutches are Kentucky Clutch.
| Package | Common rail Cummins | 12/24V Cummins |
|---|---|---|
| Adapter + flywheel | $1,150 | $1,150 |
| + Stage 1 clutch (350hp) | $1,650 | $1,650 |
| + Stage 2 clutch (450hp) | $1,750 | $1,750 |
| + Stage 3 clutch (650hp dual disc) | $2,395 | $2,395 |
These cover the drivetrain side. You'll still want the motor mounts and AC/alt bracket, so most ZF6 builds start from the kit above.
Other parts a 6.0 swap may need
| Part | When you need it | Price |
|---|---|---|
| 05-10 adjustable pedal throttle bracket, CR Cummins | 2005-2007 trucks with adjustable pedals and a common rail | $449 |
| 05-10 adjustable pedal throttle bracket, 12/24V | 2005-2007 trucks with adjustable pedals and a 1989-2004.5 Cummins | $179 |
| Power steering pump relocation bracket | Moves a Ford 6.4 power steering pump so it clears the steering gearbox on a common rail | $159 |
| 6.0/6.4 starter spacer | Spacing the Ford starter on your adapter | $25 |
Two water inlet gaskets come with every AC/alt bracket, since you'll pull the water inlet to install it. We don't sell wiring, fuel supply lines, intercooler piping or exhaust, so plan on sourcing those. The full swap parts list covers it all.
12/24 valve or common rail in a 6.0 truck?
Both work. The 12 and 24 valve 5.9 are simpler to wire. The common rail makes more power from the factory and is fully electronic, so wiring is a bigger job. Compare the three side by side.
Keep the 5R110 or the ZF6?
Keep what your truck has. These trucks came with the 5R110 TorqShift automatic or the ZF6 6-speed manual, and there's a kit built for each one.
