These Ford-specific kits focus on clean packaging, service access, and reliable routing for Super Duty engine bays. CAD-modeled castings, brackets, and charge-air plumbing help the turbo operate in its efficiency range for towing and daily use. Choose components to match your goals—quick response for towing, balanced street manners, or added airflow for higher-fuel builds.
Enthusiasts choose the Fummins swap for torque, longevity, and easy power. A 5.9 or 6.7 Cummins can turn a Super Duty into a reliable tow rig or a strong daily that still sips fuel.
Contents vary by year and configuration. A typical kit may include a turbocharger option sized for your goals, an exhaust manifold or adapter, hot-pipe and charge-air plumbing, oil feed/return solutions, clamps, couplers, brackets, heat shielding, and hardware. See each product listing for the exact bill of materials, actuator provisions, and sensor porting.

A Fummins conversion installs a Cummins diesel engine into a Ford Super Duty truck. Builders choose Fummins swaps to combine the strength and comfort of a Ford chassis with the torque, reliability, and long service life of a Cummins engine. The result is a truck that tows harder, runs cooler under load, and is easier to service long-term than many factory powertrains.
The best Cummins for a Fummins swap depends on budget and goals. A 12-valve Cummins is popular for simplicity and reliability. A 24-valve common-rail offers easier tuning and strong towing manners. A properly sized 6.7 Cummins provides maximum torque and modern drivability when cooling, gearing, and turbo selection are matched correctly to the Ford platform.
Yes. When properly installed and sized, a Fummins conversion can be daily driven and excels at towing. Many owners report improved low-RPM torque, lower EGTs on long grades, and better durability compared to the original engine. Tuning often improves drivability, shift strategy, and boost control, especially on tow-focused builds.
