Will this work for a 5.9L or 6.7L Cummins swap to a Ford ZF-5?Yes. The F/C 1944-5OFEK is a popular Cummins-to-ZF-5 conversion clutch kit and includes a single-mass flywheel. Verify your adapter plate and input shaft specs before ordering.
Is it compatible with a 1994–1998 7.3L Powerstroke ZF-5?
Yes. It’s commonly used on 7.3L ZF-5 trucks as a single-mass conversion with higher holding capacity compared to the OEM dual-mass setup.
How much power and torque will it hold?
It’s typically rated around 475 HP and 1000 ft-lbs (vehicle dependent). Driving style, gearing, and weight will affect results.
Is the flywheel included?
