Thumbnail Filmstrip of 1999-2003 7.3L Powerstroke Organic HD 425hp Clutch Kit w/Flywheel South Bend 1944-6OKHD Images
The South Bend 1944-6OKHD is an organic heavy-duty clutch kit for a 1999–2003 7.3 with a ZF6. It is rated to about 425 hp and 850 to 900 lb-ft, and about 20,000 pounds of towing. The single-mass flywheel is in the box. The factory dual-mass flywheel does not stay.
You get a 13-inch organic disc with a sprung hub, a heavy-duty pressure plate, a cast-iron throwout, a Kevlar pilot, the crank bolts, and an alignment tool. Organic takes off smoother than ceramic. Break it in for about 500 miles of stop-and-go before a heavy tow. The hydraulics are a separate kit, Hydx-F67.3.
It fits 1999–2003 F-250 through F-550 trucks with a ZF6.
