The South Bend 1944-6K is a stock clutch kit for a 1999–2003 7.3 with a ZF6. It is the Stage 1 replacement. The solid flywheel is in the box. The factory dual-mass flywheel comes out. An early-1999 ZF5 uses 1944-5K.

You get a 13-inch organic disc, the pressure plate, the throwout, a Kevlar pilot, the crank bolts, and an alignment tool. The input is the 1.375-inch, 10-spline shaft. The step up is 1944-6OK, at about 375 hp. The hydraulics are HYDX-F67.3.

It fits 1999–2003 F-250 through F-550 trucks with a ZF6.
