7.3 Powerstroke Stock Clutch Kit w/Flywheel – South Bend 1944-6K
Restore smooth, reliable shifting to your 1999–2003 7.3L Powerstroke with the South Bend Clutch 1944-6K Stock Clutch Kit. This complete single-disc kit is purpose-built as a direct stock replacement for trucks equipped with the ZF6 6-speed manual transmission and includes a high-quality South Bend solid-mass flywheel.
Why the 1944-6K Stands Out
The factory dual-mass flywheel on 7.3 Powerstrokes is known to fail over time, especially on higher-mileage trucks or those that tow. This South Bend kit converts your truck to a solid single-mass flywheel for superior strength and durability while maintaining excellent drivability for stock or near-stock power levels.
South Bend’s premium Kevlar pilot bushing is included — it handles the unique vibration characteristics of the 7.3 diesel far better than the stock nylon bushing and can even serve as a repair bushing if your input shaft shows minor wear.
Key Features
- Full-face organic clutch disc for smooth engagement and quiet operation
- Converts problematic dual-mass flywheel to a durable solid-mass flywheel
- Includes South Bend’s high-quality Kevlar pilot bushing
- Low pedal effort with excellent street manners
- Complete kit — everything needed for installation
- Made in the USA by South Bend Clutch
What’s Included
- South Bend solid-mass flywheel

Fitment
1999–2003 Ford 7.3L Powerstroke with ZF6 6-speed manual transmission (F-250, F-350, F-450, F-550 Super Duty).
Note: Not compatible with early 1999 models equipped with the ZF5 5-speed (use part 1944-5K instead). Always confirm your transmission before ordering.
Technical Specifications
- Stage: Stock / Stage 1 replacement
- Disc Diameter: 13" (330 mm)
- Input Shaft: 1.375" diameter × 10 spline
- Flywheel: Solid single-mass (replaces factory dual-mass)
