South Bend SFDD3250-6 Street Dual Disc Clutch Kit | 650 HP / 1,300 ft-lbs | 1999-2003 7.3L Powerstroke ZF6
Take your 7.3 Powerstroke to the next level with the South Bend SFDD3250-6 Street Dual Disc Clutch. This premium Stage 4 dampened dual disc clutch is engineered for serious street performance and heavy towing while delivering excellent drivability and a surprisingly light pedal feel.
Rated for up to 650 horsepower and 1,300 ft-lbs of torque, the SFDD3250-6 is the perfect upgrade for modified 7.3L trucks or those regularly towing heavy loads (rated for 30,000+ lbs towing capacity). The hybrid half-organic / half-ceramic friction material provides smooth, positive engagement without the harsh chatter common in aggressive clutches.

- Quiet Operation — Dampened center plate (floater) virtually eliminates rattle and gear noise for a refined driving experience
- Smooth Engagement — Hybrid organic/ceramic disc material offers progressive bite and minimal driveline shock
- Complete Bolt-In Kit — Includes everything needed for a professional installation
What’s Included
- Ductile iron flywheel
- Dual disc clutch assembly (half organic / half ceramic)
- Diaphragm pressure plate

Important Notes
