7.3 OBS Powerstroke Street Dual Disc Clutch – 650hp | South Bend SFDD3250-5
The South Bend SFDD3250-5 Street Dual Disc Clutch is the ideal upgrade for 1994–1997 Ford 7.3L Powerstroke OBS trucks equipped with the ZF5 5-speed manual transmission. Rated for up to 650 horsepower and 1,300 ft-lbs of torque, this Stage 4 dual-disc clutch delivers serious holding power for modified trucks while remaining comfortable and streetable for daily driving and heavy towing.
Why Choose the South Bend SFDD3250-5?
Stock clutches in tuned or heavily loaded 7.3 Powerstrokes quickly become a weak link. The SFDD3250-5 solves that problem with a true dual-disc design that dramatically increases torque capacity without the grabby, heavy-pedal feel of many single-disc performance clutches.
South Bend’s hybrid friction material (half organic / half ceramic with 6 ceramic buttons per side) gives you the best of both worlds:
- Smooth, positive engagement for everyday driving and towing
- Excellent heat resistance and durability under high horsepower and load
A specially engineered dampened center plate virtually eliminates the annoying rattle common in many performance clutches, while the diaphragm-style 3,250 lb pressure plate keeps pedal effort light and manageable.
Key Features & Benefits
- Rated for 650 HP / 1,300 ft-lbs torque capacity
- Half-organic / half-ceramic friction material for smooth street manners + strong holding power
- Dampened center plate eliminates clutch rattle for quiet operation
- Light pedal pressure — comfortable for daily driving and traffic
- Excellent for trucks regularly towing 15,000–30,000+ lbs
- Complete kit includes everything needed for installation
- Not intended for competition or sled pulling use (street/tow focused)
What’s Included
- Ductile iron flywheel
- Diaphragm-style pressure plate (light pedal effort)
- Dual clutch discs with dampened center plate
- Floater plate
- Throwout bearing
- Pilot bearing
- Crank bolts
- Alignment tool
Fitment
- 1994–1997 Ford F-250 / F-350 7.3L Powerstroke (OBS)
- ZF5 5-speed manual transmission
Break-in procedure is critical: Drive 500 miles of normal stop-and-go driving before towing heavy loads. This allows the clutch to properly seat and ensures maximum life and performance.
