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.
