Clutch Conversion Kit for Cummins-powered Ford truck

If you’ve got a Cummins-swapped Ford Super Duty and you’re running a ZF-6 manual transmission, the South Bend Clutch Organic/Feramic Clutch Kit is the kind of upgrade that ties your whole setup together. Built specifically for 2004–2010 Ford F-250 and F-350 trucks running either a 5.9L or 6.7L Cummins engine with the ZF-6 trans, this clutch was made for guys who aren’t just building trucks—they're building purpose-driven machines. What makes this kit stand out is the clutch disc itself. South Bend uses a hybrid material setup—organic on one side, feramic on the other. The organic side gives you smoother engagement when you’re rolling through gears around town or backing up to a trailer. The feramic side steps in when things get serious—holding strong under high torque, resisting heat, and keeping its grip when you’re towing heavy, climbing grades, or laying into the throttle. It’s a smart blend of drivability and durability, which makes it perfect for trucks that work hard but still get driven on the street.

Designed for High-Performance Builds

This is a Stage 3 setup, so it’s built to handle up to 475 horsepower and 1,000 lb-ft of torque—more than enough for most tuned Cummins swaps. It also supports up to 25,000 lbs of towing capacity, making it a great fit for haulers, weekend warriors, or anyone using their truck to tow goosenecks, equipment trailers, or campers on a regular basis. The kit comes complete with the 13-inch clutch disc, pressure plate, and a flywheel—all matched to work together for optimal performance. The flywheel is important here because it ensures proper engagement and helps absorb shock, which reduces wear and helps everything last longer. In simple terms, this clutch kit connects your engine to the transmission and helps transfer all that torque to the wheels without slipping. If your old clutch is starting to give out—or you’re still running stock components on a high-torque swap—this kit brings the reliability and performance you need to put the power down confidently.

Fits: 2004, 2005, 2006, 2007, 2008, 2009, 2010 Ford 6.0L/6.4L Powerstroke with ZF-6 Transmission

Note: This clutch is not recommended for stock Powerstroke engines. It’s made specifically for Cummins swap builds using the ZF-6 manual
