The Pedal pressures on these South Bend clutches are very close to a stock. (Original Equipment Manufacturer Standards) This is true for all 650 Horsepower or less street clutches. These clutches wont slip, chatter, wear the flywheel, burn up pilot bearings or pop out friction disc springs. South bend is the only clutch we sell because you won't find a better made Diesel Performance clutch. Made In America!
