This is the heavy duty design of the South Bend Clutch 13" clutch kit with a 3" wide premium Organic lining. Perfect for moderate tuning and heavy towing while maintaining smooth engagement.
This Dyna Max kit features an organic lining on a marcelled fin. The pressure plate is modified for higher plate load and smoothness of engagement. This clutch was designed to cure premature disk failure due to high horse power and heavy hauling in the 5 speed and early 6 speed non-ETH 12 1/4" clutches. South Bend Clutch has taken the 13" ETH clutch and modified it to accept the 1 1/4" input shaft. By doing this, it enabled a disk center that is 2-3 times larger and stronger then can be provided in the 12 1/4" clutch kits. This kit comes with a flywheel, re-drilled and refaced to accept the larger clutch and is rated to handle up to 425 horsepower & 900 ft. lbs. of torque. Years 1988-2004 5 speed & 6 speed non-ETH.
These are great stock replacement clutches for trucks with small power improvements and hauling loads within the manufactures gross vehicle weight rating or slightly above.
