South Bend SBC13125-OK clutch kit with upgrade 13 inch flywheel, uses stock 1 1/4" input shaft. Rated 400HP/800TQ. Fits 88-04 5 speed and 6 speed (non H.O.)
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. We have taken the 13" ETH clutch and modified it to accept the 1 1/4" input shaft. By doing this, it enabled us to offer 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 400 horsepower & 800 ft. lbs. of torque. Years 1988-2004 5 speed & 6 speed non-ETH.
