The South Bend Clutch 13125-OFEK is a proven OFE-K (Organic/Feramic) clutch upgrade built for diesel trucks that need more holding power than stock without sacrificing driveability.

This setup uses a combination of organic and feramic friction materials to deliver strong torque capacity with smooth engagement. It’s ideal for trucks that tow, work, or run mild performance upgrades but still need to be easy to drive on the street.

Designed for a wide range of Cummins applications, this clutch kit fits 1988–1993 Dodge Getrag, 1994–2003 5.9L NV4500, and 1999–2000.5 NV5600 (235hp) trucks—making it a solid upgrade for both early and late second-gen setups.
