The South Bend Clutch G56-OFEK is a Stage 2 diesel clutch upgrade designed for Cummins trucks equipped with the G56 6-speed transmission. Built with a 13-inch organic/feramic (OFE-K) friction design, this clutch delivers increased torque capacity while maintaining smooth, street-friendly engagement.

The organic/feramic combination gives you the best of both worlds—smooth engagement from the organic side and added holding strength and heat resistance from the feramic material. This makes it ideal for trucks that tow, work, or run moderate power upgrades without sacrificing drivability.

Rated around 475 HP and 1000 lb-ft of torque with up to 25,000 lb towing capacity, this clutch is built to handle real-world load and heat where stock setups fall short.

This is a complete kit, designed as a matched system for reliability and performance.
