SOUTH BEND G56-OFER SINGLE DISC CLUTCH – 2005.5–2018 RAM 5.9L/6.7L CUMMINS (G56 6-SPEED)

Street/Tow holding power with daily-drive manners. The South Bend G56-OFER is an Organic/Feramic single-disc upgrade for G56-equipped Cummins trucks. It’s rated around 475 HP and 1,000 ft-lbs (vehicle dependent) with smooth modulation—ideal for tuned daily drivers and tow rigs that don’t need a dual disc.

FAQ

No. OFER is a “Rep Kit” (replacement) that reuses an existing compatible single-mass flywheel. If you’re on the OE dual-mass flywheel, choose G56-OFEK which includes a single-mass flywheel.

Approximately 475 HP / 1,000 ft-lbs in a well-sorted truck. Aggressive towing, gearing, and tire weight can affect holding capacity.

Yes. The Organic/Feramic mix is designed for street/tow use with smooth take-off and solid bite under load.

No. The OFER kit does not work with the OEM dual-mass flywheel. Use G56-OFEK if you need a flywheel.

Not always, but higher-clamp clutches benefit from fresh/HD hydraulics. We recommend inspecting or upgrading to HYDX.750.
