South Bend SDD3250-G-ORG Organic Street Dual Disc Clutch Kit 5.9L | 6.7L Cummins • 2005.5–2018 Ram 2500/3500 G56 6-Speed

Smooth street manners with serious heavy-towing capability.

The South Bend SDD3250-G-ORG is a full-organic dual-disc clutch engineered specifically for G56-equipped 5.9L and 6.7L Cummins trucks that see daily driving, heavy towing, and moderate performance upgrades. Unlike more aggressive hybrid or ceramic clutches, this full-organic design delivers progressive, chatter-free engagement that feels stock-smooth while providing the torque-holding power needed for real-world work and towing.

Key Benefits

• Full organic friction material on both discs provides the smoothest engagement and easiest modulation — ideal for daily driving, stop-and-go traffic, and backing trailers.
• Dual-disc design dramatically increases torque capacity and improves heat dissipation compared to single-disc clutches.
• One-piece flywheel conversion replaces the factory dual-mass flywheel with a stronger, more reliable steel flywheel.
• Excellent choice for modified trucks or heavy tow rigs that still need street-friendly drivability.
• Rated for up to 550 HP and 1,100–1,200 ft-lbs of torque (application dependent).
• Capable of handling 30,000+ lb towing loads when properly matched to gearing and engine management.

Vehicle Fitment

2005.5 – 2018 Dodge Ram 2500 / 3500 (select 4500 models) with 5.9L or 6.7L Cummins and G56 6-speed manual transmission.

What’s Included

• Dual full-organic clutch discs + floater plate
• Performance pressure plate
• One-piece flywheel
• Throw-out bearing
• Pilot bushing
• Alignment tool
• Mounting hardware

Why Choose the SDD3250-G-ORG?

This clutch gives Cummins owners the best of both worlds: the smooth, low-chatter engagement of an organic clutch with the holding power of a dual-disc setup. It’s the go-to choice for daily-driven, heavy-towing, or moderately modified G56 trucks that don’t need race-level aggression.
