Application: 2005-2018 Dodge Ram Cummins Diesel 6 Speed G56
Available in four different horsepower ratings. The 425hp rated clutch uses an organic friction material. This clutch is good for towing less than 10,000 lbs. and modest performance upgrades. The 475hp rated clutch uses an organic friction material on one side and a feramic friction material on the other. This combination is what makes for a higher horsepower rating. Both of these single disc South Bend clutch kits are great for daily driving & moderate towing. The street dual disc clutches are rated at 550hp & 650hp+ each of these have a towing capacity of 30k lbs. The factory dual mass flywheel which is prone to failure is eliminated with this clutch kit and a new upgraded solid flywheel is included. Upgraded, larger diameter clutch hydraulics with a braided stainless line are also included with this kit. Clutch engagement will be smooth and clutch pedal effort will remain the same as the stock clutch. This South Bend clutch kit includes everything needed for a complete installation. Solid flywheel, organic clutch disc or organic/feramic clutch disc (depending on selection) pressure plate, crank bolts, pilot bearing, throwout bearing & alignment tool. South Bend is Made in the USA and the best clutch in the diesel industry. If your in need of a replacement clutch for your G56; seriously consider installing a South Bend clutch.
What clutch should I get?
The G56 was installed behind the Cummins 5.9 and 6.7L engines. The 5.9 made approx. 325 horsepower at the crank. The 6.7 makes approx. 350 horsepower. Southbend rates there clutches based on rear wheel horsepower.
If you have a 5.9L Cummins with a G56 you can add an additional 100hp. The 425hp rated clutch will still hold that additional increase in power due to drivetrain loss from the engine to the rear wheels.
