Dual Disc for 550-650 hp, 1200 ft. lbs. torque - For use with stock input shaft

South Bend Clutch heard the call for the organic dual disc clutch but wanted to offer the best in both durability and drive ability. How do they achieve that? In our 50 years of experience we knew that running an all organic dual disc would have it's problems. The intermediate (center) plate is approximately 1/2" thick whereas the pressure plate and flywheel castings are three times that. Running two friction surfaces on one thin casting will increase the temperature to that casting. Organic burn point is approximately 550 degrees whereas ceramic can reach 1,100 degrees. The immediate engagement points when the clutch is released for takeoff are the outside points of a dual disc clutch, pressure plate and flywheel. Being that there is only one friction surface running to these two points, and the fact that the pressure plate and flywheel castings are much thicker than the center plate, the temperatures cannot reach that of the center plate. This is why organic will work to the pressure plate and flywheel and not to the center plate.

South Bend Clutch feels they have reached a milestone in the clutch industry and hope that you will enjoy our hard work at being the industry leader in research and development of clutches for the diesel market.

  • 13" diaphragm style 3250 lb. Pressure plate offers maximum holding power with easy pedal effort.
  • The ceramic buttons will be facing the center plate. This will increase the holding power as well as increase the temperature capabilities to the intermediate plate.
  • Clutch discs are a dampened free travel design similar to the semi clutch to help reduce gear roll over.
  • One of a kind dampened center plate was designed to eliminate rattle when clutch is released.
  • First in the clutch industry! We have developed organic friction in a button form allowing us to create a multi friction, dual disc clutch. The organic will be facing the pressure plate and flywheel for smooth engagement yet still offers superior holding power.

  • Do I use a stock throw out bearing? Or is there a replacement?

    Alex | 8/12/2019

    This kit comes with a new throwout bearing.

  • Do i need the pump that comes with the new clutch or can i use my old pump from the truck?

    Alex | 2/20/2020

    If you mean the stock hydraulics, South Bend recommends going with the upgrade hydraulics.

  • Why Might My Clutch Slip If I Try To Accelerate In Overdrive?

    Eric Schumann | 5/16/2019

    Too much torque at too low an RPM. I go back to the automatic. If you were driving down the road in automatic overdrive, with the cruise control on, and approached a hill, the system (in order to keep a constant speed) would need to accelerate. The transmission would automatically downshift in order to do so. By keeping the RPM up while accelerating, it is preserving its life. There is a misconception about fuel consumption. People believe that the lower the RPM, the better the mileage, when actually, the opposite is true. All that black smoke you get when you step on it in overdrive is unburned (and therefore wasted) fuel. Keep the RPM up by downshifting into the right gear, and your truck will run much better.

  • Is It Wrong To Tow In Overdrive?

    Eric Schumann | 5/16/2019

    This is a very good question, because most people do just that. The trouble is, it is too hard, with all the variations in terrain, to keep a constant speed. Therefore, you end up accelerating too much in that high gear. Many trucks, with automatic transmissions, set up for towing, will include a button for "tow mode" which locks the transmission out of overdrive. The main reason for that is, the transmission would be constantly downshifting. The best answer is to say; watch your RPM, if it starts to drop too low, rather than stepping down on it in 6th, drop to 5th ...and maybe stay there.

  • Can I Sled-Pull With My Street Dual Disc Clutch?

    Eric Schumann | 5/16/2019

    The simple answer to that question is...no. The SDD was not designed for that purpose. That being said; I know people do it anyway. Some get away with it, and drive home (with both their feet), and some do not. The risk is that the amount of heat produced when you launch with a sled behind you, can fracture (and fragment) the cast iron plates in the clutch. Competition clutches are made out of steel for that very reason. Safety is a factor that should be considered above all.
