South Bend Clutch Performance Kit Descriptions

The South Bend Street Dual Disc Clutch is the perfect option for the truck that does it all. From daily-driven street performance to towing, the 13" diaphragm style 3250lb. pressure plate offers maximum holding power with easy pedal effort. An industry first! South Bend has developed an organic friction in a button form allowing for a dual friction, dual disc clutch. The organic lining will be facing the pressure place and flywheel for smooth engagement yet still offers superior holding power. All the clutch components in this assembly are made of steel. The center plate is lugged to fit the flywheel. This complete clutch has no special requirements for install. It is a direct replacement of the OEM clutch.

South Bend Clutch Dyna Max street dual disc clutch kits are offered for a range of applications and setups. These clutch kits are made using high performance materials and include everything you need for your clutch installation. Many kits include KEVLAR pilot bushings. When it comes to street performance, you can count on South Bend for top-quality components.

  • So its time to replace my clutch (2010 Dodge 2500 6.7 cummins/G56). I upgraded from the stock clutch already with a Luk DD clutch (NAPA) so the hydraulics have been upgraded from stock. My question is should I upgrade the hydraulics again with the new South Bend setup?

    It would be recommended, but not required.

  • will this kit fit on a 2018 Ram 2500?

  • can i purchase a pressure plate separately from this kit? i don't need a clutch at this time. my throw out bearing went out and damaged the fingers on the pressure plate. i will need a new pressure plate, throw out bearing, clutch fork, input shaft sleeve.. let me know. Thanks.

    Please contact Southbend Clutch 800-988-4345.

  • 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 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.
