South Bend Clutch Performance Kit Descriptions



This Dyna Max kit features a performance organic lining on a carcelled fin. The pressure plate is modified for higher plate load and smoothness of engagement. This clutch was designed to cure premature disc failure due to high horse power and heavy hauling in the 5 speed and early 6 speed non-ETH 12 1/4 clutches. South Bend has taken the 13 ETH Clutch and modified it to accept the 1 1/4 input shaft. By doing this, it enabled them to offer a disc center that is 2-3 times larger and stronger then can be provided in the 12 1/4 clutch kits. This kit comes with a flywheel, re-drilled and refaced to accept the larger clutch and is rated to handle up to 375 horsepower & 800 ft. lbs. of torque. Years 1988-2005 5speed & 6 speed non-ETH.

South Bend Clutch utilizes Cryogenic Processing to strengthen their clutch kits. Deep cryogenic treating is a one-time process that permanently and dramatically improves the performance and useful life of metals in these clutch kits.

After cryogenically treating your disc springs, clutch plate and flywheel, the material will wear less and the plate load will hold up over time. The bottom line is that YOUR CLUTCH WILL LAST LONGER!

South Bend high performance clutches are noted for smooth engagement and low pedal effort. ConO clutches feature organic facings with very smooth engagement. ConOFE clutches have an organic facing on one side and a feramic facing on the other. They have a near stock clutch engagement with very high torque ratings. ConFE clutches have full feramic facings on the disc. FE clutches are a little abrupt on engagement, but still much smoother than competitive ceramic clutches.


Key Benefits:
  • Less voids or imperfections in the metallic grain structure
  • Significantly less micro cracks
  • Significantly less warping caused by heat
  • Better friction coefficient
  • Increased microstructure surface area
  • Increased wear resistance
  • Increase wear consistency
  • Relief of internal residual stress
  • Springs will maintain compression longer

  • I have a 1 and 3/8 input shaft what clutch can I use

    Sean Murphy | 3/12/2024

    With the larger input shaft you will require a clutch for the nv5600 and a starter spacer. If you do not have.

  • Doing a replacement clutch on my 1999 Dodge 2500 4x4 Cummins diesel truck. We tow our travel trailer which weighs 9000 lb. I’d say the truck hauls our trailer 20% of its time. I’ve had slightly bigger injectors put in, exhaust upgraded to 4”. That’s about all the power upgrade. What clutch would you suggest for my use. Also are you authorized sellers for South Bend products for warranty purposes? Thank you, Dave

  • 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.
