Pre-Interview Survey conducted by East Coast Diesel.

With an aim to provide first hand and accurate information on Dual Disc South Bend clutches for Ford, Chevy and Dodge, the East Coast Diesel team initially conducted a survey and interviewed 100’s of customers to find out how happy they were after switching to the Dual Disc South Bend Clutches for their vehicles and if they had any questions which they needed answers for.

After the survey, a final list of all the FAQ’ was shortlisted and Peter Pyfer was interviewed for answers.

With years of expertise dealing with Double Disc South Bend Clutches, the ECD Diesel team augmented Peter’s answers with additional information based on their experiences.

FAQ’s answered by Southbend clutch CEO, Peter Pyfer and East Coast Diesel’s CEO – Delton Sensenig.
1. How much noise is the South Bend dual disc clutch going to make once installed in my truck.?
Peter Pyfer, CEO, South Bend Clutch

Peter Pyfer (South Bend Clutch):

Yes, it makes a little amount of noise or rattle, whatever you may call it. It depends on the type of vehicle, which transmission, how the truck is performing, and quality of transmission.

Delton Sensenig, CEO, East Coast Diesel.

Delton Sensenig (East Coast Diesel):

Over the Years, the Dual Disc clutch from South Bend has been known to be a noisy clutch setup. We at ECD Diesel have seen firsthand how the Street Dual disc clutch has become less noisy and lot quieter. We have found that some trucks have less noise/rattle than others. Very often, the noise that people associate with the Dual Disc Clutch can also be gear noise in the transmission which can make a racket. This is often different when people change a clutch due to the fact that with a heaver clutch kit, if there is wear in the transmission, it can cause a noise/rattle that was not there before and is often labeled as clutch noise or rattle or racket caused by the Dual Disc Clutch.

2. What has South Bend Clutch done over the years to reduce the noise/rattle and build a quieter dual disc clutch?
Peter Pyfer, CEO, South Bend Clutch

Peter Pyfer (South Bend Clutch)

Better designs for the dampened section of the clutch disc and anti-rattle center plates have reduced the noise substantially.

Delton Sensenig, CEO, East Coast Diesel.

Delton Sensenig (East Coast Diesel)

We have seen SBC use a much heavier clutch hub, This has resulted in better dampening of the engine vibration through the clutch assembly and in turn created a much quieter clutch assembly. We have also noticed a reduction in noise/rattle with the implementation of pinned floater plates which keeps the floater from moving around when the double disc clutch is disengaged.

3. Since the Introduction of the SBC street dual disc clutch, has there been any changes to them?
Peter Pyfer, CEO, South Bend Clutch

Peter Pyfer (South Bend Clutch):

Over time, the weak points of the earlier designs have been addressed.

4. What are the changes that have been made?
Peter Pyfer, CEO, South Bend Clutch

Peter Pyfer (South Bend Clutch):

Using multi-friction materials, organic and ceramic, for better engagement. Silencing the notorious center plate rattle. Easier effort pressure plate. Better dampened clutch discs.

Delton Sensenig, CEO, East Coast Diesel.

Delton Sensenig (East Coast Diesel):

Since the introduction of the Multi Friction materials, the dual disc clutch has become very smooth to engage. Most of the early style street dual disc’s used a 12 button ceramic friction. The ceramic friction was more of an on or off clutch, meaning you were not able to slid the peddle out without it getting to the point where it was either engaged or disengaged. This would result in a rough start while on a hill trying to start out or when backing a trailer around. Since the introduction of the multi friction, all these problems have gone away. These multi friction dual disc clutches will engage like a stock clutch and yet hold about 700rwhp. What more could you ask for.

5. How did those changes better the dual disc clutch?
Peter Pyfer, CEO, South Bend Clutch

Peter Pyfer (South Bend Clutch):

Reduced noise, ease of effort on clutch pedal with smoother engagement.

6. Does the SBC street dual disc have a hard clutch pedal?
Peter Pyfer, CEO, South Bend Clutch

Peter Pyfer (South Bend Clutch):

No.

Delton Sensenig, CEO, East Coast Diesel.

Delton Sensenig (East Coast Diesel):

We have noticed that the clutch pedal on the South bend street dual disc clutch is often much lighter than the stock clutch pedal. It is often the case that when a customer comes to pick up their truck, after a South Bend Street Dual Disc install, that they question the fact that we actually installed a Performance or Heavy Duty style clutch due to the fact that the pedal is lighter than the stock clutch.

7. What types of friction compounds are used in a street dual disc clutch?
Peter Pyfer, CEO, South Bend Clutch

Peter Pyfer (South Bend Clutch):

Multi-friction organic and ceramic.

Delton Sensenig, CEO, East Coast Diesel.

Delton Sensenig (East Coast Diesel):

The South Bend Street Dual Disc has a Performance Organic friction on the Pressure Plate side and also on the Flywheel side. Ceramic Friction on the floater plate side is used to hold the horse power that the diesel trucks are so easily able to produce.

8. Why are these particular compounds used?
Peter Pyfer, CEO, South Bend Clutch

Peter Pyfer (South Bend Clutch):

Organic for the smooth engagement, and ceramic for additional holding power.

Delton Sensenig, CEO, East Coast Diesel.

Delton Sensenig (East Coast Diesel): Organic:

This is a material similar to the factory style material only specifically designed for SBC and is often times referred to as a “Performance Organic” The SBC Performance Organic also has some metallic material in the compound as well. The Performance Organic material will allow for a smooth engagement of the clutch as well as a little better holding power the the stock style organic compound. This friction is referenced in the SBC part numbers list with an “O” in the Suffix.

Feramic:

This material is a Fiber / Ceramic material. Feramic has the ability to hold good horsepower but does not like heat. This type of clutch material needs to be used in an application were you have a good amount of horsepower but do not use the truck in a heavy towing application where you are riding the clutch pedal. This will cause excessive heat on the clutch disc and result in the material becoming very sticky to the point where it could weld itself to the flywheel resulting in you not being able to disengage the clutch. This type of friction is referenced in the SBC part number as “F” in the suffix

Ceramic:

This material is designed to be a very aggressive friction material. Ceramic is a compound that is designed to take a good amount of heat but also has an engagement more like a on / off switch where you find yourself either being engaged or disengaged. Often time this material can be abrasive to the surface of the flywheel as well. In order to use this type of friction material you need to have good amount of horsepower to keep this material from “Glazing”. Once the Ceramic compound is glazed due to not aggressive enough driving or lack of horsepower, it will often times not hold very well and cause a slipping issue. This type of friction is referenced in the SBC part number as “C” in the suffix.

Kevlar:

This material is a high-durability material more resistant to hard use. Kevlar has a Higher temp range in general, but can be ruined from overheating and will not return to original characteristics if over heated. If over heated the Kevlar material will be ruined and go to nothing. This type of friction is referenced in the SBC part number as “TZ” in the suffix.

Sintered Iron:

This material is a extremely high temperature material. The Sintered Iron is used in the competition application. This is often the material use in clutches referenced as slipper clutches. Sintered Iron must be used on special flywheels and must only be used in extremely high horsepower applications.

9. How does the SBC street dual disc clutch differ from a competition dual disc clutch?
Peter Pyfer, CEO, South Bend Clutch

Peter Pyfer (South Bend Clutch):

Competition clutches are designed for just that. They will have more noise, rougher engagement and harder pedal effort.

Delton Sensenig, CEO, East Coast Diesel.

Delton Sensenig (East Coast Diesel):

The Comp style clutches will have a much heavier pedal due to a heavier pressure plate. A comp style clutch is designed to be abused and also take a lot of heat hence the reason that they are not a very smooth engagement and have a heavy pedal. The comp style clutch also has to have special certifications that will help ensure that they don’t explode due to heat in competition style use.

a. How do I choose the right dual disc clutch for my truck?
Peter Pyfer, CEO, South Bend Clutch

Peter Pyfer (South Bend Clutch):

If you are going to do any drag racing, sled pulling or horse playing, the street dual disc is not for you.

10. What type of truck was the street dual disc clutch originally designed for?
Peter Pyfer, CEO, South Bend Clutch

Peter Pyfer (South Bend Clutch):

Higher horse power, heavy hauling/towing.

Delton Sensenig, CEO, East Coast Diesel.

Delton Sensenig (East Coast Diesel):

We have found the best use of the Street Dual Disc is for the customer who has a truck that is used for heavy towing and has a couple of power adders such as chip or programmer, larger Injectors and or bigger turbochargers. When adding these types of power upgrades to your diesel truck you will produce more low rpm torque which requires a heaver clutch assembly.

11. How does a street dual disc clutch effect the longevity of my transmission?
Peter Pyfer, CEO, South Bend Clutch

Peter Pyfer (South Bend Clutch):

If you keep the rpms up while driving and shift properly the transmission will not be harmed. Towing in overdrive, while under load, will.

Delton Sensenig, CEO, East Coast Diesel.

Delton Sensenig (East Coast Diesel):

The SBC street dual disc clutch is designed for street use. It is designed to not damage your transmission from normal day to day use. This is a heavy duty clutch that is designed NOT to slip in the event that you lug your motor into the low rpm’s where the most amount of torque is created. In a case where you have a stock style clutch and you lug in the low rpm’s, you will slip the clutch before it will create any damage, but in the dual disc it will not slip, meaning that if you lug the rpm’s down you do run the risk of putting extra unneeded stress on your driveline.

12. What is the difficulty of installing this Dual Disc Clutch; Can I do it myself?
Peter Pyfer, CEO, South Bend Clutch

Peter Pyfer (South Bend Clutch):

If you’re mechanically inclined there should be no problem installing the street dual disc. However, it is recommended to have a licensed mechanic do the work.

Delton Sensenig, CEO, East Coast Diesel.

Delton Sensenig (East Coast Diesel):

This is a question that is often asked when customers order a Dual Disc Clutch. The answer is that there is no difference to

installing a dual disc clutch as there is to a single disc clutch, simply that there is an extra disc. The dual disc bolts up

exactly the same. So to answer this question, if you are able to install a clutch then you will have no problem installing the

dual disc clutch. The South Bend Clutch kits come complete with everything you need to install it.

Delton Sensenig, CEO, East Coast Diesel.
