Most people thought of a Dodge Ram when they hear the brand Cummins. It is not surprising at all since it has become quite popular when they first came out, and the name stuck. However, Cummins offers four categories of automotive engines, such as Pickup, Light Commercial class, Medium-Duty class and as well as the Heavy-Duty class.
Cummins has been credited in being able to save the Dodge trucks from extinction in the 1980s by supplying Chrysler with their legendary diesel engines. If you are going to look at it now by today’s standards, it is archaic, but back then, it was considered very much advanced as some even called or described it as light years ahead of its automotive rivals.

Buyer’s Guide: Should You Replace Aftermarket Clutch For Your Dodge Ram Cummins Engines
Most auto shop mechanics and technicians would agree that there are basically three common reasons why there is a need to replace the stock clutch for your Dodge Ram Cummins engines.
The first one is because the OEM clutch is totally worn out. The next one is the additional power performance for the Dodge Ram, and the third one is the need for more towing power without the slippage problem.
The Dodge Ram incorporated the Dual Mass Flywheel (DMF) clutch from 2005 up to 2015. This was done to minimize the regular vibration on the trucks and offer a car more-like vibe to the whole stick shift system.
However, some issues came about from those trucks that were upgraded to the Dual Mass Flywheel clutch. Modifications from the original equipment used such as increasing torque capacity can wear out the clutch since it was not originally designed for the upgraded torque rating. Most RAM truck owners shared the same sentiment, and the common feedback was that after just 40K miles, the clutch just easily wore out.
There is already a solution to this issue, which is quite simple and easy to do. Cummins produced the Solid Flywheel Conversion Kit precisely to deal with this problem. Using this conversion kit will provide additional torque rating, but it has a downside. The dual flywheel has to be converted to just a single one and that will bring back the vibrations that can be felt through the transmission.
Understanding Different Cummins Engines
The most popular engines are the 6.7L Cummins and the 5.9L , but each of these two has more types of engines under it. To discuss the best clutches for these engines, let us first briefly look into the different Cummins engines.
The 12-Valve 2nd Gen Cummins was a great improvement from the 1st Gen with new injectors, better turbocharger, and larger intercooler. Cummins even up the ante by making enhancements on the 24-Valve versions while retaining the same body style. It used a rotary electric VP44 fuel injection pump along with a 235 horsepower and 460lb-ft of torque capability.
Upgrading the Cummins Clutch
“Should I upgrade my Cummins Clutch?” is a common question from owners who encountered the following scenarios:
- When the increased horsepower of your Cummins, Duramax, and Powerstroke went beyond what your current clutch can handle.
- You were having difficulty in towing heavy loads, which were beyond the weight level that your current clutch can handle.
- The current clutch of your truck has been worn out and needs replacement.
While vehicle owners share common reasons for thinking of getting an upgrade, not all of them need the same clutch upgrade. Some upgrades are not suitable for all customers. It is wise to get the appropriate clutch grade that would match or be compatible with your diesel engine truck instead of getting the most popular one.
Key Rules in Choosing the Replacement Clutch
- The estimated horsepower (HP) of your vehicle should match the HP rating of the clutch or slightly exceed it.
- Choose the SFI approved multi-disc clutch if you are going to use the vehicle for sled-pulling competitions.
- If your truck regularly tows around 15,000 pounds or more and in excess of about 450 rear-wheel horsepower, the street double disc clutch is best suited for your vehicle.
- A single disc clutch is not recommended for extreme towing or much higher horsepower.
- Do not enter competitions with the street dual disc as they are not designed for it.
- All competition multi-disc clutches should have a certification from the SFI.
- Avoid using competition clutches for towing in the street as they are not user-friendly and extremely tough to use for towing.
- A quality aftermarket clutch, assuming it will be properly driven, is expected to outlast the stock clutch by twice or thrice its normal use.
It is important to remember that things will feel differently when your vehicle has been modified above the limitations that it was designed for. A performance clutch becomes necessary because of these modifications. The appropriate clutch will help lessen the effects of these alterations.
Each clutch is designed with limitations and those with higher or even extreme horsepower are not the easiest to drive. Before making the upgrade, check the limitations of your truck as well as the driving skills to get the most suitable clutch for it.
Before doing the clutch upgrade, be reminded that no matter how high the horsepower, the rating, or how reputable the maker is, no clutch can be considered unbreakable. Use it properly and reasonably so it will last longer.
Essential Factors to Consider When Choosing Dodge Ram Cummins Replacement Clutch
The market is awash with different models and brands of clutches, and this fact makes the selecting process for an ideal clutch replacement challenging. Nevertheless, if you know the following factors to consider when buying a clutch replacement for Dodge Cummins, you will be a step closer to zeroing in on the best clutch for your needs:
When searching for a clutch replacement for your Dodge Cummins, you should first look at your option’s compatibility. Ask yourself if the clutch is compatible with the model you are using. Compatibility includes compatibility in size, number of discs, as well as the desired model’s transmission. You should also take into consideration the vehicle’s power output. With this in mind, you need to select a clutch designed for your Dodge Cummins carefully. Nevertheless, many clutches are designed for a wide range of vehicle types. Yet, you must ensure that it complements the Dodge Cummins well in all aspects.
Different manufacturers make use of various materials when manufacturing their clutch products, and if you are not wary of what you are choosing, you may not buy something durable and friendly to the environment. Since friction happens during the clutch engagement period, it will help if you select a clutch made of materials that can withstand constant friction.
Materials for making a clutch can be organic, ceramic, and many other materials. Organic materials are mostly used for vehicles that you use every day. But for racing cars, the material often used is ceramic. Other materials used for clutch manufacturing include cotton fabrics, steel, aluminum, vegetable fibers, polymers, asbestos, and fiberglass.
Activities You Engage In
If you frequently use your vehicle for your daily activities, you will need a specific clutch for such a purpose. You will also need a different clutch if you are desirous of additional speed.
If you use your vehicle for dragging heavy loads, you will also necessitate a stronger clutch. With a more robust clutch, you will have more torque and horsepower. Hence, it will help if you carefully consider the activities for which you use your vehicle to make an intelligent purchase.
The flywheel is a crucial component of the clutch that stores rotational energy in the system. The flywheels are also made of various materials. Steel flywheels are more durable and offer a more enhanced and more fluid driving experience. Moreover, it is better than aluminum flywheels.
The heart or workhorse of the clutch is the pressure plate. It provides the needed clamping force for the flywheel and disc. The ideal thing for a Dodge Cummins is a diaphragm pressure plate because it allows for a better driving experience while improving the durability of the vehicle.
Making an upgrade to the stock clutch makes a lot of sense, but you should always know your options before making a final decision. Only consider the options that are suitable for your engine. That being said, you should upgrade and enjoy the power of your Dodge Cummins again.
