Which Mopar Filter Kit Fits Your Ram? A Model-Year Buying Guide
Buying a filter kit for a Ram 6.7L Cummins can become confusing once you start comparing part numbers. Two kits may look similar in a product listing, yet contain different filters or be intended for different model-year applications.
The part number printed on the filter is therefore more useful than simply searching for a “6.7 Cummins filter kit.” For example, Mopar 68157291AA is used across a range of Ram applications, while 68436631AA is associated with later-model fuel and water-separator applications. The right choice depends on the truck, model year and the specific filtration service being carried out.
That distinction matters when selecting 6.7 Cummins filters for a Ram 2500, 3500, 4500 or 5500. A filter kit should be matched to the vehicle rather than selected simply because the product title contains “6.7L Cummins.”
Start With the Ram Model Year
The safest way to find a Mopar filter kit that fits your Ram is to start with the model year and then work through the truck model, engine and applicable filter part numbers.
The 6.7L Cummins has been used across several generations of Ram heavy-duty trucks, and the filtration components used within those applications are not necessarily identical. A part number that appears on multiple model years does not automatically mean that the complete filter kit is unchanged.
This becomes particularly relevant when comparing fuel-filter kits. Mopar currently separates its Dodge Ram 6.7 filters by application, with products covering different model years and combinations of fuel, oil and crankcase filtration.
Working from the vehicle first makes the buying process considerably easier. Once you know the model year and engine, you can compare the exact contents of the available kits instead of trying to determine compatibility from a product photograph or a generic search result.
2013–2018 Ram 6.7L Cummins Filter Kits
For owners of 2013–2018 Ram 2500, 3500, 4500 and 5500 models equipped with the 6.7L Cummins, the filter configuration should be checked against the specific application before ordering.
Mopar 68157291AA is one of the important part numbers associated with these applications, but it should not be treated as the only piece of information needed to select a complete service kit.
Mopar currently lists a 2013–2018 fuel filter kit as well as a combined fuel and oil filter kit. The latter includes 68157291AA, 68197867AB and 05083285AA, showing why it is useful to look at the complete contents of a kit rather than searching for one filter number in isolation.
If the service you are performing only requires the fuel filtration components, a fuel filter kit may be appropriate. If you are carrying out a broader maintenance service that also includes engine oil filtration, a combined fuel and oil kit may be more practical.
The important point is that the kit should correspond to the vehicle's application. Do not assume that a later-model kit will fit simply because your truck also has a 6.7L Cummins.
2019–2024 Ram 6.7L Cummins Filter Kits
The later-model applications require a different approach when comparing filter kits.
Mopar currently lists 2019 - 2024 Ram 2500, 3500, 4500 and 5500 6.7L Cummins fuel-filter kits containing 68157291AA and 68436631AA. It also offers combined fuel and oil kits containing those fuel-filter components together with 5083285AA.
This is a good example of why a complete kit should be evaluated by its application and contents. 68157291AA and 68436631AA are not simply two alternative versions of the same filter. They represent different filtration components used within applicable later-model fuel systems.
If you are comparing those two part numbers specifically, the detailed guide Mopar 68436631AA vs 68157291AA explains how the components differ and why both numbers can appear together in a filter listing.
For a complete service, the correct kit can therefore be more useful than purchasing individual filters without first checking which components your particular Ram requires.
Fuel Filter Kit or Fuel and Oil Filter Kit?
Not every filter service calls for the same combination of parts.
If you are replacing only the fuel filtration components, an application-specific fuel filter kit may be all you need. If the truck is also due for an engine oil service, a combined fuel and oil kit may allow you to source the required filtration components together.
The distinction can be seen in the current catalogue. The 2013–2018 range includes a fuel and oil kit containing 68157291AA, 68197867AB and 05083285AA, while the 2019–2024 range includes a kit containing 68436631AA, 68157291AA and 5083285AA.
Those different combinations are precisely why the model year matters. The phrase “Ram 6.7 Cummins filter kit” describes a broad category, not a single universal product.
For owners who want to compare the available filtration products before choosing a kit, the Dodge Ram 6.7L filter collection provides a useful starting point for checking the available applications.
What About the CCV or Crankcase Filter?
Fuel and oil filtration are not the only maintenance considerations on a 6.7L Cummins.
The crankcase ventilation system uses a separate filter, commonly referred to as a CCV filter or crankcase breather filter. It deals with crankcase gases and separates oil mist within the ventilation system. It should therefore be considered separately from the fuel and engine oil filters.
For applicable 2008–2021 Ram 2500–5500 6.7L Cummins applications, Mopar lists the CV52001 CCV filter as a crankcase ventilation replacement.
If your maintenance requirements include crankcase ventilation service, the Mopar crankcase filter should be checked independently rather than assuming that a fuel or oil filter kit includes it.
This is also why a complete maintenance plan can involve several different filter categories. A fuel filter, oil filter and CCV filter perform different jobs and may have different model-year applications.
How to Choose the Correct Mopar Filter Kit
Once you have identified the vehicle, selecting the appropriate kit becomes much more straightforward.
1. Confirm the model year
Start with the truck's exact model year. This is one of the most important pieces of information when comparing filter kits for the 6.7L Cummins.
2. Confirm the Ram model
Check whether the vehicle is a Ram 2500, 3500, 4500 or 5500. Chassis-cab and pickup applications should not be assumed to be identical without checking the applicable parts information.
3. Confirm the engine
Make sure the truck is equipped with the 6.7L Cummins diesel engine. Searching by “Ram” alone is not enough because different engines use different filtration systems.
4. Check the existing part number
If you are replacing an existing component, inspect the number printed on the filter or use your previous service records. A number such as Mopar 68157291AA provides a much more precise starting point than a generic “Ram fuel filter” search.
5. Decide what service you are performing
Determine whether you need fuel filters only, fuel and oil filters, or additional crankcase filtration. This prevents you from buying a kit that contains components you do not currently need or, more importantly, leaving out a filter that is due for replacement.
Why Buying by Part Number Alone Can Be Misleading
Part numbers are extremely useful, but they should still be considered alongside vehicle fitment.
For example, 68157291AA appears across multiple Ram model years. That does not mean every surrounding component or every complete filter kit is identical across those vehicles.
The same applies when searching online for “Dodge Ram 6.7 filters.” A search can return products covering several generations, different filter positions and different service configurations.
Product descriptions should therefore be checked for the complete application, including model year, vehicle model, engine and the filter components included in the kit.
Photographs should also be treated as secondary information. Two filters can look very similar while carrying different part numbers or serving different positions within a filtration system.
Common Mistakes When Buying a Ram Filter Kit
Choosing by engine size alone. A 6.7L Cummins engine designation does not provide enough information to select every filtration component.
Assuming one kit covers every model year. Earlier and later Ram applications can use different combinations of filter part numbers.
Confusing individual filters with complete kits. A product containing one filter number is not necessarily a complete fuel-filtration service.
Ignoring the kit contents. Always check exactly which part numbers and quantities are included before ordering.
Forgetting about CCV filtration. The crankcase ventilation filter is a separate component and should be considered according to the truck's applicable maintenance requirements.
A Practical Way to Find Your Ram's Filter Kit
The simplest approach is to work through the vehicle in a fixed order:
- Identify the Ram's model year.
- Confirm the vehicle model.
- Confirm the 6.7L Cummins engine.
- Identify the applicable filter part numbers.
- Decide whether you need fuel-only, fuel and oil, or additional filtration components.
- Check the exact contents of the selected kit before ordering.
If you are still unsure, use the vehicle identification number and verify the application through a reliable parts catalogue or manufacturer/dealer source. That is preferable to guessing based on a similar-looking filter or a generic search result.

Frequently Asked Questions
Does 68157291AA fit every 6.7 Cummins Ram?
No. The part number is used across a broad range of applicable Ram 6.7L Cummins vehicles, but the correct complete kit still depends on the model year, vehicle and filtration configuration.
What is 68436631AA?
68436631AA is a fuel/water separator filter kit associated with applicable later-model Ram 6.7L Cummins applications. It can appear alongside 68157291AA in complete fuel-filter kits.
Should I buy a fuel-only kit or a fuel and oil filter kit?
That depends on the service you are performing. If only the fuel filtration is due, a fuel-only kit may be sufficient. If the engine oil service is also due, a combined kit may be more appropriate.
What is the CV52001 CCV filter?
CV52001 is a crankcase ventilation filter application listed for certain 6.7L Cummins Ram vehicles. It is separate from the fuel and oil filters and should be verified against the truck's model year and application.
How do I know which Mopar filter kit fits my Ram?
Start with the model year, Ram model and 6.7L Cummins engine. Then verify the applicable part numbers and check the exact contents of the kit before ordering.
Conclusion
Finding the right filter kit for a Ram 6.7L Cummins is much easier when you start with the vehicle rather than the product.
Model year, Ram model, engine and applicable part numbers all matter. A 2013 - 2018 chrysler may use a different filter combination from a 2019 -2024 chrysler, even though both are powered by the 6.7L Cummins. The same principle applies to CCV filtration and combined fuel-and-oil service kits.
Before placing an order, confirm the truck's application and compare the exact part numbers included in the kit. That simple step helps ensure you are buying the filtration components intended for your Ram rather than relying on a generic “6.7 Cummins filter” search.
