Mopar vs Fleetguard - Which Is Better for RAM Trucks?
If you own a RAM 2500 or 3500 with a 6.7 Cummins engine, you’ve likely asked this question: Mopar vs Fleetguard - which is better for RAM trucks?
Short answer: Both brands produce high-quality filtration products. However, Mopar filters are engineered specifically for RAM factory specifications, while Fleetguard filters are widely trusted in commercial and heavy-duty diesel applications.
In this detailed comparison, we’ll break down oil filters, fuel filters, air filters, compatibility considerations, and long-term engine protection so you can make an informed decision for your truck.
Understanding the Brands: Mopar vs Fleetguard
What Are Mopar Filters?
Mopar filters are OEM (Original Equipment Manufacturer) components for Chrysler, Dodge, Jeep, and RAM vehicles. If you purchase a brand-new RAM truck, it leaves the factory equipped with Mopar filtration systems.
Mopar filters are designed to match:
- Factory oil pressure specifications
- Correct micron filtration ratings
- Exact RAM engine tolerances
- OEM fitment and seal integrity
- Warranty compliance requirements
This includes everything from mopar oil filters to fuel filtration systems and the ccv filter 6.7 cummins.
What Are Fleetguard Filters?
Fleetguard is a filtration brand associated with Cummins (now under Atmus Filtration Technologies). Fleetguard products are widely used in commercial trucks, heavy-duty equipment, and industrial diesel applications.
This often leads to the common question:
Are Fleetguard Filters Made by Cummins?
Fleetguard filters are developed using Cummins filtration technology and are highly regarded in commercial diesel industries. However, not all Fleetguard filters are specifically calibrated for RAM factory specifications.
Fuel Filters: Which Brand Performs Better for RAM?
Fuel filtration is critical for protecting high-pressure injectors in the 6.7 Cummins engine. Common searches include:
- 2013 ram 2500 fuel filter
- 2021 ram 2500 fuel filter
- fuel filter 2024 ram 2500 diesel
Mopar Fuel Filters
Mopar fuel filters are engineered specifically for RAM fuel pressure systems.
- Exact OEM compatibility
- Correct pressure tolerances
- Direct replacement for 6.7 cummins filters
- Warranty-safe solution
For most RAM truck owners, Mopar provides the safest and most straightforward option.
Fleetguard Fuel Filters
Fleetguard fuel filters are well-known in commercial diesel environments. They are often used in fleet trucks and heavy-duty industrial equipment.
However, part numbers must be confirmed using Fleetguard filters lookup tools to ensure compatibility with specific RAM model years.
Verdict: For factory-spec RAM trucks, Mopar typically offers better plug-and-play reliability.
Oil Filters: Who Makes the Best Quality Oil Filters?
Another frequently asked question is:
Who Makes the Best Quality Oil Filters?
Both Mopar and Fleetguard manufacture high-quality oil filters. The key difference lies in calibration.
Mopar Oil Filters
- Calibrated to OEM oil pressure settings
- Correct bypass valve specifications
- Designed for RAM oil flow tolerances
- Optimized for daily driving and towing
Fleetguard Oil Filters
- Built for commercial heavy-duty use
- Strong reputation in industrial applications
- High filtration efficiency claims
However, RAM oil systems are engineered around Mopar pressure flow standards. For factory oil pressure stability, Mopar oil filters provide exact compatibility.
Air Filters: Which Company’s Air Filter Is Best?
Which company's air filter is best?
The answer depends on usage conditions.
- Mopar air filters are optimized for RAM factory intake systems.
- Fleetguard air filters are strong in commercial, dust-heavy environments.
For everyday highway driving and recreational towing, Mopar is typically ideal. For heavy-duty commercial work, Fleetguard may be considered with compatibility verification.
CCV Filtration: An Overlooked Component
The ccv filter 6.7 cummins protects your turbocharger and intake system from oil vapor contamination.
Improper CCV filtration can lead to:
- Oil buildup in intake systems
- Turbo performance issues
- Increased crankcase pressure
- Oil leaks
Mopar CCV filters are designed specifically for RAM emissions systems. Fleetguard does not always provide direct RAM-specific CCV replacements.
What Is the Best Fuel Filter Brand for RAM?
This depends on your priorities.
Choose Mopar If:
- Your truck is under warranty
- You want guaranteed OEM fitment
- You prioritize factory specifications
- You want minimal installation risk
Consider Fleetguard If:
- You operate fleet vehicles
- You prefer heavy-duty commercial filtration
- You verify compatibility carefully
Compatibility: The Most Important Factor
Filtration performance depends on:
- Micron rating
- Flow rate
- Oil pressure tolerance
- Bypass valve calibration
- Seal and gasket design
Even high-quality filters can cause issues if incorrectly matched, including:
- Oil pressure imbalance
- Hard starts
- Injector stress
- Reduced engine performance
This is why direct compatibility matters more than brand name alone.
Side-by-Side Comparison
| Category | Mopar | Fleetguard |
|---|---|---|
| OEM Fitment | Exact Factory Match | Requires Verification |
| Warranty Safe | Yes | Depends |
| Heavy-Duty Commercial Use | Good | Excellent |
| RAM-Specific Engineering | Yes | Not Always |
Final Verdict: Mopar vs Fleetguard — Which Is Better?
For most RAM truck owners, Mopar offers the safest and most direct solution. It aligns with factory engineering, warranty requirements, and OEM pressure specifications.
Fleetguard remains a respected heavy-duty brand. However, compatibility confirmation is essential before installation.
If your goal is long-term engine protection with minimal risk, Mopar is generally the more reliable choice for RAM applications.
