There isn’t one universal oil filter part number for the Ram 2500 with Cummins—the correct filter depends on the engine and model year. The two main engines used in these trucks are the 5.9-liter Cummins (2003–2007) and the 6.7-liter Cummins (2007–present).
Engine generations in the Ram 2500 Cummins
These are the two diesel engines that have powered the Ram 2500 with Cummins over the years. The oil filter part number varies by both engine size and production year, so identifying your exact engine is essential before purchasing a filter.
5.9L Cummins (2003–2007)
The 5.9L Cummins era uses an oil filter size and mounting that differs from the later 6.7L. When replacing, look for the OEM filter designed for the 5.9L Cummins and consider reliable aftermarket cross-references if you prefer a non-OEM brand. Verify compatibility for your specific VIN and production date, as some parts may be shared within the family but are not always interchangeable across all years.
6.7L Cummins (2007–present)
The current 6.7L Cummins uses a distinct filter cartridge and mounting from the 5.9L. OEM filters for this engine are different, and many aftermarket options provide cross-references. Ensure the filter you choose is listed specifically for the 6.7L and your model year to ensure a proper seal and fit.
Because filter part numbers change with updates and regional specifications, the exact number must be confirmed for your truck’s year and engine variant.
How to identify the exact part number for your Ram 2500 Cummins
To ensure you order the correct oil filter, follow these steps and verify against your vehicle’s details and current filter.
- Identify the engine size and model year from the VIN or owner’s manual.
- Inspect the currently installed filter for a stamped or printed part number.
- Check Ram/Mopar official documentation or service bulletins for the recommended oil filter PN for your year.
- Use reputable cross-reference resources or ask a dealer to map the OEM part to common aftermarket brands (Wix, Baldwin, Donaldson, etc.).
- Verify thread size, gasket type, and filtration capacity to ensure proper fit and sealing.
- If in doubt, contact a Ram dealer or Cummins specialist with your VIN to confirm the exact part number.
In practice, accuracy hinges on confirming the exact engine and year, since part numbers can shift with updates and regional variations.
Summary
The Ram 2500 Cummins does not have a single universal oil filter number. The correct part depends on whether you have the 5.9L (2003–2007) or the 6.7L (2007–present) engine, and on the specific production year. To obtain the exact part number, verify your engine and year, check the existing filter, consult official Mopar/Ram resources, and use trusted cross-reference tools or dealers. If you share your truck’s year and VIN, I can help pin down the precise filter PN and compatible cross-references.
