To find the correct Fram filter:
1. Check your owner's manual: This is the best source. It will list the recommended oil filter part numbers from the manufacturer (Mopar). You can then use that information to find the equivalent Fram filter.
2. Look up your vehicle's information online: Use a reliable parts website (like AutoZone, Advance Auto Parts, or Napa Auto Parts) and enter your vehicle's year, make, model, and engine size. These sites will show you compatible filters, including Fram options.
3. Check the existing filter: If you can, look at the filter currently on your truck. The part number will be printed on it. You can then cross-reference this number with a Fram filter using an online parts catalog or by visiting an auto parts store.
Important Note: Don't solely rely on generic "fits 5.9L Dodge Ram" information. Slight variations between engine versions can affect filter compatibility. Using the wrong filter could lead to poor engine lubrication and potential damage. Always verify compatibility through one of the methods listed above.
