BEFORE YOU ORDER

Make the right match.

  1. Confirm whether your installed engine is a DD15 or DD13.
  2. Include the data plate, VIN and current installation photos.
  3. Check the supplied turbo, fuel-system equipment and electronics individually.
Are DD15 and DD13 engines interchangeable?
Do not assume interchange between engine families. A qualified installer must assess the complete truck application and proposed replacement.
Can I search specifically for a DD15 accessory?
Yes. Search by its OEM number or submit a request with the engine serial number and photos. State that you need a component rather than a complete engine.
What should I ask about an engine’s condition?
Ask what inspection or testing information exists for that stock item, what defects are known and which supporting photos or records are available.
