BEFORE YOU ORDER

Make the right match.

  1. Include the model, VIN and current component photos.
  2. Mention custom equipment or prior replacements that affect the repair.
  3. Check included brackets and trim on large exterior assemblies.
Are Peterbilt 389 and 579 body parts interchangeable?
Do not treat different model families as interchangeable. Confirm the part number, mounting arrangement and exact application.
Can a customized truck use the standard model filter?
The filter is a starting point. Describe modifications and send current photos so the specialist can check the installation actually on the truck.
How do I source a complete Peterbilt cab assembly?
Provide the VIN, cab type, required interior equipment and photos. Ask the team to identify all included and excluded components in the quote.
