We currently maintain build specs for Mack and Volvo Trucks. We also recommend using our All-Makes catalog to search for a variety of products that will fit your needs. We maintain a robust VIN database supporting vehicles dating back to 2007 for Volvo and 2010 for Mack. Older models may not be visible with this tool.

The Genuine Catalog is available to owners of Mack Trucks and Volvo Trucks. If you own Mack and/or Volvo and do not have visibility, please refer to previous FAQ, “how do I keep my VIN list current?” Owners of other truck brands are encouraged to order using our All-Makes Catalog.

Once the dealer has authorized your account set-up, simply login and begin shopping using the search functionalities or any of our integrated catalogs.
