Any good parts person knows the value of a reliable parts interchange, especially in the trucking industry where unique specs, upfitting, modification and vehicle longevity can render VIN-based parts lookups inaccurate or outdated. A recent poll by Truck Parts & Service found that supplier websites and online search tools like Google and FleetCross are the preferred parts lookup methods for truck parts professionals, with Automann's website cited as the top choice.

Why it matters

Finding the right part interchange can sometimes be more challenging than actually sourcing the part itself. Truck parts experts rely on trusted lookup tools to quickly and accurately identify the right replacement parts, improving customer service, employee productivity, and sales. However, parts distributors say manufacturers often make cross-referencing overly opaque, creating frustration and slowing down the parts lookup process.

The details

According to the TPS poll, 40% of respondents use supplier websites as their preferred parts interchange lookup tool, with Google at 39% and FleetCross at 16%. Truck parts professionals say the best vendor sites provide robust product information to validate interchange data and confirm the right part match, eliminating the need for additional research. The Automann website was cited as the top choice, praised for its comprehensive cross-references and ease of use. Other popular options include Excelerator by Daimler Trucks North America and FleetCross. While online search can provide helpful starting points, distributors caution the information found online may not always be accurate and needs to be verified against vendor data.

  • The TPS poll was conducted in early 2026.
