We've published a free heavy-duty truck encyclopedia at partsnow.ai/trucks: 24 makes, from Freightliner and Kenworth to Autocar and Western Star, with model pages, side-by-side comparisons and parts-fitment guides.
What's inside
Each make page covers the current and legacy model lineup; model pages include specs, common configurations and known maintenance patterns. Comparison pages put two models head-to-head (Cascadia vs T680, 579 vs VNL…), and fitment pages connect each model to the parts that actually fit it in our catalog.
Why we built it
Parts buying starts with the truck, not the part number. Making solid reference material free and public helps techs get to the right part faster — and keeps the answers next to live inventory instead of on a forum thread from 2014.
