About 4wd.ai
Build decisions before parts orders
4wd.ai is an independent fitment research product for owners planning tires, wheels and suspension changes.
The problem
Traditional year-make-model catalogs answer whether one part is listed for a stock vehicle. Modified trucks create a different problem: the outcome depends on several parts working together. Owners are left comparing forum posts that often omit wheel offset, trim, tire measurements or the conditions where rubbing occurs.
What we are building
Our first release organizes high-intent fitment questions into generation-specific guides and transparent calculators. The long-term product will evaluate complete configurations and improve through verified measurements and post-install outcomes.
Independent guidance
We are not a vehicle manufacturer, tire company or installation shop. Manufacturer names are used only to identify vehicles and supporting documentation. Editorial claims remain separate from any future commercial relationships.
